Thermometre esp8266
Webb9 juni 2024 · The ESP8266 ADC is not really a very good one for instrumentation purposes. I believe it's not very linear (especially for voltages near 0V) and the internal reference voltage might be +/-10% or worse tolerance- loosely specified (with no accuracy limits that I can see, kind of a "bonus" functionality that you shouldn't depend on too much for … WebbIf you want to monitor some remote temperatures this Instructable will show you can do this by using some ESP8266 modules, MQTT (with a broker), LCD screen (for local monitoring), home-assistant (for local and remote monitoring), and of cause some temperature sensors (I use DS18b20 as they are pretty good and cheap enough)
