The sensor itself is on the front part of the metal tube. There are three wires. The red is positive, black is ground and blue is the signal. The sensor outputs a low frequency PWM signal which can be easily used with a microcontroller. After you successfully salvaged the sensor from its smelly home, you are left with something like this:.
Especially the red wire is very short because it only connects to the positive side of the battery. I decided to resolder the connections using jumper wires. If you don't trust your soldering skills, you should solder the jumper wires onto the existing wiring so leave it as long as possible. Be careful, the existing wires are likely to break. Luckily, I had some tubing with the right inner diameter lying around. It should also be possible to use heat shrink to mount the sensor on the case.
In ether case, you need app. The currently used sensor only detects a vacuum. Another sensor could detect both directions of the air flow. The BMP with a filter might be suitable mine was a bit too sensitive for humidity..

The used joystick requires the ability to slightly move the head. Other devices, like they are used for e. Track Points, might allow to operate the device only by using the lips or the tongue. The USB connection could be replaced by Bluetooth or another kind of wireless connection.
The firmware only supports a mouse emulation for the moment. Keyboard or gamepad emulation could be implemented in the future. A single PCB solution would result in a much smaller, more professional and easier-to-build device. Unfortunately it is a bit inconvenient to clean the mouthpiece. I would be happy if someone would like to contribute in any way to this project. The design is modular. Every part can be modified to fit your needs. If you have questions, please don't hesitate to contact me. If someone needs help with the electronics for a project that enables people to play games, surf the internet or simply helps with the everyday life, you are also welcome to contact me.

Summary About This project was intended to prove if it is possible to build a pointing device mouse for people with disabilities for under 20 USD, using only components which are widely available as well as a 3D printer. Functionality The user moves the cursor by using a mouthpiece which basically works like a joystick. Bill Of Material 3D printed parts 1x mouthpiece should be printed with non-toxic material 1x front 1x joystick mount 1x cable box 1x back.
