Tilt Sensor with Digital Output for Arduino & Raspberry Pi

Warranty: None
Availability: In stock

This low cost tilt sensor can be used to detect orientation and motion of this board. It gives a digital output which changes when the board is tilted. This digital output can be connected to and Arduino/Raspbeery Pi or any other microcontroller to detect the tilt orientation of this board.

Tilt sensors allow you to detect orientation or inclination. They are small, inexpensive, low-power and easy-to-use. If used properly, they will not wear out. Their simplicitiy makes them popular for toys, gadgets and appliances. Sometimes they are referred to as "mercury switches", "tilt switches" or "rolling ball sensors" for obvious reasons.

They are usually made by a cavity of some sort (cylindrical is popular, although not always) and a conductive free mass inside, such as a blob of mercury or rolling ball. One end of the cavity has two conductive elements (poles). When the sensor is oriented so that that end is downwards, the mass rolls onto the poles and shorts them, acting as a switch throw.


  • This module uses the high-sensitivity switch SW 520D as the sensor
  • This module is equipped with mounting holes for easy mounting
  • Uses LM393 wide voltage comparator for clean output signal with good waveform and strong driving ability with output of more than 15 mA.
  • working voltage of 3.3V to 5V.
  • Small PCB size:3.2cm x 1.4cm.
  • Digital output form: digital switch output (0 and 1).
  • The output terminal can be directly connected to the micro controller to detect the angle change
  • The output terminal directly drive relay module to form a high-power tilt switch, protecting electrical equipment through automatic power off when the products tilt.
  • Adjustable sensitivity (shown in blue digital potentiometer adjustment)
