5V Laser Receiver Module – High Level Output Laser Light Detection Sensor for Arduino & Raspberry Pi

5V Laser Receiver Module — Laser Light Detection Sensor

This laser receiver module detects laser light and outputs a HIGH digital signal when the laser beam is detected. Designed for 5V systems, it is fully compatible with Arduino, Raspberry Pi, ESP32, and other microcontrollers. Pair it with a 650nm laser transmitter module to build beam-break sensors, security alarms, object counters, and more.

Key Features

• Outputs HIGH level when laser beam is detected
• Compatible with 5V microcontrollers: Arduino, Raspberry Pi, ESP32, STM32
• Works with standard 650nm red laser transmitter modules
• Digital output — easy to read with any digital GPIO pin
• Onboard LED indicator for visual detection feedback
• 3-pin interface: VCC, GND, OUT
• Compact PCB size for easy integration

Specifications
