The Sense HAT module
Sense HAT is an add-on board for Raspberry Pi 2 and 3, but it works with Raspberry Pi Zero as well. It was made especially for the Astro Pi mission.
The Sense HAT module looks as follows:

You can buy this from the official website, https://www.raspberrypi.org/products/sense-hat/. Sense HAT allows Pi to sense the world around it. With Sense HAT, we can display messages and images, control the orientation, gather sensor data, and respond to movement. As a result, Sense HAT is the easiest way of adding a ton of sensors to your Raspberry Pi Zero W board without buying and connecting jumpers to the breadboard. Sense HAT has the following functionalities:
- Orientation (yaw, pitch, and roll) via an accelerometer, 3D gyroscope, and magnetometer
- Temperature
- Humidity
- Pressure
It is also equipped with an 8x8 LED matrix that allows you to display data via various sensors. Through the LED matrix, you can also find which way geomagnetic North is by programming a compass using the magnetometer...
