The Sense HAT is an official add-on board that adds a range of motion sensors to Raspberry Pi, including a gyroscope, accelerometer, and magnetometer, along with temperature, pressure, and humidity sensors. It also features an 8×8 LED matrix and five-button joystick. Raspberry Pi Zero W. Single-board computer with wireless and Bluetooth connectivity. The Sense HAT is an add-on board for Raspberry Pi.
Installation
- The Sense Hat installation on the Raspberry Pi is straightforward The Sense HAT has a GPIO connector that slot into all the pins, so you don’t have to think on where to plug it. Start with the Raspberry Pi off (unplug the power cable) Then, put the Sense Hat on the GPIO pins and push it gently to connect it; Finally, start again your Raspberry Pi.
- Specifications 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.
In order to work correctly, the Sense HAT requires an up-to-date kernel, I2C to be enabled, and a few libraries to get started.
- Ensure your APT package list is up-to-date:
- Next, install the sense-hat package which will ensure the kernel is up-to-date, enable I2C, and install the necessary libraries and programs:
- Finally, a reboot may be required if I2C was disabled or the kernel was not up-to-date prior to the install:
Hardware
The schematics can be found here.
Software overview
After installation, example code can be found under
/usr/src/sense-hat/examples
.These can be copied to the user's home directory by running
cp /usr/src/sense-hat/examples ~/ -a
.The C/C++ examples can be compiled by running
make
in the appropriate directory.The RTIMULibDrive11 example comes pre-compiled to help ensure everything works as intended. It can be launched by running
RTIMULibDrive11
and closed by pressing Ctrl+c
.Python sense-hat
sense-hat
is the officially supported library for the Sense HAT; it provides access to all of the on-board sensors and the LED matrix.Complete documentation can be found at pythonhosted.org/sense-hat.
RTIMULib
RTIMULib is a C++ and Python library that makes it easy to use 9-dof and 10-dof IMUs with embedded Linux systems. A pre-calibrated settings file is provided in
/etc/RTIMULib.ini
, which is also copied and used by sense-hat
. The included examples look for RTIMULib.ini
in the current working directory, so you may wish to copy the file there to get more accurate data.Other
LED matrix
The LED matrix is an RGB565 framebuffer with the id 'RPi-Sense FB'. The appropriate device node can be written to as a standard file or mmap-ed. The included 'snake' example shows how to access the framebuffer.
Joystick
The joystick comes up as an input event device named 'Raspberry Pi Sense HAT Joystick', mapped to the arrow keys and
Enter
. It should be supported by any library which is capable of handling inputs, or directly through the evdev interface. Suitable libraries include SDL, pygame and python-evdev. The included 'snake' example shows how to access the joystick directly.Calibration
Taken from this forum post.
Install the necessary software and run the calibration program as follows:
You will then see this menu:
Press lowercase
m
. The following message will then show; press any key to start.![Sense hat raspberry pi zero gravity Sense hat raspberry pi zero gravity](/uploads/1/1/9/5/119591219/565508313.jpg)
After it starts, you will see something similar to this scrolling up the screen:
Focus on the two lines at the very bottom of the screen, as these are the most recently posted measurements from the program.Now you have to move the Astro Pi around in every possible way you can think of. It helps if you unplug all non-essential cables to avoid clutter.
Try and get a complete circle in each of the pitch, roll and yaw axes. Take care not to accidentally eject the SD card while doing this. Spend a few minutes moving the Astro Pi, and stop when you find that the numbers are not changing anymore.
Now press lowercase
s
then lowercase x
to exit the program. If you run the ls
command now, you'll see a new RTIMULib.ini
file has been created.In addition to those steps, you can also do the ellipsoid fit by performing the steps above, but pressing
e
instead of m
.Maton serial numbers search. When you're done, copy the resulting
RTIMULib.ini
to /etc/ and remove the local copy in ~/.config/sense_hat/

These steps may not work on Raspberry Pi 2 Model B Rev 1.0 and Raspberry Pi 3 Model B boards. The firmware will take control of I2C0, causing the ID pins to be configured as inputs.
Raspberry Pi Zero Projects
- Enable I2C0 and I2C1 by adding the following line to
/boot/config.txt
: - Enter the following command to reboot:
- Download and build the flash tool:
