This Grove - Barometer (High-Accuracy) Sensor features a HP206C high-accuracy chip to detect barometric pressure, altitude and temperature. It can measure pressure ranging from 300mbar~1200mbar with a super high accuracy of 0.01mbar (0.1m) in ultra-high resolution mode. The chip usuallu only accepts 1.8V to 3.6V input voltage but with an outer circuit added, this module becomes compatible with 3.3V and 5V. It can therefore be used on Arduino/Seeeduino or Seeeduino Stalker without modification. It is designed to be connected directly to a micro-controller via the I2C bus. Features Digital two wire (I2C) interface Command-based Reading, Compensated (Optional) Programmable Events and Interrupt Controls Full Data Compensation Wide barometric pressure range Flexible supply voltage range Ultra-low power consumption Altitude Resolution down to 0.01 meter Temperature measurement included Application Ideas Enhancement of GPS navigation Indoor and outdoor navigation Leisure and sports Weather forecast Vertical velocity indication(rise/sink speed) Documents Please visit the wiki page for more info about this product.
