RASPBERRY PI AND SENSE HAT (I): MEASURING TEMPERATURE, HUMIDITY AND PRESSURE
- Layout for this exercise:
1 - Introduction
- The Sense HAT is an add-on board for Raspberry Pi made especially for the Astro Pi mission (it launched to the International Space Station in December 2015) and is now available to buy.

- The Sense HAT has an 8×8 RGB LED matrix, a five-button joystick and includes the following sensors:
- Accelerometer
- Magnetometer
- Temperature
- Barometric pressure
- Humidity
- Gyroscope
- Also, there is a Python library providing easy access to everything on the board:

- To install Sense Hat on Raspberry Pi:
2 - Displaying text
- A basic exercise to check whether Sense Hat is working correctly:
3 - Measuring temperature, humidity and pressure
- Sense HAT has got built-in sensors for temperature, humidity and pressure:
- Giving execution permissions:
- Running the Python script:
- About the temperature readings it is important to notice that the Sense HAT sensor gets a little extra warm because of the heat generated by the Raspberry Pi module.
