DPS368 TM Digital XENSIV barometric pressure sensor Product Description The DPS368 is a miniaturized Digital Barometric Air Pressure Sensor robust against water, dust and humidity. It offers 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 DPS368 ideal for mobile applications and wearable devices. Due to its robustness it can be used in harsh environment. 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 coefficients calculated during this process are stored in the calibration registers. The coefficients are used in the application to convert the measurement results to high accuracy pressure and temperature values. The result FIFO can store up to 32 measurement results, allowing for a reduced host processor polling rate. Sensor measurements and calibration coefficients are available through the serial IC or SPI interface. The measurement status is indicated by status bits or interrupts on the SDO pin.
