Mini digital barometric sensor Goertek SPL07-003 with low current consumption and 32 measurement FIFO buffer
Product Overview
The SPL07-003 is a miniaturized Digital Barometric Air Pressure Sensor offering high accuracy and low current consumption. It functions as both a pressure and temperature sensor, utilizing a capacitive sensing principle for precise measurements even with temperature fluctuations. Its compact size makes it ideal for mobile and wearable applications. The internal signal processor converts sensor outputs to 24-bit results, with individual calibration and coefficients provided for accurate pressure and temperature conversion. The integrated FIFO buffer stores the latest 32 measurements, allowing the host processor to remain in a low-power sleep mode between readouts, thus reducing overall system power consumption. Sensor data and calibration coefficients are accessible via I2C or SPI interfaces.
