BoardPilotDHT11 temperature + humidity with ESP32
Supply 3.3-5 V
Bus ONEWIRE
Measures temperature, humidity
Pins and ESP32 wiring
| Pin | Role | ESP32 pin | Notes |
|---|---|---|---|
| VCC | Power | 3V3 | |
| DATA | One-wire data | D25 | Needs a 10 kΩ pull-up (already on 3-pin modules; 3-pin module order varies, read the labels) |
| NC | Not wired to the ESP32 | — | Not connected |
| GND | Ground | GND |
Suggested wiring for the 30-pin ESP32 DevKit, avoiding flash, input-only and strapping pins. BoardPilot checks it for you as you wire.
