0 The AC voltage from the stepdown transformer (12V, 15V or 18V can be used) is fed to the bridge rectifier (DB1) in order to get a DC volt. The heart of the circuit is the dual timer IC U2. 
Turns on the pump when the level of water goes below bottom level. Once the relay is activated, it will wait for few seconds and checks whether the water is flowing into the tank or not. 426 0 obj This circuit is used to drive a regular a/c cfl bulb upto 32 watts. endobj Transistor Q1 is used to detect the water flow. The negative of the output volt is connected to the L1 and C3 to avoid line disturbances. 453 0 obj Manual/Auto switch option is available in this circuit. Battery Level Indicator Circuit Using Dual Op Amp Ic LM358 To Monitor 12V Battery's full, normal and low level. The output pin 5 of U2 is fed to the base of the NPN transistor Q1 through a resistor R13. <>
When power fails and resumes later if the water level is below the bottom, it will automatically turn on the pump. Low cost circuit made out of readily available components. hb```g``:AX,+Om^8zQ>
rA:dX, X}X1o82!/604Mg;j!6@]&W+WH002e` 1 water level controller circuit uses a float switch to control the water level of the storage tank. It is achieved by directly connecting to the relay bypassing the circuit.
475 0 obj It is fed to the input of the regulator U1. Fully Automatic Water Level Controller Circuit With Motor Dry Run Protection Without Using Microcontroller, Here is the download link: https://kjmindia.myinstamojo.com/product/3261961/pcb-layout-for-automatic-water-level-control, C2, C3, C4, C7, C8, C13 - 0.1uF disc (104), Float Switch to be used : Vertical or Horizontal. If it reaches full capacity, the float switch will automatically turn off. Please ensure that you are using a good quality float switches. With a slight modification in the external connection, this circuit can be used as a semi - automatic water level controller too! This. The trigger and threshold pins 8 and 12 detects the low and high levels of water in the tank. endobj If there is no flow of water, it will automatically turn off the pump. Author : Manikandan K J This is a simple 20 led chaser circuit built using the decade counter ic CD4017 and Dual flip flop ic CD4013. Once activated, pump will be turned of by pressing OFF switch which is normally open type or when the water level touches the top float or water flow stops in the middle. We can also connect a Manual/Auto switch externally bypassing the relay. endobj This protects against overfilling and spilling of water. 423 0 obj As the components are readily available in the market, we can easily build this circuit. Once the unit is powered on, LEDs L2 and L6 will be turned On and the relay gets activated. %PDF-1.6
