Description HP209 Pressure Sensor employs a MEMS pressure sensor with an I²C interface to provide accurate temperature, pressure or altitude data. The sensor pressure and temperature outputs are digitized by a high resolution 24-bit ADC. The altitude value is calculated by a specific patented algorithm according to the pressure and temperature data. 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. Typical active supply current is 5.3μA per measurement-second while the ADC output is filtered and decimated by 256. Pressure output can be resolved with output in fractions of 0.1 Pascal. Features: Supply voltage: 1.8V to 3.6V Pressure Ranges from 0 to 2…..200Kpa Fully data compensated Direct Reading, compensated： – Pressure: 20-bit measurement – Temperature: 20-bit measurement Standby current<0.1μA Operation temperature: -40 to 85℃ High-speed I²C digital output interface Size: 9.0 x 9.0 mm Applications: Panel Meter Industrial Pressure and Temperature Sensor System Automotive Systems Medical Gas Control System Fire Suppression System Blocked Filter Detection Heating, Ventilation, Air Conditioning White Goods Tank Level Measurement
