• The DHT11 Temperature and Humidity Sensor Module is a reliable, low-cost digital sensor widely used in DIY electronics, weather stations, and IoT applications. This compact module combines a capacitive humidity sensor and a thermistor to measure both relative humidity and ambient temperature with good accuracy for non-critical applications.
• With a simple 4-pin interface (VCC, DATA, NC, GND), it connects easily to microcontrollers like Arduino, ESP8266, ESP32, and Raspberry Pi. The single-bus digital output simplifies integration—no need for analog-to-digital conversion. The module comes pre-calibrated and includes a jumper cable for instant plug-and-play use.
• Ideal for home automation, greenhouse monitoring, HVAC systems, and educational projects. Though not as precise as DHT22 or SHT series, the DHT11 offers excellent value for hobbyists and beginners.
