PLEASE NOTE: A new version of the PCB is being shipped going forward (REV C), but with the same functionality. The layout has changed slightly from what is shown in the image, but the mounting holes and Raspberry Pi Zero location remain the same.
This is an add-on board for the Raspberry Pi Zero which allows the DIY enthusiast to easily build a networked radiation monitor with a rich web-based UI. This is a fully open hardware and open source design. The tube provided with the board (if selected when purchased) is an SBM-20, which is quite sensitive. Clips on the board secure the Geiger-Muller tube for easy replacement. Note that a Geiger Tube or Raspberry Pi Zero W is not included with the product by default. If you'd like a tube and Raspberry Pi Zero W with SD card (preconfigured), please add these options.
This board was designed to create a network-enabled radiation monitoring solution. In the modern world, there are many potential radiation hazards which may pollute our environment, from power plants to nuclear weapons. The more citizens who take their own and their families safety seriously the better and safer the world is for all of us. Building your own radiation monitoring node with the Raspberry Pi Zero Geiger Counter and taking charge of knowing your environment can help with goal.
Using the Raspberry Pi Zero allows for a full-featured web interface using open source software running on the embedded Linux system.
This add-on board uses a simple microcontroller to control a high-voltage boost supply to generate the needed voltage across a Geiger-Muller tube. A discharge across the Geiger-Muller tube generates a pulse which is detected and counted by the Raspberry Pi Zero. The microcontroller is connected to the Raspberry Pi Zero's I2C bus, allowing control of the high-voltage supply by software on the Raspberry Pi Zero.
Many other designs use a 555 timer which is manually adjusted and free running, but which is much less flexible. This board allows for full control of the high-voltage boost supply from the Raspberry Pi.
The base price does not include a Raspberry Pi Zero, although a and socket and mounting hardware is provided. Any version of the Raspberry Pi Zero may be used (Raspberry Pi Zero W pictured for reference only.) If you'd like a Raspberry Pi Zero W and SD card pre-configured, please choose this as an option.
