HF3 – WiFi RTD Meat Smoker Temperature Transmitter

許風三號

Hui Gardens HF3 WiFi RTD meat smoker temperature transmitter prototype was created to allow my wife and I to monitor the temperature of her smoking creation without going out into the cold and having to manually look at the temperature display. It also allows remote monitoring should we need to run out on a quick errand.

The Hui Gardens HF3 is housed inside a Pelican 1010 case to protect it from the elements since this is meant to be outside where her Traeger smoker is. I found that the temperature probes supplied with her Traeger smoker is a PT1000 2 wire RTD with a 3.5mm aux plug on the end. That’s easy enough, I can work with that. The brains of the HF3 is an Arduino UNO Rev 3 with a WiFi shield and RTD amplifier. Powered by 4x AA batteries that fits inside the housing, I’ve run the Hui Gardens HF3 in the cold for over 12 hours. The HF3 sends the temperature data over WiFi to http://www.huigardens.com/hf3 allowing for remote monitoring.

To allow for easy hanging of the HF3 WiFi temperature transmitter using the supplied carabiner of the Pelican 1010 case, the temperature probe input is located at the bottom to help in inclement weather since it’s facing down.
