--through the LM358 and other operational amplifiers to amplify and output control signals, with low cost, high sensitivity, stable and reliable operation, vibration
--The advantages of a large adjustable range of detection are widely used in automobile and motorcycle anti-theft systems. At present, 90% Most car alarms use this type of sensor.
--The inside of the sensor adopts SMT patch technology and is assembled with imported components. The sensor can also be connected with single-chip microcomputer, wireless
--The transmitter module, wired siren, etc. are used together, and are widely used.
--The sensitivity is adjustable. It is suitable for all kinds of security products, testing products, etc., and can be directly connected to the IO port of the microcontroller docking. The output of this vibrator is isolated by a diode, which can be used in parallel with the original car vibrator or multiple vibrators
Pin Definition:
1.Blue line: signal output, a periodic pull-down signal is output when a vibration is detected, which can be combined with the microcontroller interface. When connecting to the microcontroller, please pull a resistor on the IO port, so that it usually maintains a high potential and vibrates.
When inducting, pull it to a low level, and when the output is pulled up 5V, it usually outputs 5V, and when it is pulled up to 12V, it outputs 12V, when there is vibration, output low level (theoretically 0) to ground.
2. Black line: ground
3. Red line: positive power supply 5-15V DC
Description:
Name: car vibrator sensor
technical parameter:
1. Output current: ≤100mA (maximum load current)
2. Quiescent current: ≤6mA
3. Rated working voltage: 12V
4. Working voltage: 5-15V
Lead Description:
1. The blue line is the signal output through the 358 op amp output, and it is high level when there is no vibration (note that the output pin must be
Pull up a resistor), low level when there is vibration.
2. Red line power supply: +12V
3. The black wire is the ground wire
Packing list:
1 x car vibrator sensor
