Product description
Use:For a variety of vibration trigger function, reported theft alarm, intelligent car, electronic building blocks, etc..Please note that this module in the induction of small vibration when the trigger time is very short, not enough to drive the relay, some of the information can be directly connected with the relay module, the actual use of poor results.Module features:1, the use of the company's production of high sensitivity vibration switch, the default SW-18010P vibration sensor,.2, the comparator output, the signal is clean, good waveform, strong driving ability, more than 15mA3, working voltage 3.3V-5V4, output form: digital switch output (0 and 1)5, with fixed bolt hole, easy installation6, small size: 3.2cm x 1.4cm PCB7, the use of wide voltage LM393 comparator
Module wiring instructions:
1.VCC: connected to the positive electrode
2.GND: power supply negative
3.DO: digital signal output
4.AO: this function is not valid with this vibration sensor
Module description:
1, the product does not vibrate, the vibration switch is off state, the output of the output level, the green indicator light is not bright;
2, the product vibration, vibration switch instant conduction, the output terminal low level, green indicator light;
3, the output can be directly connected with the microcontroller, through the microcontroller to detect high and low levels, which is to detect whether there is a vibration environment, play a warning role
