HP206C 24bit Precision Barometer/Altimeter
add to cart
The HP206C 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 5.3 μA per measurement‐second while the ADC output is filtered and decimated by 256. Pressure output can be resolved with output in fractions of a Pascal, and Altitude can be resolved in 0.1 meter. The HP206C is offered in a 6.3 mm x 6.8 mm x 3.0 mm package and specified for operation from -40°C to 85°C.
