Detailed Description：

WORKING PRINCIPLE：

DQJ series knocking sensing module is also called vibration sensing module, which is released on the sensing surface through the force of the knock action, and then converts the force into a piezoelectric signal. After the piezoelectric signal is converted by the circuit, combined with hardware and software filtering, the useful percussion signal is detected and output through the analog serial port.

Product	DQJ-1
Input Voltage	DC 5±0.3V
Operating Current	≤4mA
Induction Thickness	＜20mm
Response Time	＜1 sec.
Output Signal	Analog serial output
Operating Temperature	0~80℃
Storage Temperature	-40~85℃
