Use:
For a variety of seismic triggering effect, reported the alarm, intelligent vehicle, electronic blocks.
Please note that this module to small vibration in the induction trigger time will be very short, not enough to drive the relay, some data can be directly and the relay module, the practical application effect, this shop does not want to mislead consumers, if you need to shake and trigger relay, please buy with the time delay function module
The module features:
1, the sensitivity of vibration switch is produced by our company, the default SW-18010P vibration sensor,.
2, the comparator output signal waveform, clean, good, strong drive ability, more than 15mA
3, working voltage 3.3V-5V
4, the output: digital switch output (0 and 1)
5, a fixed bolt holes, easy to install
6, small PCB size: 3.2cm x 1.4cm
7, the use of wide voltage comparator LM393
Module wiring instructions:
1.VCC: the positive pole of a power supply
2.GND: with the negative electrode of the power
3.DO: digital signal output
4.AO: with this vibration sensor which is invalid
Module for use:
1, the product is not vibration, vibration switch is disconnected, the output end outputs high level, the green indicator light is not bright;
2, product vibration, vibration switch transient conduction, the output low, the green indicator light;
3, the output can be directly connected with the MCU, the MCU to detect high level, thereby detecting the environment if there is shock, play the function of alarming
