Water Level Control Kit

Club Jameco Electronic Kit Review

By Jackson Arcade
Kit Designer: rlarios

This water level kit from Club Jameco took between 1-2 hours for me to build. It's a really handy kit for learning the application of NOR gates and after I built it, it worked!

Build the water level kit

The NOR gate is a digital logic gate that implements logic NOR. A HIGH output (1) results if both the inputs to the gate are LOW (0), otherwise there is LOW (0) output. Build the project and you will get an idea of it.

I installed and soldered all the parts according the instructions shown in Figure 1.

If you are buying the AC to AC wall adaptor from Jameco, strip the ends of the female plug of the adapter so that you can connect the two leads to terminal block X1-1 and X1-2.

Now, have four 2 feet 24 AWG wires ready which will be connected to the terminal blocks X2 and X3. The two wires coming out of X2 are connected with the high and low level terminals on my Club Jameco tank (red and black wires respectively). The two wires coming out of X3 shall be dipped into the tank.

Next, you need to connect the water pump. If in case you don't have a pump, you can buy it from any hardware store. Cut the pump's live/hot wire as shown in schematic and connect the resulting ends to X4-1 and X4-2 terminals.

Caution: You shall be dealing with 120VAC power supply so make proper connections before applying power. Line voltage is dangerous and if mishandled can lead to injury or death

The pump is submergible and it stays in another tank filled with water as shown in Figure 2.

Connect a hose to the pump and leave the other end of the hose in the Club Jameco tank shown above

After making all the connections as shown in Figure 3, make sure to verify it against the schematic.

If all is fine, then you can proceed with powering up the kit and the pump.

As you power up the circuit you will see water being filled up in the Club Jameco tank and green LED should be ON. Nothing happens after water crosses the low level mark, but once the water touches the high level mark, the green LED should go out and you should hear a click from the relay. The water stops filling in!

Try to check out what happens when you empty the Club Jameco tank. As the water levels fall below the low level mark, you shall hear a click and the pump STARTS! This will start filling the tank until it has reached the high level.

You shall be able to achieve control between the high and the low levels.
