![]() Place the sensor on your breadboard next to the ESP32. Begin by placing the ESP32 on your breadboard, making sure that each side of the board is on a different side of the breadboard. Wiring a DHT11/DHT22 sensor to an ESP32Ĭonnecting a DHT11/DHT22 sensor to an ESP32 is pretty easy. As a result, the internal temperature sensor is only appropriate for applications that detect temperature changes rather than absolute temperatures. Temperature measurements are also affected by the heat generated by the Wi-Fi circuitry. This temperature sensor produces a voltage proportional to temperature, which is then converted to digital form by an internal analog-to-digital converter.Īccording to the ESP32 datasheet, the issue with this temperature sensor is that the offset varies from chip to chip due to process variation. ![]() ![]() The ESP32 does, in fact, include a temperature sensor with a temperature range of -40☌ to 125☌. The ESP32 has a built-in temperature sensor, so why not use that? ![]()
