niversal Motorcycle Car Vibration Induction Adjustable Sensor Anti-Theft Alarm High Sensitivity Device with XH2.54-3P Plug
Features:
brand new and high quality
Uses a vibration detection system that consists of a bell and a contact spring.
Characterized by high sensitivity, speed and high performance.
It is widely used in car anti-theft and other security products.
The internal piezoelectric ceramic sheet and the spring weight structure are used to detect the vibration signal.
The amplifier signal is amplified by the lm358 and output control signals.
Low cost, high sensitivity, stable and reliable operation, large adjustable range of vibration detection.
In the anti-theft system for steam cars and motorcycles, 80% of vehicle alarms use these sensors.
The sensor uses smt chip technology inside, and the imported components are assembled.
Can also be combined with a single chip microcomputer, wireless transmitter module, wired alarm, etc.
It is used in combination and has a wide range of uses.
Leading wire description:
1. the blue line is the signal output by the 358 op amplifier. If the
signal is not vibrated, it is high (the io port must be pulled up), and
if the signal is vibrated, it is low (signal to earth) .
2. red line power: + 12 v
3. the black line is the earth line
Notice:
If the output is connected at the high level, it needs to add a
resistor of 100 ohms or less. If you want to drive the wireless
transmitter module, you cannot replace the resistor. The red and black
wires are connected to the positive and negative power input of the
module. The number (alarm horn dc) is preferably an external relay
control to avoid major current damage to the internal components of the
sensor (for reference).
