The acquisition of atmospheric pressure and temperature is also a necessary parameter in the accounting of atmospheric standards, we must know the pressure and temperature in order to calculate the parameters of the standard conditions, we need a can detect both the pressure and the temperature of the components.1 , hardware overviewMS5837 pressure sensor is a kind of sensor which can be used on the circuit board to detect 10-1200mbar pressure range,
Because the data acquisition station is basically installed in the field or the roof, the installation location and vibration have certain influence on the accuracy of the test data. So want to have a position state data, just found Kylin made on the ADXL345, such a digital output acceleration sensor. As shown in the red box:1 , ADXL345 OverviewADXL345 is a 3-axis, digital output accelerometer based on Imems technology from Adi. The characteristics of
