ESP-01 is a tiny and useful piece of hardware. It has a 32-bit MCU, 2.4GHz 802.11 b/g/n WiFi, 1MB flash memory, and several other useful embedded features. Such specifications allow us to use it for a variety of remote controlling/monitoring projects. In this article/video, I designed a circuit to monitor the temperature and control a Relay over the local WiFi. You only need to visit the IP address of the board in your computer/mobile phone browser.
To design the schematic and PCB, I used Altium Designer, embedded a DS18B20 sensor to sense the temperature, and a small 5V-10A Panasonic Relay to control an external device. You can power the board using a 5V USB Type-C cable, such as a mobile phone charger or a power bank. I paid attention to supply filtering and decoupling to ensure the stable operation of the device.
The webpage data is stored in the flash memory of the ESP-01 module. Ajax coding allows the temperature value to get updated every second, without any need to refresh the webpage. Similarly, you can control the state of the Relay anytime.

Hello my dear brother, I hope you can make a 3 phase inverter for us. You are very skilled at programming. I need it very much. Thank you.

Can you program it to have a "Set on/off temp" section...and turn it into a remote temp sensor thermostat?
