This module to ESP8266 as the master, DHT11 for the temperature and humidity sensor. ESP8266 collection environment temperature and cooling upload to the server.
ESP8266 has powerful on-board processing and storage capabilities that allow it to be integrated with the sensors and other application specific devices through its GPIOs with minimal development up-front and minimal loading during runtime. Its high degree of on-chip integration allows for minimal external circuitry, and the entire solution, including front-end module, is designed to occupy minimal PCB area.
Can be used as a moisture and humidity collection node for intelligent home or IOT projects.
