Microduino-Crash Sensor is a sensor which can perceive collision.
+
The product number of Sensor-Crash is : '''MSDS11'''
  
−
It is used to detect if there is collision or crash. Therefore, it can also be called crash signal sensor. Due to different collision position, it can classified as left-crash sensor or right-crash sensor. Crash switch can turn mechanical quantity to electricity. When this sensor collided with an object, it'll cause circuit switch close. So, the circuit loop will be opened, the LED will be lighten and the voltage between the two sides of the sensor will turn high level to low. Microduino-Crash judges collision by detecting the electrical level between its two side. It can used in limit and anti-collision such as 3D print motor limit switch and robot anti collision.

Microduino-Crash Sensor

The product number of Sensor-Crash is : MSDS11

Sensor-Crash is a crash sensor, which is used to detect whether a crash has happened, and it can be also named crash signal sensor.

Because of the different position of crash, it can be divided into left crash and right crash sensor.


Introduction of Sensor Pin

  • Pins of the sensor:
    • PIN1: GND
    • PIN2: VCC
    • General signal pins:
      • PIN3(IO1): digital/analog signal
      • PIN4(IO2): NC(null)
    • Special signal pins:
      • If it is IIC: IO1/IO2 are respectively SDA/SCL.
      • If it is soft serial port: IO1/IO2 are respectively tx/rx.
  • Special to Sensor-Crash sensor pins
    • PIN1: GND
