Reed Switch Sensor Module
Description:
Reed Switch Sensor Module is a simple yet highly effective magnetic sensor module designed for detecting the presence or absence of a magnetic field. It works based on a reed switch — a small electrical switch that operates when exposed to a magnetic field. When a magnet comes near the sensor, the reed switch closes (or opens, depending on configuration), changing the output signal of the module.
Features:
1. Detects the presence or absence of a magnetic field
2. Built-in high-quality reed switch for reliable operation
3. Digital output signal for easy interfacing
4. Power and output status indicator LEDs
5. Low power consumption
6. Compact and lightweight design
7. Long life with no physical contact operation
8. Easy to use with Arduino, Raspberry Pi, ESP8266, ESP32, STM32, and other microcontrollers
9. Suitable for magnetic proximity sensing and security systems
