In this image, we have outlined the setup for our temperature and humidity monitoring using the DHT11 sensor. The DHT11 is interfaced with the ESP8266 microcontroller, with the sensor’s data pin connected to the ESP8266's D1 pin. This allows the microcontroller to read the environmental data captured by the sensor. Power is supplied to the DHT11 through the VCC pin, and the ground is connected to the GND pin as indicated on the sensor's pinout. It's essential to consult the sensor's documentation to accurately identify the pin configuration and ensure correct connections for reliable readings.
