Solar Water Pump Circuit using Battery and MOSFET
In my earlier article I showed about solar water pump circuit using relay. That design works, but relay makes clicking sound and relay contacts can burn after long use. So now here is the new version. This project is Solar Water Pump Circuit using Battery and MOSFET instead of relay. MOSFET has no moving parts, […]
Solar Water Pump Circuit using Battery and Relay
This project is about Solar Water Pump Circuit using Battery and Relay. It uses one 18V 20W solar panel, two small 12V batteries, one relay and diodes. The circuit can run a 12V DC water pump. Battery stores power from solar panel and relay controls when pump run. It is a very simple circuit and […]
DIY Water Level Monitoring Circuit
DIY Water Level Monitoring Circuit is good for tank or reservoir. It use IC 555 timer in astable mode and make repeated signal. When water reaches a set level then buzzer turns ON. The circuit helps to stop water overflow and is useful in home, factory and farm. Circuit Working: Parts List: Component Quantity Resistors […]
Water Level Controller Circuit using IC 555
We can make simple Water Level Controller Circuit using IC 555 for our tank. It stop pump when tank is full and start again when water is low. We can change some parts to match our tank size and water level. Circuit Working: Parts List: Category Description Quantity Resistors 1k 1/4 watt 1 100k 1/4 […]
Header Tank Water Level Controller Circuit
This Header Tank Water Level Controller Circuit control water level in header tank. It stops motor when tank is full and start motor when tank is empty. It saves water and save electricity. There is no need to watch tank every time. Circuit works automatic with sensor in tank. Circuit Working: Parts List: Category Description […]
