This next project is great for those who enjoy firing up the grill on the weekends and cooking under the open sky. There are a few different Raspberry Pi-based automated BBQ controllers out there. Tempiture and PitmasterPi are both popular options, but one of the more trusted operating systems is called HeaterMeter.
HeaterMeter allows you to monitor and control BBQ smokers and grills on the Raspberry Pi itself, or through web-based automation. HeaterMeter uses a PID algorithm to automatically control pit temperature, adjust blower speed, and monitor up to four probes at the same time. You probably don’t need something like this to grill a few burgers and dogs, but it could be a real lifesaver for meals like brisket that can take hours to cook.
The DIY approach to making one of these controllers involves making a 3D-printed enclosure and attaching an LCD display, sensor inputs, power adapter, SD card, wireless USB adapter (if the Pi you have doesn’t come with built-in wireless connectivity), a control output, and several other accessories. But those who don’t have access to a 3D printer or who simply don’t want to build their own from scratch can purchase fully assembled kits too.
