Water Level Indicator Kit With Full And Low Tank Alarm | Zero Corrosion Design
This circuit can be used as a water level indicator with a full tank alarm or low tank alarm or both. It can also be customized to auto stop the alarm after few seconds in low tank alarm.
Zero corrossion design: We can use any metals as sensors. There is no need to use costly float switches. As there is no reaction inside the water, there is no corrosion of metals. This can be used in drinking water tanks too!
