Reach-Sentinel-Lite-Software

Written for Bruin Spacecraft Group Reach Project 2017-2018. Contains the code for the on-board Arduino that will manage the data from the sensors.

Required Libraries:

• Adafruit_Sensor
• Adafruit_ADXL345_U (Accelerometer)
• Adafruit_HMC5883_U (Magnetometer)
• Adafruit_MPL3115A2 (Barometer)
• Adafruit_L3GD20_U (Gyroscope)
• Adafruit_MCP9808 (Temperature Sensor)
• RadioHead Packet Radio Library (Radio)

Libraries are included in the Required Libraries folder for convenience. All thanks to Adafruit.com and the RadioHead Packet Radio Library for providing open-source code.

Data Packet

This is the struct used to store each packet of data received from the sensors.

struct datapacket {
  unsigned long timestamp;
  float accel_x;
  float accel_y;
  float accel_z;
  float gyro_x;
  float gyro_y;
  float gyro_z;
  float mag_x;
  float mag_y;
  float mag_z;
  float mag_heading; 
  float temp_tempC;
  float baro_pressure; // in mmHg
  float baro_altitude; // in meters
  float baro_tempC;
};

Currently known bugs

• MAG_FLAG is set when magnetometer is disconnected
