This is a easy to use tilt sensor with a digital output. The sensor contains a potentiometer to set the tilt angle threshold. When the sensor is turned beyond the threshold point, the digital output goes high.
 
The comparator output signal is clean, good waveform, driving ability, more than 15mA. Switch module output depends on the angle of the switch is turned on and off, when the angle switches off, DO output high angle switch is turned on, DO output low. The output can be directly connected to the microcontroller through the microcontroller to detect high and low, thereby detecting the angle change. The output of the module can directly drive relays, which can be composed of a high-power switching angles to protect electrical equipment and other products when dumped automatic power-off function.
