Interfacing DHT11 with ESP32: A Step-by-Step Guide
Understanding the DHT11 Sensor The DHT11 sensor is a basic, low-cost digital sensor for sensing temperature and humidity. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air and provides a digital signal on the data pin. Wiring the DHT11 to the ESP32 The DHT11 sensor has four pins, but only […]
