PRODUCT DETAILS

Description

LIGHT Unit is a light intensity detection sensor that integrates a photoresistor and a 10K adjustable resistor. It is capable of detecting light intensity and setting a threshold value for light intensity. The resistance of the photoresistor decreases as the incident light intensity increases. By detecting the voltage change, the sensor obtains light intensity data through analog-to-digital conversion.

To achieve more accurate light intensity detection, this unit also incorporates an LM393 dual differential comparator. It is used to compare the differential voltage between the photoresistor and the pressure-sensitive resistor.

    Works great.

    Currently using it with an atom lite to control outside lighting. Works great as expected.

    Good units, could be better

    I expected the trimmer pots to enable me to balance multiple light sensors so they would return the same analog value from the same light. I was going to use them as part of a solar tracker. Instead, I modified my project to use the DLIGHT module.

    What the trimmer does is set the point at which the digital signal switches between 0 and 1.
