ALLNET 4duino magnetický Reed senzor pre Smart Car (ALL_OY_3440)

The ALLNET 4duino Magnetic Reed Sensor is a reliable and easy-to-use digital sensor designed for smart car projects and automation. It detects the presence of a magnetic field and outputs a digital HIGH/LOW signal, making it ideal for position sensing, door/window alarms, and robotics. The sensor operates at 3.3V to 5V DC and is compatible with Arduino, Raspberry Pi, ESP32, and ESP8266 platforms. With a compact module size of 32 mm x 14 mm x 7 mm and mounting holes, it integrates seamlessly into your projects.

Advantages

This reed sensor offers a simple digital interface, fast response time (<1 ms), and a typical detection range of 5-15 mm. It includes three modules in the package, providing excellent value for prototyping and education. The on-board power LED indicates operation status, and the normally open (NO) contact configuration ensures straightforward integration.
