ESP-12F ESP8266 NodeMCU Development Board with DHT11 Temperature Humidity Sensor

ESP-12F ESP8266 NodeMCU Development Board with DHT11 Temperature Humidity Sensor Features: 1.The ESP8266 NodeMCU board has all the functionality of a traditional ESP8266 module with the exact same dimensions and peripheral ports, seamlessly integrating with the DHT-11 temperature and humidity sensor, reducing the need for complex wiring and breadboarding. 2. Pair with the popular DHT11 temperature and humidity sensor. The DHT-11 is a commonly used temperature and humidity sensor equipped with a dedicated NTC for temperature measurement and an 8-bit microcontroller for outputting temperature and humidity values as serial data. 3. Easy to use, the module can also be connected to the 3.7V lithium battery to continue to run offline after the completion of programming and development. 4. Using a more mature and stable serial chip CH340C, stable performance, equipped with ESP-12F module built-in W-Fi and deep sleep operation. 5. The board is an excellent choice for various Internet of Things (loT) projects. Suitable for loT project learning, building internet weather stations, smart home warehouse environment monitoring cold storage monitoring and other similar applications. Product Description: This module has a popular temperature and humidity sensor DHT11 (data foot connected to the module of the D2 pin), depicted with the WIFI module ESP-12F, a more mature and stable serial chip CH340C, there is a reliable charging management chip, and with the default factory test firmware, connected to the computer can be realized through the serial assistant software to achieve the real-time transmission of temperature and humidity data (9600 baud rate), the module programmer After the development is completed, it can also be connected to a 3.7V lithium battery to continue offline operation.
