This is based on the wireless serial transceiver module, ESP8266 SoC.The SOC integrates TCP / IP protocol stack.It is a TTL serial communication interface, its parameters can be set by AT commands. It is widely used in networking, smart home projects when it is connected to wireless routers. It can be used for remote monitoring of home appliances, bedroom temperature and humidity, and home appliances and smart cars controlled by mobile phones.
Arduino's UNO R3 and compatible boards can be connected directly to this module.
