Water Sensor Switch Circuit
Create pcb skip step if using proto board.
Water sensor switch circuit. Make a simple circuit of a water sensor by using a few electrical devices. Check out the new water level sensor circuit. Rain alarm watertap leak detector water level sensor for bathroom water heaters wetness checker for flower pots and more. Water level indicator circuit liquid level sensor with alarm water level indicator using bc 547 transistor.
The schematic of the water sensor circuit that turns on a load when the water rises above a certain level causing the sense probe to touch the water. Bc 547 is an npn bipolar junction transistor that is used to amplify current to a certain level. Simple water sensor step 1. Here are some mock ups of.
Water switch sensor circuit. Don t trust just try it yourself. When the sense probe is out of the water an open circuit the voltage v probe is 5 v. 3 two 500 ohms resistor.
The voltage v probe at the comparator s inverting input depends on whether the sense probe is touching the water. 4 a 10kohms resistors. Connect to hho cell or any other water sensing probe. It switches on the pump when the water level in the overhead tank goes low and switches it off as soon as the water level reaches a pre determined level.
Since the input impedance of the comparator is very high very little current flows through the 1 mω. Before starting to design the circuit gather the following components. Possible applications for this water switch circuit. Than download the pcb file and open and print it and make your pcb.
