Description
- SW-420 Motion Sensor
- Condition: New
- Purpose:
- Used to trigger the effect of various vibration, theft alarm, intelligent car, earthquake alarm, motorcycle alarm, etc.
- This module is compared with the normally open type vibration sensor module, vibration trigger for longer periods of time, can drive the relay module
- Module features:
- 2. The comparator output, signal clean, good waveform, driving ability is strong, for more than 15 ma
- 3. The working voltage of 3.3V to 5V
- 4. Output form: digital switch output (0 and 1)
- 5. Has a fixed bolt hole, convenient installation
- 6. Small board PCB size: 3.2cm x 1.4cm
- 7. Use the LM393 wide voltage comparator
- Module directions for use:
- 1. Product no vibration, vibration switch is closed on state, the output terminal output low level, the green light is lit
- 2. Product vibration, the vibration switch instantaneous disconnection, output the output high level, the green light is not bright
- 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
