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. 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. Crash Sensor General Pin Out Sensor / Trinket's Pin Out PIN1 (GND) GND PIN2 (VCC) VCC PIN3 (GPIO-A) Digital Input PIN4 (GPIO-B) Not Connected General Pin Out is the standard pin out of a Sensor / Trinket connector. Sensor / Trinket's Pin Out is this specific Sensor / Trinket's wiring in relation to the General Pin Out. GPIO-A / GPIO-B are signals that could be digital input, digital output, analog input or analog output. Or special signals such are serial communication or other special signals. Not Connected refers to the Pin is not used for this particular Sensor / Trinket. Features With small size, which is easy to install; It can be used as key switch and limit switch; It feels gentle. Specification Sensor voltage 3.3V~5V working voltage Size of the sensor Size of the board: 23.5mm*13mm 1.27mm-spacing 4Pin interface connected with sensorhub. CAD drawing of the sensor: File:Sensor CAD.zip Function description The static signal of the sensor is HIGH. After being pressed, the signal changes into LOW. Connection This sensor can be connected to the following interfaces of the core: D2~D13,A0~A7 Document Schematic diagram: File:Sensor-Crash.Zip.pdf Main sensors: File:Sensor-Crash-datasheet.pdf Development Program Download Download and unzip the program File:Sensor Crash Test.zip Programming Follow the Software Getting Started Guide.
