Arduino Tilt Sensor Module-SW420

The tilt sensor module detects inclination using two balls inside the sensor. When the inclination reaches a certain angle, the two small balls inside separate from the connectors under the sensor and function as open switches. In an upright position, the balls touch the connectors on the leg of the sensor and close the switch. Sensitivity adjustment can be made with the potentiometer on the module. Thanks to the LM393, information from the sensor passes through the comparator, and the status of the sensor can be observed via the LEDs on the module.
