The comparator output signals clean, good waveform, driving ability, than 15mA
Working voltage of 3.3V-5V
The output form: digital switching output (0 and 1)
A fixed bolt hole for easy installation
Small PCB board size: 3.2cm x 1.4cm
Using a wide voltage comparator LM393
Module wiring instructions
VCC: positive power supply
GND: negative one
DO: digital signal output
AO: With this shock sensor this function is invalid
Description
When the product does not shock, vibration switch OFF state, the output of high output, the green light does not shine
When the product is shock, vibration switch is turned on instantly, output of low output, the green indicator light
The output can be directly connected to the microcontroller through the microcontroller to detect high and low, after detecting whether the environment there is is, play a role in the police
