The water degree indicator is a gadget that receives statistics about the water degree in tanks which is utilized in houses and public places. We can manage the overflow of water tanks by using the tank level indicator. As every person realize when the water is saved in the tank, no person can perceive the real stage of water inside the water tank. That is manner mainly water tank overflow and its high-quality lack of water as well as energy.
Water degree indicator
in this easy water degree indicator task, we’ve used a switching ic uln 2003 to signify the water inside the tank. These days many tasks on water indicators are to be had which include slope indicator water stage meter, digital water level indicator, water indicator the usage of transistors, water degree indicator alarm, etc.
Water degree indicator the usage of ic uln 2003
on this circuit, we are using switching ic uln 2003 usually used switching ic.
Components utilized in those projects areas:
uln2003 is a excessive contemporary and high voltage darling-ton array ic. It includes seven open collector darling-ton pairs with commonplace emitters. Darling-ton pair is an association of bipolar transistors. It’s far a relay driving force ic other kinds of similar ica are high side toggle switch, low side toggle transfer, darlington transistor, bipolar npn transistor, n-channel mosfet, uln2003 driver ic, and so forth. Led s this ic has 7 output pins which can be why we’re going to use 7 leds as water degree indicator inside the tank. This led s will glow in step with the extent of water in the tank. Battery: a dc supply of 9v is given via a battery to power up the circuit or you may use 9 to 12v dc supply as energy. Resistor 220-ohm resistors are used in this circuit to protect the leds due to the fact we’re using 9 volts to 12 volts strength deliver. Circuit diagram of final initiatives
water tank level indicator
on this following animated circuit diagram, we’ve got cleared all components with their connection you may use lengthy wires consistent with the gap of your tank to electric board. Water degree
indicator the usage of alarm
we can also use alarm with this circuit. It’ll warn you that now the tank is full and also you should flip off the water pump.
Tank level indicator auto powered off
we can also use a cut off relay with this circuit, whilst the tank might be complete relay will reduce off the electricity routinely.
Water tank degree indicator
in this circuit given about we’ve got cleared all connections with automobile reduce off water pump when tank might be complete water pump will vehicle flip off due to the fact a relay is connected with the seventh output of ic. Uln2003 pin description
