This is an esp8266 based cat monitoring project. Monitors food and water bowl visits and litter box visit durations. Plots real time data for visits as well as daily totals. Click on More Information to visit and follow Muffin's Twitter @MyCatStats.
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.
