description

bioVibez LX-AC-R2A-Wifi – Ambient light / LUX sensor automatic switch is a dual output / channel micro-controlled dusk to dawn sensor with user configurable relay output. The sensor come with a wide ambient light detection range up to 2000 lux. The sensor can be configured using a web browser on mobile or laptop by accessing the sensor as Wifi-access point.

Microcontroller based - A microcontroller-based design gives more precise timeouts and digital control.

Device configuration - The sensor acts as an access point for a mobile or laptop to connect by selecting the sensor from Wifi list. Once connected the sensor configuration can be accessed using a browser. (url - config.bv)

Note - No internet or apps download needed.

Independent LUX Set point (LIGHT) control - Both channel outputs can be separately enabled / disabled for ambient light sensing. Enabling LUX control will make sure lights connected to the output do not come on, if there is enough ambient room lighting (i.e. ambient room light is greater than the LUX set point (cut-off) value). De-activating LUX control allows the output to be used for non-lighting applications such as operating exhaust fans which need to be operated irrespective of the ambient light conditions.

Flash rejection filter - Flash rejection filter is useful for filtering unwanted light flashes like a passing vehicle with high beam or lightning flash. This filter slows down the response of the sensor output to switch from 'ON' to 'OFF'. This prevents and unwanted ambient light conditions to interfere with sensor output.

Start delay - Start delay timeout delays the output from switching 'ON' the output. This feature is useful reject temporary cloudy conditions or minor fluctuating ambient light conditions for eg. around sun set or special requirements.

Early shutdown - Early shutdown is useful when it is not required to wait till sunrise for the lights connected to sensor output to switch 'OFF'.

Factory reset - Channel parameters can be individually reset to factory default settings. Also, ‘Reset all’ setting will reset all parameters of both channels to factory default.

Factory reset - Channel parameters can be individually reset to factory default settings. Also, ‘Reset all’ setting will reset all parameters of both channels to factory default.

Backup & restore configuration - Sensor configuration can be backed up or can be recalled to or from mobile / laptop. This feature is useful as a back-up. Also, for mass installations where many sensors need to be installed with same or similar settings. One sensor can be configured and backed up to mobile and the same configuration can be downloaded to other sensors, without having to set all the parameters individually.

SMPS - for standby power savings. The module is powered by a built in universal SMPS (switched mode power supply).

Why dual outputs? - Practical application like a toilet/bathroom, where lights need to be controlled with both motion and ambient light. But, at the same time exhaust fan which should be controlled with motion only. Dual outputs make it an ideal choice for using in toilets / urinals / bathrooms where one channel (PIR + LUX control enabled) controls the light/lights and second channel (PIR) operates the exhaust fan. When there is proper ambient lighting, the lights will remain ‘OFF’ but the exhaust will switch ‘ON’. This cannot be accomplished using a single channel output. Also, something like a porch light needs to come ‘ON’ at sundown – one of the channels can be configured to with LUX only.

Dynamic set lux point - Dynamic set point is captured after a delay, once channel relay switches ‘ON’. The dynamic set point includes the new ambient lux value of the light attached to the outputs. This prevents hunting or race condition.

Ceiling or wall mounted - The sensor has a universal mounting design which allows for wall and ceiling mounted.

Polycarbonate enclosure - Fire retardant grade polycarbonate enclosure ensures safety and rigidity. Polycarbonate is more durable than ABS, as it does not degrade or change colour with exposure to sunlight.

PRECAUTION
Please note installing the bioVibez - dusk to dawn sensor requires electrical wiring. So, if you do not feel confident or safe performing these tasks, you should contact an electrician to install the sensor for you.
INSTALLATION LOCATION
Factors that help in fixing location
  • Choose a rigid mounting area on wall or pole.
  • The sensor should be properly as oriented as shown in figure 1.
  • The sensor should be affixed properly. If loosely mounted, any shaking due to wind or other vibrations can wrongly trigger it.
  • Make sure there no moving objects which can cause moving shadows in front of sensor.
  • The sensor should be mounted away from direct focus of lights.
  • Sensing window should be facing down. (See figure 1)

