替代MS5540/MS5534绝压传感器0-200 KPA AS77

The AS77-02BA-00 employs a MEMS pressure sensor with an I²C interface to provide accurate temperature, pressure data. The sensor pressure and temperature outputs are digitized by a high resolution 24-bit ADC. Data compensation is integrated internally to save the effort of the external host MCU system. Easy command-based data acquisition interface and programmable interrupt control is available. Pressure output can be resolved with output in fractions of Pascal. Package is surface mount with a stainless steel cap and is RoHS compliant
