The ESP8266 microcontroller is a favorite among makers for creating affordable, Wi-Fi-enabled sensor projects. Pairing it with a DHT22 temperature and humidity sensor is one of the easiest ways to get ...

We've all heard that "if you want something done right, you have to do it yourself." And that’s usually fine when it comes to ...

Abstract: This paper proposed a self-contained IoT sensor module which includes sensor for collecting various information, micro-computer and multiple solar panels for realizing dynamic cost reduction ...

Large photovoltaic power plants often comprise tens of thousands of modules and components. Whenever individual solar modules malfunction, intact bypass diodes can contain a strong power loss in the ...

Abstract: We developed a compact sensor module for hydroponics that measures the nutrient concentration and water level using simple oscillator circuits. Oscillation frequencies are measured and are ...
