DHT11 Temperature & Humidity Sensor Module – Digital Output

Description

DHT11 Temperature & Humidity Sensor Module – Digital Output, Ideal for IoT, Arduino, and Embedded Projects

The DHT11 Sensor Module is a compact and easy-to-use digital sensor designed for measuring ambient temperature and relative humidity. It is a must-have for anyone working on weather monitoring, smart agriculture, home automation, or IoT-based environmental sensing. Its low cost, decent accuracy, and digital output make it an ideal choice for beginners, hobbyists, students, and embedded system developers alike.

Unlike analog sensors, the DHT11 communicates using a single-wire digital signal, which simplifies wiring and ensures reliable data transfer without the need for complex analog-to-digital conversion. With its built-in microcontroller and pre-calibrated sensing components, it offers stable and consistent readings across various environmental conditions.

This sensor is commonly used with platforms like Arduino boards, Raspberry Pi, ESP8266, ESP32, and STM32 microcontrollers. It has wide support across software libraries and development frameworks, making it easy to integrate into both DIY and production projects.
