Module Application
Tire Pressure Monitoring System (TPMS), bicycle lights , digital photo frame rotation, screen rotate, flip video camera , anti-theft system
Test Description
Our 51 development board using the tilt sensor module test
Wiring:
Module development board connected to VCC VCC
GND GND connection module development board
Connect the VCC and GND, module power indicator lights
The module level light up on the desktop , the module slowly rotating in one direction , the switch indicator lights , and then rotate in the opposite direction module back to the original state , the switch light off. This phenomenon is explained , changing the angle of the sensor can trigger module , so that the switch indicator lights.
Also inside information program with a 51 ,the tilt sensor module to detect high and low digital interface D0
Specifically as follows:
Wiring:
Module development board connected to VCC VCC
GND GND connection module development board
D0 module development board connected to P0.1
SCM : STC89C52
Serial Transmit Data Baud Rate: 9600
Phenomenon: the module to change the angle of the trigger , serial constantly sending 01 , while switch indicator light ;
No angle change does not trigger module , serial data is not sent , lights out