Frequently Asked Questions
General FAQ's
Motion sensors detect movement of objects and people. There are different types of motion sensors based on the detection object and detection methods. 2 types of motion sensors / detectors that are widely used to detect the presence/absence of people are PIR and microwave motion sensors.
Motion sensors/PIR sensors detect presence of a person by detecting the persons movement within the detection zone. With the help of control logic and relay mechanism lights and appliances can be switched "ON" or "OFF" when detection occurs. In other words, lights come on only when a person is present in the effective area – like a toilet / bathroom. This saves energy, as when the person leaves the lights are switched "OFF" automatically.
Motion sensors/PIR sensors get activated on sensing human presence based on motion or thermal radiation in case of PIR sensors. This when coupled with control circuitry and actuation mechanism like a relay – lights and appliances can be controlled and switched "ON" or "OFF" only when the person is in the area of detection. This give a dual benefit of (a) automation, (b) energy / power savings, (c) Ensure senior citizens safety by ensuring they do not have to reach out to a light switch.
Occupancy sensors detects the continuous presence of a person/persons within the detection zone. Occupancy sensors are based on thermal radiation or ultrasound or visual image processing or CO / CO2 monitoring, people counting (going in vs going out), etc. They may also employ a combination of two or more detection methods.
Occupancy sensors detects the continuous presence of a person/persons within the detection zone. If nobody is detected in the room (detection zone) control circuitry can will switch ‘OFF’ all lights, devices, air conditioner, fans, and other connected appliances. This saves a lot of energy and shaves down electricity bills.
Motion sensors as the name suggest detect motion within the field of view in case of PIR. If there is no motion, there is no detection. For example, it cannot detect a sleeping person as there will be not movement. Occupancy sensors on the other hand detects the continuous presence of a person/persons within the detection zone. As such motion detection sensors are useful for short duration application which involve intermittent (in seconds) motion detection, like in toilets or bathrooms, pathways, hotel or building corridors. Occupancy sensors are more suited for long duration (in hours) like bedrooms, living rooms, office cubicles, hotel rooms, etc.
No. Motion sensors as the name suggest detect motion within the field of view in case of PIR. If motion is not detected, the control circuitry will switch ‘OFF’ lights and appliances after the programmed timeout.
Some cheap occupancy sensors employ this method. But they are not true occupancy sensors. The higher timeout will keep lights and appliance ‘ON’ for the full timeout even if the room is empty wasting energy. Also, if there is no movement during the entire timeout as in case of a person sleeping, the control circuitry will switch of fans / air conditioner making the person get up in a sweat.
Passive Infra-Red (PIR) sensors use a pair of pyroelectric elements (or quad elements for higher sensitivity) to detect heat energy in the surrounding environment. These two sensors sit beside each other, and when the signal differential between the two sensors changes for example when a person enters the room, the sensor will trigger a detection signal.
Whenever the PIR motion sensor detects movement, it triggers the control circuitry which in turn actuates a relay or contactor switching on the connected light or appliance. Once the person leaves the detection area and no more motion is detected - a timeout is triggered. When timeout occurs, the control circuit disengages the relay and lights switch "OFF" (for example 10sec after last motion detection – lights will switch "OFF")
PIR motion sensor works on movement detection. It is not possible for a person to be moving continuously. The timeout works as a time buffer between movement detection. For example, if a timeout of 10 seconds is used, the person has the allowance of 10 seconds to be motion less. If motion is detected within the 10 seconds timeout is reset to 10 seconds and the cycle continues until no movement is detected within the timeout, in which case the control circuitry disengages the relay and switches ‘OFF’ the connected lights and appliances.
Timeouts are application specific and they depend on the estimation of how long a person in the detection zone will stay still or not move. It may need a little trial and error to get the optimum timeout. For example, if the PIR switch is used in an elevator. The timeout should be set considering the maximum time it takes for going from bottom to top. That is the maximum time the person can remain still.
In case a timeout occurs due to no movement and relays are disengaged, the person on realizing the lights or exhaust fan are "OFF" will most probably do some movement and the PIR sensor will detect the motion restarting the lights.
bioVibez motion sensor switch is just not only meant to control lights but also other appliances like exhaust fans in case of toilets. Lights need to be controlled with motion and also the ambient light. If there is enough daylight the LUX sensor on bioVibez will disengage the channel relay on which LUX sensing is enabled and keep lights "OFF" even when there is motion. But in case of exhaust fan its use not dependent on the amount of ambient light and needs to be on a separate channel with LUX sensing disabled.
Refer the model specific setup manual to set the ‘DIP switches’ for the timeout delay required. For WiFi config models timeouts can be set using a phone or PC. Refer to device specific manual for more details.
Refer the model specific setup manual to set the ‘DIP switches’ for enabling/disabling LUX sensing for a channel. For WiFi config models LUX sensing can be enabled/disabled using a phone or PC. Refer to device specific manual for more details.
2nd Gen - bioVibez PIR/LUX sensor onwards and WiFi config have this feature. Refer the model specific setup manual to set the ‘DIP switches’ for enabling/disabling PIR motion sensing on a channel. For WiFi config models PIR motion sensing can be enabled/disabled using a phone or PC. Refer to device specific manual for more details.
Refer the model specific setup manual to set the ‘DIP switches’ for setting LUX levels. Note this setting applies for both channels.
For WiFi config models LUX level can be set for both channels independently using a phone or PC. Refer to device specific manual for more details.
Yes, outputs of more than one bioVibez PIR/LUX sensor can be connected in parallel. Care has to be taken to make sure the phase and neutral wires match. For example for a multi entry/exit point corridor or lobby where it is not possible to cover all entry points with a single sensor, bioVibez PIR/LUX sensors can be installed at each entry/exit and outputs drawn parallel to a common light.
Yes, one of the channel outputs can be connected to a standalone alarm/hooter. LUX sensing should be disabled. The setup will need to be armed and disarmed manually.
There is delay of ~2 seconds from first detection to channel output activation.
PIR sensors detect movement on basis infra-red radiation difference between its pyroelectric elements. A false detection can happen if the sensor is placed directly in front of an air conditioner or too close to a fan. The flowing air can register different temperatures on the pyroelectric elements causing false detection. The sensor should be placed away from any possible strong draft of air.
The channel-2/relay-2 modes set the operation behaviour for channel-2. If parallel mode (default) is selected both channel-1 and channel-2 outputs are triggered together on PIR detection. For sequential mode – channel-2 output is triggered after channel-1 timeout. Sequential mode is useful where channel-2 should not be triggered during the time the person is in detection zone, but after channel-1 times out. Refer to device manual for more details.
The motion detection angle is around 120 degrees. The range is ~4m (~13ft)
