This instructable shows how to build a rather special pool sensor measuring the pool temperature and transmitting it via WiFi to Blynk App and to a MQTT broker. I call it the “Crocodile Solar Pool Sensor”. It uses the Arduino programming environment and an ESP8266 board (Wemos D1 mini pro). What’s so special about this project? […]
If you’ve installed solar panels on a camper van to provide you with electricity on your camping trip or at home to supplement your electricity usage or take your home completely off grid then you probably know that the panels work the best when they are aligned directly towards the sun. This sounds simple enough,

Introductions of single axis solar tracker: A commonly favored Arduino project is a solar tracker system that follows the intensity of sunlight. It is divided into two primary categories: the single-axis solar tracker and the dual-axis solar tracker. The solar tracker with only one axis is operated by one motor, enabling movement in two directions.

1. Introduction (1) Purpose A conventional solar panel typically converts only 30 to 40 percent of incident solar irradiation into electrical energy. To ensure a consistent output, an automated system capable of continuously adjusting the solar panel’s orientation is necessary. Addressing this need, the Sun Tracking System (STS) was developed as a prototype solution. This

Long battery-life and Low power consumption are usually top on the list of requirements for most hardware devices these days, as the weariness of having to constantly charge a device continues to have significant effect on customers’ choice. Asides from consumer applications, another reason fueling this demand is the growth in the deployment of IoT

I always wanted to make a PCB and this is my first professional circuit board attempt. So before you decide to start this project you should know there could be some mistakes or it could be more reliable and compact. This design is not the most efficient and cheapest way to make a DIY MPPT

Researchers at Northern Illinois University and the U.S. Department of Energy’s (DOE) National Renewable Energy Laboratory (NREL) in Golden, Colorado, reported in the journal Nature on a potential breakthrough in the development of hybrid perovskite solar cells. Considered rising stars in the field of solar energy, perovskite solar cells convert light into electricity. They’re potentially cheaper and simpler to produce than
SCIENTISTS DEVELOP SAFER LEAD-BASED PEROVSKITE SOLAR CELL STRUCTURE Continue Reading
This project is an update of my original Peak Power Tracker Battery Charger Project. It is designed to control a 12V solar panel charging a 12V lead acid battery. The updated version of this project uses the Arduino Duemilanove development board (from www.sparkfun.com) as the basis for the project. Then I used the Arduino Protoshield
For my first IoT project I wanted to build a Weather Station and send the data to data.sparkfun.com. Small correction, when I decided to open my account in Sparkfun, they were not accepting more connections, so I choose another IoT data collector thingspeak.com. Continuing… The system will be placed on my balcony and will retrieve temperature,
Leveraging the natural adsorption–desorption exchange of water molecules from ambient air at the interface of a nanoporous mesh of protein nanowires, a team of researchers from the University of Massachusetts has demonstrated a durable form of energy harvesting that could potentially compete with solar cells on volumetric power density.
