The circuit is completely automatic which starts the pump motor when the water level in the over head tank goes below a preset level and switches off the pump when. Water level indicator circuit using uln2003 ic.
Water Level Sensor
Water level control circuit diagram. Also read the interesting concept about how water level alarm circuit works using 555 timer. This arrangement is encased in a pvc pipe and fixed vertically on the inside wall of the water tank. When you want to use just to turn on the tap at the bottom. Some homes have a large water tank on high then pumping up the put on hold. When there is enough water in the underground tank probes c and s are connected through water. The circuit uses 6 transistors 1 ne555 timer ic a relay and few passive components.
It does not require all time electricity and also high water pressure. Continuously check the water level input pins p00 p01 and p02. Here is a simple level switch circuit that switches on one relay and switches off another relay when the fluid level exceeds the set limitthis circuit is a modification of the simple water level indicator previously postedwhen the water level touches the probes positive supply is connected to the base of q1 through fluidthis makes transistor. The low level and high level probes in the overhead tank are marked l and h respectively. Though there are many solutions to it like ball valves which automatically stop the water flow once the tank gets full. As a result transistor t1 gets forward biased and starts conducting.
Automatic water pump controller circuit diagram. The water level is sensed by two floats to operate the switches for controlling the pump motor. Automatic water level controller circuit. Algorithm for water level controller circuit first configure the controller pins p00 p01 and p02 as inputs and p07 as output. Now initialize the lcd. Convenient and savings but.
The water level controller circuit is a simple mechanism to detect and control the level of water in the overhead tank and also in the other containers. Before starting the design process of this circuit lets give you a brief explanation of the uln 2003 ic. A simple but very reliable and effective water level controller circuit diagram is shown here. Each sensors float is suspended from above using an aluminium rod. Water level controller circuit water level controller circuit. We can design the water level indicator circuit using uln2003 ic as the main component.
Such sensors are more reliable than. Water tank overflow is a common problem which leads to the wastage of water.
