This article is a client/server programming example for a wireless network weather station (Client/Server Programming for Weather Stations via Wireless Networking) using two esp32 microcontrollers communicate over a wireless network. By setting the DHT22 and LDR sensor installed as a server working in AP mode and another esp32 microcontroller board working as a client and media via a custom port to read the temperature, humidity and digital values ​​obtained from the LDR sensor as shown in Figure 1.
