DHT11 Humidity and Temperature Sensor Module

The DHT11 Humidity and Temperature Sensor Module is a compact digital sensor designed to accurately measure ambient temperature and relative humidity. It combines a calibrated humidity sensing element with an NTC temperature sensor and an integrated high-performance 8-bit microcontroller to provide reliable digital output. The sensor delivers stable and accurate measurements without requiring additional signal conditioning, making it ideal for environmental monitoring and embedded system applications.

The module operates using a single-wire digital communication interface, allowing simple and direct connection to a wide range of microcontrollers and development boards. It operates from a 3.3V to 5V DC power supply, making it compatible with Arduino, ESP32, ESP8266, Raspberry Pi, STM32, PIC, AVR, and other microcontroller platforms. The onboard circuitry includes the necessary pull-up resistor and indicator components, enabling quick and hassle-free integration into electronic projects.

The DHT11 Sensor Module measures temperatures from 0°C to 50°C with typical accuracy of ±2°C, and relative humidity from 20% to 90% RH with typical accuracy of ±5% RH. Its factory calibration ensures consistent performance, while low power consumption makes it suitable for battery-powered and IoT applications.

The DHT11 Humidity and Temperature Sensor Module is widely used in weather stations, home automation systems, smart agriculture, greenhouse monitoring, HVAC control, environmental monitoring, IoT devices, data logging systems, educational laboratories, robotics, and DIY electronics projects where reliable temperature and humidity measurement is required.
