HOPERF HIGH-PRECISION BAROMETER AND ALTIMETER SENSOR 6862I

Descriptions

 The 6862I is a digital absolute barometric 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 principle which guarantees high precision during temperature changes. The waterproof design makes the 6862I ideal for mobile applications and outdoor devices. The 6862I’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 6862I’s internal FIFO can store up to 32 measurement results, allowing for a reduced host processor polling rate.
