SW-420 Motion Sensor<\/li>\n
Condition: New<\/li>\n
Purpose:<\/li>\n
Used to trigger the effect of various vibration, theft alarm, intelligent car, earthquake alarm, motorcycle alarm, etc.<\/li>\n
This module is compared with the normally open type vibration sensor module, vibration trigger for longer periods of time, can drive the relay module<\/li>\n
Module features:<\/li>\n
2. The comparator output, signal clean, good waveform, driving ability is strong, for more than 15 ma<\/li>\n
3. The working voltage of 3.3V to 5V<\/li>\n
4. Output form: digital switch output (0 and 1)<\/li>\n
5. Has a fixed bolt hole, convenient installation<\/li>\n
6. Small board PCB size: 3.2cm x 1.4cm<\/li>\n
7. Use the LM393 wide voltage comparator<\/li>\n
Module directions for use:<\/li>\n
1. Product no vibration, vibration switch is closed on state, the output terminal output low level, the green light is lit<\/li>\n
2. Product vibration, the vibration switch instantaneous disconnection, output the output high level, the green light is not bright<\/li>\n
3. Output can be directly connected to microcontroller, through single chip microcomputer to detect the high and low level, thus to detect whether there is a vibration environment, call the police<\/li>\n<\/ul>\n<\/div>\n<\/body>","protected":false},"excerpt":{"rendered":"
