Descriptions
AS23F is a digital barometric pressure sensor especially designed for applications requiring highly-precision pressure measurement like quad copter altitude control and portable navigation device. It is both a pressure and temperature sensor housed in a compact 2.5×2.0×1 mm package. The pressure sensor is based on the industry-recognized piezo resistive technology featuring long-term stability and EMC robustness. Ahigh-performance 24-bit ADC provides pressure resolution up to 0.06Pa, and temperature resolution up to 0.1℃. The pressure sensor has a wide operating range from 300 to 1200hPa that covers all surface elevations on earth. AS23F can detect absolute barometric pressure with highly accuracy for applications like quad copter altitude control. The maximum altitude resolution can be up to less than 5cm. Several operation options further offer large window for user optimization on the power consumption, resolution and filter performance.
