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 PIN2: VCC PIN3(IO1): Digital signal input PIN4(IO2): NC Microduino sensor can communicate with core module through the connection with Microduino-Module Sensor Hub.
