【Solicitation Order】ESP8266 WiFi Channel Analyzer

Project Description

Use ESP8266 to scan nearby WiFi, display the number of WiFi in each channel and the signal strength of different WiFi on the screen, and give recommended channels.

Project function introduction

• Powered by lithium batteries, easy to carry;

• Use ESP8266 as the main control to reduce the use of peripheral circuits;

• The screen uses a 1.8' TFT color screen and the driver is ST7735;

• Onboard automatic download circuit facilitates later debugging;

• • -

Precautions

Arduino needs to install the ESP8266 development board. The additional development board address is http://arduino.esp8266.com/stable/package_esp8266com_index.json.     After installation, select the corresponding development board.

At the same time, you also need to install the Adafruit_GFX and Adafruit_ST7735 libraries, and then you can compile and use them.

Different ST7735 screens have different pin definitions, so you need to pay attention when using them. If the interface is inconsistent, modify the circuit by yourself. Due to the display size limit of 128x160, the display will be blurry when there are too many WiFi connections. To change to a larger screen, you need to modify the screen driver library in the program.
