Good morning! One of my pandemic projects was a simple temp/humidity sensor with a microcontroller, DHT11 and LCD display in a 3D printed holder. Code is simple, snips probably come from Drone Bot Workshop tutorials (thanks, Bill 🙂 ).
It sits on my desk quietly, until recently when it started to display odd characters. Happened 3 times in the last week. Of course powering it off/on "fixes" it.
I'll start troubleshooting, working from the sensor forward, but my philosophical question is really about how much lifespan can I expect from these components that cost only a few dollars?
Oh, this is what it is supposed to be displaying
Have a great Sunday!

I'm having a similar problem. I hooked up my DHT11 again after a while, and it only displays nan for the humidity and temperature.
