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.
Features:
Normally closed type vibration sensor SW-420. The comparator output, signal clean, good waveform, driving ability is strong, for more than 15 mA. Has a fixed bolt hole, convenient installation. Use the LM393 wide voltage comparator. Model: SW-420 Type: Normally closed Working voltage: 3.3V to 5V Output form: Digital switch output (0 and 1) Size: 32 x 14mm / 1.26" x 0.55"
Module directions for use:
When the vibration switch is closed, the output terminal output low level, the green light is lit; When the product vibration, the vibration switch instantaneous disconnection, the output terminal output high level, the green light is not bright; 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, alarm alert.
