Digital Pressure Sensor
Digital Barometric Pressure Sensor for Portable Devices
Product Description
The WF282 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 WF282 ideal for mobile applications and wearable
.devices
The WF282‘s 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 WF282 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 I2C or SPI interface. The measurement status is indicated by status bits or
interrupts on the SDO pin.
