ALLNET 4duino Tilt Sensor Module (SW-520D) for Arduino, Raspberry Pi, ESP32

The ALLNET 4duino Tilt Sensor (4duino_B15) is a compact and reliable tilt detection module designed for microcontroller projects. Based on the SW-520D mechanical rolling ball switch, it provides a digital HIGH/LOW output when the module is tilted beyond a certain angle. Ideal for level detection, anti-theft alarms, motion sensing, and interactive projects.

Advantages

Easy to integrate with 3-pin header (VCC, GND, Digital Output). On-board power and status LEDs for immediate visual feedback. Low power consumption (<10mA) suitable for battery-powered applications. Compatible with 3.3V and 5V logic levels.

Suitable for

• Level detection and orientation sensing
• Anti-theft alarms and tamper detection
• Motion-activated projects
• Educational robotics and Arduino experiments
