Wifi signal strength indication using esp8266

This is a fun project. Rather a very simple project. I am using the RSSI level checking of the esp8266 chip to monitor the signal strength of the surrounding wi-fi signals. There are very few applications that i can think using this. You can check where the wi-fi signal is strong in a public place and […]

3.3 volt receiver signal level Interface board for esp8266-01

In my previous attempt at designing this board here. It was good. But to make the pcb smaller. I redesigned the pcb, i shifted some component here and there. This PCB contains a 3.3v level shifter at the receiver pin. Here are the schematics and pcb layout. Etching time : 1 hour and 20 minutes […]

Interfacing board of esp8266 to 5V microcontroller

Esp8266 runs on 3.3V and most microcontrollers run on 5v . The voltage difference can cause problems in communication or in the worst case it can burnout the esp8266.  So to address this probelm i created this simple interfacing pcb. 3d rendering of interfacing pcb Schematics and PCB Layout

Industrial Automation Using Internet of Things

The system will automatically monitor the industrial applications and generate alerts/alarms or take intelligent decisions using concept of IOT. The monitoring and controlling of the industrial automation is done through atmega32 microcontroller. The communication through the internet is done with the help of ESP8266 module. All the sensor data is collected and sent to the […]
