DHT11 Sensor Module

Product overview

The DHT11 is a low-cost digital temperature and humidity sensor module commonly used in electronic projects. It's part of the DHT series, which also includes the DHT22 (AM2302). The DHT11 is known for its simplicity and ease of use, making it popular in hobbyist and educational projects.

Key Features :

Measurement Range: The DHT11 can measure temperature in the range of 0°C to 50°C with a resolution of 1°C. It can measure humidity in the range of 20% to 90% with a resolution of 1%.

Digital Output: The DHT11 provides a digital output, making it easy to interface with microcontrollers such as Arduino.

Communication Protocol: It communicates over a single wire using a proprietary protocol. Libraries are available for various platforms, simplifying integration into projects.

Accuracy: The DHT11 has a moderate accuracy level. Temperature accuracy is typically ±2°C, and humidity accuracy is around ±5%.

Power Supply: The sensor usually operates on a voltage of 3.3V to 5V.

Response Time: The DHT11 has a response time of around 2 seconds, providing temperature and humidity readings at a relatively slow rate.
