DPS310XTSA1 编带
The DPS310 is a miniaturized Digital Barometric Air Pressure Sensor with a high accuracy and a low current consumption, capable of measuring both pressure and temperature. The pressure sensor element is based on a capacitive sensing principle which guarantees high precision during temperature changes. The small package makes the DPS310 ideal for mobile applications and wearable devices. The internal signal processor converts the output from the pressure and temperature sensor elements to 24 bit results. Each unit is individually calibrated, the calibration coeȄicients calculated during this process are stored in the calibration registers. The coeȄicients are used in the application to convert the measurement results to high accuracy pressure and temperature values.
