Product Review
Icstation 5V laser recevier sensor module relay switch for Arduino, it is a non-modulated laser receiver module, has two layers circuit board, have given room for a mounting hole. It's sensitive to ambient light, please keep the sensor in the dark environment. Or it can be tripped by ambient light, suggest shielding the sensor by a black tube if it is necessary in bright areas.
Working voltage: 5V, module size: 1.52x2.22cm/0.6"x0.9". Output high electrical level when it with laser irradiation; output low electrical level when it without laser irradiation.
â¤Warm Tips:â¤
1. Users need to have relevant electronic knowledge to test this module, due to some improper use will damage the module, such as input voltage is too high, power supply is unstable, polarity reversed.
2. These sensor modules use non-modulated laser receivers, please keep them in a dark room when using. Natural light or other light sources will disturb them, suggest shielding the sensor by a black tube if it is necessary in bright areas.
3. The sensor is bent for easier shipping, user can adjust it easily.
4. The sensor module does not include a laser emitter, due to it has very few profits.
5. All of these sensor modules pass the quality inspection one by one before shipping.
Package included: 5pcs laser recevier sensor modules
Testing results:
When there is no laser irradiation, the relay module with high level action will not work.
When there is laser irradiation in front directly, the relay module with high level action will work.
When there is laser irradiation from the back, the relay module with high level action will work as well.
