100. Light Sensor Calibration.
This configuration defines the calibrated scale for ambient light intensity. Due to the method and position that the
sensor mounted and the cover of sensor will bring measurement error, you can get more real light intensity by this
parameter setting. You should run the steps for lux sensor calibration
To use this calibration accurately, you must use a accurate lux meter such as this:
https://www.amazon.com/HDE-
LX-1010B-Digital-Luxmeter-Display/dp/B00992B29I
(https://www.amazon.com/HDE-LX-1010B-Digital-Luxmeter-
Display/dp/B00992B29I)
(This is purely an example, the more accurate lux meter you have, the better calibration
setting you will be able to use).
1) Set this parameter value to default (Assumes the sensor has been added in a Z-Wave Network).
2) Place a digital luxmeter close to sensor and keep the same direction, monitor the light intensity value
(Vm)
and
record it. At the same time you should record the value
(Vs)
of your digital luxmeter.
3) Calculate k = Vm / Vs. to get k coefficient.
4) The value of k is then multiplied by 1024 and rounded to the nearest whole number.
5) Set the value you got in 4 to this parameter and push the setting to your TriSensor.
For example, Vm = 300, Vs = 2600, then
k = (2600 / 300) * 1024
k = 8.6667 * 1024 = 8874.7 ≈ 8875 (Round up)
The parameter should be set to 8875.
