Introduction：

The SPL07-003 is a miniaturized Digital Barometric Air Pressure Sensor with a high accuracy and a lowcurrent consumption. The SPL07-003 is both a pressure and a temperature sensor. The pressure sensorelement is based on a capacitive sensing principle which guarantees a high precision during temperaturechanges. The small package makes the SPL07-003 ideal for mobile applications and wearable devices.The SPL07-003‘s internal signal processor converts the output from the pressure and temperature sensorelements to 24-bit results. Each pressure sensor has been calibrated individually and contains calibrationcoefficients. The coefficients are used in the application to convert the measurement results to truepressure and temperature values.The SPL07-003 has a FIFO that can store the latest 32 measurements. By using the FIFO, the hostprocessor can remain in a sleep mode for a longer period of time between readouts. This can reduce theoverall system power consumption. Sensor measurements and calibration coefficients are availablethrough the serial I2C or SPI interface.
