MakerFocus 2pcs ESP8266 ESP-01 Serial Wireless WiFi Transceiver Receiver Module 1MB SPI Flash
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.
