The DHT11 is a low-cost digital humidity and temperature sensor renowned for its high reliability and long-term stability. It features a capacitive humidity sensor and a thermistor to measure the surrounding air, providing accurate digital output without requiring analog input pins. Its ease of use, supported by readily available libraries and sample codes, makes it an ideal choice for interfacing with microcontrollers like Arduino and Raspberry Pi. The module includes a built-in pull-up resistor, simplifying connectivity with just three necessary connections: Vcc, Gnd, and Output. This sensor is perfect for a wide range of applications requiring reliable and stable humidity and temperature monitoring.
