Solar Soil Moisture Meter // Becky Stern

Hi, it’s Becky. Today we’re making a solar powered soil moisture monitor. It uses an ESP8266 wifi microcontroller running some low power Arduino code, and everything’s waterproof so it can be left outside. Let’s get started. You’ll need a solar battery charging board and ESP8266 breakout such as the NodeMCU or Huzzah, as well as […]

Review Solar Panel 10W Arduino & Node-RED – Revision Panel Solar 10W : PDAControl

Some weeks ago I posted a Dashboard in Emoncms if you want to see the full dashboard It is in the description of the video Test with white light “led” We will validate the tests with Arduino In previous tutorials we made Voltage measurements with Arduino Accurate and safe Arduino sends data to Node-RED by […]

#142 Solar Power for the ESP8266, Arduino, etc.

Grüezi YouTubers. Here is the guy with the Swiss accent. With a new episode around sensors and microcontrollers. We all have our gadgets, and all of them need some electricity. Usually, we use batteries or a power supply. Today I will start a small project to use solar energy to power our devices during the […]

Cheap 5V solar panel power test

In this video we go to test this cheap Chinese solar panel. Item size is 26 x 14 cm Weight is only 102 g and it’s very thin (about 1 mm) Panel contains voltage regulator which output should be 5V Maximal output current shoud be 1,2 A Let’s test the voltage Open-circuit voltage is 5.06 […]
