Page 5: Introduction
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. -

Page 9: Usage
Arduino Barometric condition is one of the criteria used to predict coming change in weather and deduce altitude above sea level. Here is a demo to show you how to read the barometric data from this Grove - Barometer Sensor. - Page 10 //pressure filter KalmanFilter a_filter; //altitude filter void setup() Serial.begin(9600); // start serial for output Serial.println("****HP20x_dev demo by seeed studio****\n"); Serial.println("Calculation formula: H = [8.5(101325-P)]/100 \n"); /* Power up,delay 150ms,until voltage is stable */ delay(150); /* Reset HP20x_dev */ HP20x.begin(); delay(100);...

Open the serial monitor to receive the sensor's data including temperature, barometric pressure value, relative atmosphere pressure and altitude.
