I need a component to heat a box up to 80°C. Any recommendations?
Morning guys, I'm working on a project with my friend that requires heating the inside of a box up to a maximum of 80°C. Does anyone know of a "heating" component that could be used? I tried the Peltier module before realizing it wasn't suitable. The goal of the project is to maintain the inside of the box between 60°C and 80°C for several hours. The ventilation, timer, and temperature measurement parts are already completed. Everything is controlled by an 8266 and powered by an external power supply (I was thinking via USB-C, but it depends on the heating module if it requires more than 5V). Thanks.

I don't have a specific part to recommend. However, I'd look at something qualified for automotive or industrial as they are specified to operate up to 105°C or 125°C. Consumer parts are only good to 85°C, so you may find they burn out. Best thing is to try a few and see what works. Also be aware of thermal runaway - if I remember correctly, as the device heats up, its resistance drop, causing more current to flow, which causes the resistance to drop further, resulting in more current flow... Good luck!
