Introduction
The KY-008 Laser Transmitter Module emits a red laser beam with a wavelength of 650 nm and an output power of 5 mW. It operates at a voltage of 5V and consumes less than 40 mA of current. The module features a 650 nm red laser diode, a resistor, and three male header pins. It is commonly used in laser pointer applications and is compatible with microcontrollers like Arduino, Raspberry Pi, and ESP32.
How to Use the KY-008 Laser Module?
This is one of the simpler modules and needs very little interaction. Unless you need to check the laser’s power state, you can put the sensor in a separate circuit. To get the ‘tripwire’ function working, you just need to connect the photo sensing module to your device.
The KY-008 laser module only needs to be connected to the power pins, unless you need to turn the laser on and off when it’s not in use. The VCC (+) pin connects to the 5V pin on the Raspberry Pi (the red one), and (-) GND connects to the ground pin (the black one). Alternatively, you can connect the laser module to any 5V power source and use the photosensor module to turn sensing on and off.
