A compact portable power supply that can be charged using built-in solar panels or via a USB port.
An open ESP32-S3 camera in a hanging solar trap photographs fruit flies over 4G; OpenCV 5 counts them and a person approves the next move.
Off-grid ESP32 system that auto-waters crops when soil is dry using solar+battery, with phone monitoring.
A time switching battery powered solar charged circuit, used to power an Arduino Uno and some peripherals.
Fun and easy green robot! Build a sun tracking solar array in under an hour. Bonus: charge your phone with free clean energy!
Solar tracking photovoltaic (dual axis) that follows the sun, using LDR sensors and two DC motors.
Quickstart guide to start with #NodeMCU on the #ESP8266 Thing, hacking to become a ultra-low power, solar power only driven #SENSableTHING
Microcontroller based Solar PV System's charge controller, inverter, PowerBank & LED lamp with menu-based navigation system on LCD display
There are many charge controllers available, but ordinary cheap ones are not efficient enough to use with maximum power from solar panels.
A solar panel that can rotate in two axis either automatically using four light sensors, either manually with the aid of two potentiometers.
Use Tracer MPPT (and others) controller's RS485 data link to generate cool statistics live on your phone.
This was an unexpected child, Lets take a look a real world transition from ESP8266 code. What changes when you swap horses?
A solar-powered temperature and humidity monitoring system for compost.
Combines basic woodworking (house/feeder) with a Pi Zero W/cam powered by batteries/solar & turned on/off w/ an ATtiny85 and BH1750.
Get the temperature, humidity and pressure, and display them over the internet; everything is powered by the sun.
Fresh, organic food is important! Grow your own in unused space and take care of it remotely. Plants and smarts are powered by the sun!
This system is to get 100% sun energy. In this system solar panel will move in the direction of sun from sun rise to sun set.
A solar-powered, outdoor air quality monitor that transmits data over LoRaWAN networks like The Things Network and Helium
Get your essential appliances off the grid with just one solar panel
This moisture sensor sends hourly updates to Ubidots and Pushover, and runs for years on solar power.
This IoT prototype performs two functions: 1) Theft prevention and 2) Maintenance Indication of solar panel using LinkIt ONE and Sensors
Measure wind, rain, temperature, humidity, and light in remote locations using ThingSpeak, Particle, and the Sentient Things IoT Node.
I use an electric valve, temperature sensors with WiFi connectivity to control and monitor optimal usage of solar energy.
Using two LDRs to get intensities in two direction and then comparing those intensities will rotate the servo motor.
