DFRobot Gravity DHT11 Digital Temperature & Humidity Sensor for Arduino

DFRobot Gravity DHT11 Digital Temperature & Humidity Sensor is a digital sensor module for Arduino that measures temperature from 0°C to 50°C and relative humidity from 20% to 90% RH. It provides digital readings for both temperature and humidity, supporting simple environmental sensing with Arduino microcontrollers.

Overview

The module integrates an 8-bit microcontroller with calibration coefficients stored in OTP memory to support consistent measurements. It uses a resistive humidity sensing element and an NTC thermistor for temperature measurement. The design includes full-range temperature compensation, low power consumption and long-term stability, along with fast response times and anti-interference capabilities.

Key Features

• Digital signal output with a transmission distance of up to 20 metres
• Part of the DFRobot Gravity series with a standard digital interface for connection to Arduino boards
• Temperature accuracy of ±2°C across the 0°C to 50°C range
• Humidity accuracy of ±5% RH across the 20% to 90% RH range
• Operating voltage from 3.3 V to 5 V DC
• Standard assembly structure with two 3 mm mounting holes spaced 5 mm apart
• Connector and immersion gold surface for corrosion resistance and electrical contact

Applications

The sensor is suitable for HVAC systems, meteorological stations, humidity regulators, dehumidifier testing, automotive projects and a range of automation and control systems. The module is intended for hobbyists, educators and engineers working on environmental monitoring with Arduino.
