• The company produced normally closed type vibration sensor SW-420
• The comparator output, signal clean, good waveform, driving ability is strong, for more than 15 mA
• The working voltage of 3.3V to 5V
• Output form : digital switch output (0 and 1)
• Has a fixed bolt hole, convenient installation
• Small board PCB size : 3.2cm x 1.4cm
• Use the LM393 wide voltage comparator

Module directions for use:

• Product no vibration, vibration switch is closed on state, the output terminal output low level, the green light is lit
• Product vibration, the vibration switch instantaneous disconnection, output the 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, call the police
• Color and more details are shown as pictures
• PLEASE NOTE that due to lighting effects, monitor's brightness/ contrass settings ect, there could be some slight differences in the color tone of the pictures and the actual item!
