Barometric Pressure Sensor/Altimeter/Temperature Sensor I2C - BMP180

Barometric Pressure Sensor/Altimeter/Temperature Sensor I2C - BMP180

Product information:

The BMP180 is a very energy efficient and very small barometric pressure sensor with high sensitivity.

Because the pressure is related to the height at which you are located, you can also calculate the height at which your circuit is located.

The sensor has a measuring range of 300-1100hPa (9000 meters above sea level to 500m below sea level).
The BMP180 has an I2C bus and can therefore communicate directly with many microprocessors (including of course the Arduino).
With the temperature sensor that is also built in, you almost have a complete weather station!
Simply connect the power supply, SDA and SCL to your Arduino, run the code and you can start measuring!

If you want to know exactly how to connect it, send me an email and I will send you a link to a tutorial and the Arduino program.
You can also find a good explanation of I2C on YouTube, just search for 'Jeremy Blum I2C tutorial'.

Supply voltage VCC: 1.8 - 3.6V (NOTE! Do not apply 5V, use the 3.3V connection of your Arduino!)
Precision in low-power mode: 0.06hPa (0.5m)
Precision in high linear mode: 0.03hPa (0.25m)
Working temperature: -40 to +85C, +/- 2C accuracy.
