Raspberry Pi Pico Monitors Pellet Smoker’s Hopper Level with Web App

For those of us in the northern hemisphere, summer is still in full swing. If you’re still planning a summer bash or two before fall hits, you might want to take a look at this awesome pellet smoker hopper level monitor created by maker and developer Joe Pecsi. Using our favorite microcontroller, the Raspberry Pi Pico, he’s able to monitor his pellet smoker’s hopper level and keep track of it with a mobile app. 

The concept is simple but also a super effective way to monitor the pellet level in your smoker without having to get up and check. It relies on an ultrasonic sensor to measure the pellet level which is then automatically reported through a web-based app. This can be checked from any device with a browser like a PC or a smartphone.
