The WF285A is a low-power, high-accuracy barometric pressure and temperature sensor. It comes in the LGA package with digital I2C interfaces. The pressure sensor element is based on a capacitive sensing principle which guarantees high precision during temperature changes. Its small dimensions make the pressure sensor for UAV (unmanned aerial vehicle) cruises, mobile applications, GPS modules and wearable devices.
The sensor’s internal signal processor converts the output from the pressure and temperature sensor elements to 24-bit results. Each pressure sensor has been calibrated individually and contains calibration coefficients. The coefficients are used to convert the measurement results to true pressure and temperature values.
The integrated FIFO of the sensor can store the latest 32 output results.
