== Summary ==<br />
The Sense HAT (C) is a Raspberry Pi expansion with onboard sensors for motion, environmental data, color and AD measurements.<br />

<br />
== Technical overview ==<br />
* Connects via the standard 40-pin Raspberry Pi GPIO header; uses I2C at a 3.3 V logic level.<br />
* Onboard IMU module QMI8658C (3-axis accelerometer + 3-axis gyroscope) and AK09918C (3-axis magnetometer), each with 16-bit resolution.<br />
* SHTC3 measures temperature (-30 to 100 °C, ±0.2 °C) and relative humidity (0–100 % rH, ±2 %).<br />
* LPS22HB pressure sensor: range 260–1260 hPa, accuracy ±0.025 hPa at room temperature, rates from 1 to 75 Hz.<br />
* TCS34087 color sensor with 4 channels (R, G, B, C) at 16 bits per channel.<br />
* SGM58031 4-channel 16-bit ADC for connecting external sensors through the breakout I2C pins.<br />
* I2C addresses of the onboard sensors are unique: SGM58031 = 0x48, QMI8658C = 0x6B, AK09918C = 0x0C, LPS22HB = 0x5C, SHTC3 = 0x70, TCS34087 = 0x29.<br />
* Raspberry Pi demo programs are located under /home/pi/Sense_HAT_C_Pi/RaspberryPi/... and run on Linux.<br />
<br />
'''Commands and examples – verify before use:''' <br />
<syntaxhighlight lang="text"><br />
sudo raspi-config<br />
sudo reboot<br />
cd /home/pi/Sense_HAT_C_Pi/RaspberryPi/IMU/bcm2835/<br />
sudo make clean && sudo make && sudo ./main<br />
cd /home/pi/Sense_HAT_C_Pi/RaspberryPi/IMU/python/<br />
sudo python IMU.py<br />
</syntaxhighlight><br />
<br />
== Notes and version constraints ==<br />
* On Bookworm systems only the lgpio library is available; bcm2835 and wiringPi cannot be installed or used.<br />
* Mixing bcm2835/wiringPi/Python may cause abnormal GPIO header behavior; the fix is to reboot the Raspberry Pi.<br />
* STM32 demos require a correct serial connection on USART2 (PA2 TXD, PA3 RXD) with a 115200 baud rate.<br />
* Some steps are version-sensitive (e.g., installing wiringPi depending on the system release); verify the current system version before running them.<br />
* All statements rely solely on the supplied source text; additional compatibility, safety, or warranty claims were intentionally omitted.<br />
