Temperature loggers to leave at the customer's, supply and return compared, CO2 warnings and extractors that start with humidity. Describe them in words, try them in the simulator and build them on an ESP32 board, without writing code.
Start with your work →Free, in the browser: try it in the simulator first, then buy only the parts it needs.
Temperature and humidity every minute, with the graph and the file to send.
Parts: SHT31 temperature and humidity sensor, SSD1306 OLED screenKeeps the data over time
The request it sends: «Log the room's temperature and humidity every minute and show them on the screen, so I can see the graph over the days»
Build it in the IDE →Two probes and the difference on the screen: you see at once if the unit performs.
Parts: DS18B20 waterproof probe, SSD1306 OLED screenKeeps the data over time
The request it sends: «Two temperature probes, one on the air conditioner's supply and one on its return: show both temperatures and the difference on the screen»
Build it in the IDE →Measures CO2: a green light, then red and a sound over the limit.
Parts: SCD40 CO2 sensor, LED, Buzzer
The request it sends: «Measure the room's CO2: green LED under 1000 ppm, red LED and a sound over 1000 ppm»
Build it in the IDE →On over 70%, off under 60%.
Parts: SHT31 temperature and humidity sensor, Relay
The request it sends: «Turn the extractor on the relay on when humidity goes over 70% and off under 60%»
Build it in the IDE →Write what you need in your own words: the assistant proposes the project and tells you if something cannot be done.
