A NodeMCU with 3 DS18B20 monitors the temperatures (T[o, T[u]) of a storage tank, heated by a combination of oil boiler, wood boiler and solar panels, the temperature of the wood boiler (T[HV]), and the temperature of the exhaust gas (T[Ag].
This an arduino based weather monitor station. It measures 5 different weather variables: temperature, wind speed, rainfall, illuminance and humidity. The Weather Station updates every 5 minutes to ThingSpeak.
Current sampling on electric kiln provides a 'signature' curve for each firing, enabling remote monitoring with minimal resources.
Platform: ESP32 (NodeMCU).
Live when firing in progress, otherwise last finished firing.
