Sensor Board
Generic Info
Board is connected using I2C to the Cubieboard
Sensors on Sensorboard
2x MS5611
Absolute pressure sensor
Range 10 .. 1200 mbar
Resolution up to 0.012 mbar
Adr 0x77 and 0x76 (7Bit)
Datasheet
MPU9150
Gyro, accelerometer, magnetometer and digital motion processor.
Adr 0x68 (pin AD0 low) or 0x69 (AD0 high) (7bit)
AMS5915
Differential pressure sensor Range 50mbar (max. 300 km/h IAS) Resolution <0,004 mbar (50 mbar, FSO 13107 counts) Adr 0x28 (7bit) Datasheet
(MS4525HRD - Not installed on sensorboard, would be an alternative to AMS5915, not yet available)
Differential pressure sensor, possible alternative to AMS5915?
24bit resolution (overkill?) and nice form factor (barbed connectors sideways)
Pinout similar to AMS5915, maybe PCB layout could accomodate both sensors?
Adr 0x77 and 0x76 (7Bit) - same as MS5611 and MS5803
Datasheet
Temperature Sensor DS1820
Temperature sensor shall be mounted in free airstream → not mounted on PCB
Connector 3.5mm stereo plug
LX8000/9000 uses the same sensor
Datasheet
good accuracy, good form factor, not I2C but single wire interface
Other stuff
I2C to single wire bridge
I2C EEPROM for calibration data storage
