Watering when the soil is dry, airing the greenhouse when it is hot, knowing when the tank is nearly empty. 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.
The probe in the pot decides, the pump gives water for a few seconds.
Parts: Soil moisture probe, MOSFET driver, 12 V pumpKeeps the data over time
The request it sends: «When the soil is dry, run the pump for 5 seconds, then wait a minute before checking again»
Build it in the IDE →Over 28 °C the fan starts, and you keep the temperatures' history.
Parts: BME280 climate sensor, RelayKeeps the data over time
The request it sends: «In the greenhouse: turn the fan on the relay on over 28 degrees, off under 25, and log the temperature every 5 minutes»
Build it in the IDE →The level sensor feels the water is low and sounds.
Parts: Water level sensor, Buzzer
The request it sends: «When the level sensor says the tank is nearly empty, beep three times every minute»
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.
