Watch the video below to learn more about this awesome DIY Arduino watch that uses a GY-87 sensor board, that offers three sensors in the form of HMC5883L for the compass, BMP085 for the pressure ...

T. K. Hareendran shows us a simple setup to explore the capabilities of the Bosch BMP280 pressure sensor with your Arduino.

The sensor shown here is essentially two plates mounted side-by-side, attached to an Arduino Nano using the Capacitor library which uses just two pins, one digital and one analog.
