The WeMos D1 Mini family of boards is one of the latest additions to the ESP8266-based IoT ecosystem. The WeMos D1 Mini DHT-11 Temperature/Humidity Sensor Shield includes the popular sensor for measuring temperature and relative humidity locally.
The WeMos D1 Mini DHT-11 Temperature/Humidity Sensor Shield is designed so that pin D4 on the WeMos D1 Mini v2 board is connected to the data pin of the sensor. This means that you'll need to configure your software to use pin D4. There are plenty of existing libraries to work with this sensor especially uf you're using the Arduino Software. This inexpensive sensor is a great way to get temperature and humidity data, as it only uses one pin from the microcontroller or SoC.
What makes the WeMos family of development boards for the ESP8266 great is the availability of stackable, plug-and-play shields such as this WeMos D1 Mini DHT-11 Temperature/Humidity Sensor Shield. Without much fuss, it's very easy to connect, control, and monitor a wide variety of electronic components to the ESP8266. The WeMos family is a great solution for building projects quickly using the ESP8266 SoC.
Different users have different applications for the WeMos shields, thus we've found that the easiest way to please everyone is to ship the boards with the headers unsoldered. Each board in this kit includes a pair of Male, Female, Long Female pin headers for you to choose. Soldering is required for installing the header pins!
DHT-11 measurement range: 20~95%RH; 0~50°C DHT-11 data pin connected to pin D4 Breaks out all the WeMos pins for easy access when stacked on top of/below the WeMos D1 Mini v2
