Icstation 5V laser sensor relay module outputs high level when it receives laser, otherwise it outputs low level.
The laser receiver is sensitive to ambient light, so please keep the sensor in dark environment. It is a non-modulated laser receiver. Light will interfere with the induction of the laser. We suggest shielding the sensor by a black tube if it must be in bright area.
This laser sensor switch has high sensitivity because it detects laser light from the front/back/side.
This is a pack of 5 pieces of laser receiver board. Laser transmitter is not included in the package. The sensor is bent for easier shipping. You can easily restore it
Too high input voltage, unstable power supply, reversed polarity will damage the sensor board. Please contact us immediately if you have any question or issue with your purchase.
