The basic design idea is to set two ports of the MCU for water level detection, one port for automatic/manual mode switch selection, and two ports for visual status indication. From the reading of the ...

Fluid level sensing with reed switches involves a fixed column of reed switches as high as the potential fluid level change, actuated by a floating magnet. These might not be as simple as they first ...

Description of water sensor: in most houses, water is first stored in an underground tank (UGT) and from there it is pumped up to the overhead tank (OHT) located on the roof. People generally switch ...

As the top sensor goes low (water above level C), the CLR signal is activated and the output of the flipflop is low. This allows Q1 to turn on and activate a triac or relay for the pump.

The system isn’t automatic and requires the home owner to manually switch the pump on and off. [Raikut] made this process a lot easier by designing an LED bar indicator to monitor the water level.

In 1964, OKI originally started manufacturing reed switches for switching equipment, and in 1996, OKI established OKI Sensor Device as a separate reed switch business company. Leveraging advanced ...
