ESP32 Soil Moisture & DHT22 Circuit Design
Thought for 3 sec
Your project is currently empty — there are no components or nets in the schematic. I can’t execute the circuit creation right now because there are no available ACUs for AI actions.
What remains to be done:
- Add an ESP32 module/dev board symbol.
- Add connectors for the soil moisture sensor and DHT22.
- Add a 3.3 V power rail and GND wiring.
- Add a pull-up resistor for the DHT22 data line, typically 4.7 kΩ–10 kΩ to 3.3 V.
- Assign ESP32 GPIO pins for:
- DHT22 DATA
- Soil moisture sensor analog output
- Optionally add USB/battery power, regulator, protection, and headers depending on how you want to power it.
Suggested default wiring:
- DHT22 VCC → 3.3 V
- DHT22 GND → GND
- DHT22 DATA → ESP32 GPIO4 with 10 kΩ pull-up to 3.3 V
- Soil sensor VCC → 3.3 V
- Soil sensor GND → GND
- Soil sensor AO → ESP32 ADC pin, for example GPIO34
Once ACUs are available, I can build the schematic directly in Flux.
