Product Overview
The SPL16-005 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, and each sensor is individually calibrated with coefficients for converting measurements to true pressure and temperature values. The integrated FIFO buffer can store up to 32 measurements, allowing the host processor to conserve power by remaining in sleep mode for extended periods. Key advantages include a wide absolute pressure range, low average current consumption, and an embedded 24-bit ADC with I2C interface.
