Connection Details Of 6 Led Water Level Indicator



SENSOR
1 – F(L) – Used for water flow sensing
2 – +ve supply – Used for water flow sensing
3 – +ve supply – Kept inside the tank but should not touch the bottom of the tank.
4 – First Level
5 – Second Level
6 – Third Level
7 – Fourth Level
8 – Top Level
Both 1 and 2 are used for water flow sensing in the OHT or low water level sensing inside the sump.
LED- should be connected to the negative terminals of the 6 LEDs.
LED+ should be connected to the positive terminals of the 6 LEDs. All +ve terminals should be shorted together.
Preset should be adjusted for the wait time as per your requirement.
Buzzer should be connected with the correct polarity. Brown wire(+) and black wire (-)
Use 9v,500mA – 1A step-down transformer. We can also use 15v transformer. In this case, we have to use 7812 regulator ic in the U3 slot on the board.
We can use 8 colour flat ribbon wire/Cat-6 wire to connect the sensor in the tank to the indicator unit.
For sensor, we can use thick copper wire/aluminium/steel wires or magnetic float switches.
LED Details:
Green colour LED can be used as power indicator.
Red can be used to indicate top level
Tricolour LED can be used to indicate the water flow
White colour LED can be used to indicate other levels.
