DHT11 Temperature and Humidity Sensor

ESP8266 ESP-03 WIFI Module

The DHT11 is a commonly used Temperature and humidity sensor that comes with a dedicated NTC to measure temperature and an 8-bit microcontroller to output the values of temperature and humidity as serial data.

The DHT-11 Digital Temperature and Humidity Sensor is a compact and reliable sensor that can measure temperature and humidity with high accuracy. This sensor features a single-wire interface, making it easy to integrate with microcontrollers and other electronics projects. The DHT-11 has a temperature measurement range of 0°C to 50°C with an accuracy of ±2°C, and a humidity measurement range of 20% to 80% RH with an accuracy of ±5% RH. It is ideal for applications that require temperature and humidity monitoring, such as weather stations, greenhouses, and HVAC systems. With its low cost and high performance, the DHT-11 is an excellent choice for any electronics project that requires temperature and humidity sensing.
