This circuit consists mainly of the following components: a solar cell, a DC pump, a 555 timer, and an LM311 comparator. It worked well and was also very efficient, requiring only power from the solar cell rather than a battery. Read more
A solar-powered water pump circuit for a place with no power outlet, with a battery. We’ll learn how to use a MOSFET instead of a relay, as well as the NE555 timer circuit. Read more
This is simple Solar plant watering alarm circuit. It will sound alarms when the soil is dry. The trees have died. It the solar sell is 6V DC power supply Read more
This is Outdoor solar lights circuits made by my son, at day solar charge to battery then night LED light up without AC line, Relay control the solar current […] Read more
Previously, we had built the Automatic Solar Light circuit and had been using it for many months. It has fair efficiency for everyday lighting. But this circuit has two problems: a dim light level and batteries that are hard to find and quite expensive. But now my daughter has built this Simple solar light circuit … Read more
