1. Introduction
This Grove - Barometer (High-Accuracy) Sensor features a HP206C high-accuracy chip to detect
barometric pressure, Altimeter and temperature. It can widely measure pressure ranging from
300mbar~1200mbar, with a super high accuracy of 0.01mbar (0.1m) in ultra-high resolution mode. The
chip only accepts 1.8V to 3.6V input voltage. However, with outer circuit added, this module becomes
compatible with 3.3V and 5V. Therefore, it can 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.
