Grove - Barometer (High-Accuracy)

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.

A barometer is a widely used weather instrument that measures atmospheric pressure (also known as air pressure or barometric pressure) -- the weight of the air in the atmosphere. It is one of the basic sensors included in weather stations. Barometers have evolved through the centuries and come in all shapes and sizes. It is also used in more industries than just the weather and climate sectors.

Features

• Three-in-one measurement: Barometric pressure, Altimeter, and temperature measurement included that measures the pressure and the temperature by an internal 24‐bit ADC and compensates them by a patented algorithm
• Wide barometric pressure range: Pressure measurements range from 300mbar~1200mbar
• High-accuracy: Altitude resolution down to 0.01 meter
• Digital two-wire (I2C) interface: High-speed I2C Digital Output Interface (Up to 10 MHz)
