WATER LEVEL SENSOR V2.1

Today's project is an improved project and it works perfectly at 100% and many improvements in the PULL UP of the BJT transistors and to the output a current control up to 40A of any motor. We have included an AC/DC source

Here we will see the schematic diagram made in the easyeda software with all the electronic components and their respective values.

Here we will explain everything regarding our PCB, firstly we will feed our PCB with a voltage of 220VAC 60HZ since it has an integrated switching power supply TDPOWER 12VDC up to 1A that will allow me to control all electronic devices.

Then we perform the simulation with the pins from 0% to 100% with jumpers as a test or also with floating level sensors. The operation is easy when the tank level is below 26%, it will activate my motor so that I can pump and fill. The water tank, in turn, we can add a solenoid valve to open and close the pumping circuit in parallel to the second pumping motor, when it reaches 100% of the tank level, it deactivates the motor because it tells me that it is full and so it does not overflow. not very easy but we have indicator leds from 0% to 100%

This will allow me to see how level the water tank is.

when the output is activated at 220VAC 60HZ we can control a motor that supports up to 40A this will allow me to do it directly to the PCB since it can support its tracks up to 10A but if we need more than 10A we can reinforce the track with tin and have more current at the output.

This entire project is developed based on BJT transistors and resistors and for the SCR interlock, well, we will see below some devices and their operation in order to understand more deeply how they are behaving in this project.

Here we leave the easyeda BOOM file so that you can see what components were used to carry out this project, the pads of the SMD components

• VIN 220VAC 60HZ/50HZ
• VOUTPUT CONTROL RELAY 220VAC 40A
• V INTERNAL PCB 12VDC
• V INTERNAL PCB 5VDC
• IMAX 200mA
• TANK VISUALIZATION WITH LEDS AND FILLING CONTROL BY FLOATING SENSORS
• TESTED AND 100% FUNCTIONAL EFFICIENT

Once the project is finished with all the respective tests, we carry out the PCB design and we will obtain the routed tracks and the 3D image of how our finished PCB would look.
