A pre-calibrated digital temperature and humidity sensor module designed for easy integration with Arduino, Raspberry Pi, Micro:bit, and other microcontrollers. The DHT11 provides accurate readings via a single-wire digital interface with no additional components required. This module features an integrated 8-bit microcontroller with factory-calibrated coefficients stored in OTP memory for reliable measurements. Low power consumption makes it ideal for battery-powered and IoT applications. Key Features Pre-Calibrated – Ready to use out of the box, no calibration needed Digital Output – Single-wire interface for easy connection Wide Voltage Range – Works with 3.3V and 5V systems Low Power – Only 40-50µA in standby mode Long-Term Stability – Calibration coefficients stored in OTP memory Includes Wiring Cable – Ready to connect Specifications Operating Voltage: 3.3-6V DC Measuring Current: 1-1.5mA Standby Current: 40-50µA Humidity Range: 0-100% RH Humidity Accuracy: ±2% RH Temperature Range: -40°C to 80°C Temperature Accuracy: ±0.5°C Interface: Single-wire digital Compatibility Arduino (all models) Raspberry Pi Micro:bit ESP8266 / ESP32 Intel Edison, Joule, Curie Any 3.3V or 5V microcontroller Ideal For Weather stations HVAC monitoring IoT environmental sensors Home automation Data logging projects Package Contents 1× DHT11 Sensor Module 1× Wire with Header Wiring Note: The yellow cable is GND (not signal).
