Goertek SPA06-003

The SPA06-003 is a miniaturized Digital Barometric Air Pressure Sensor with a high accuracy and a low current consumption. The SPA06-003 is both a pressure and a temperature sensor. The pressure sensor element is based on a capacitive sensing principle which guarantees a high precision during temperature changes. The small package makes the SPA06-003 ideal for mobile applications and wearable devices. The SPA06-003‘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 in the application to convert the measurement results to true pressure and temperature values. The SPA06-003 has a FIFO that can store the latest 32 measurements. By using the FIFO, the host processor can remain in a sleep mode for a longer period of time between readouts. This can reduce the overall system power consumption. Sensor measurements and calibration coefficients are available through the serial I2C or SPI interface.
