Water storage typically presents challenges comparable to monitoring tank ranges, stopping overflow, and decreasing guide intervention to function the pump. Two varieties of gadgets, often known as water degree indicators and controllers, have been developed to deal with these points.
These gadgets have key drawbacks. Water degree indicators require guide pump operation and infrequently waste energy as a number of LEDs keep unnecessarily lit. Water degree controllers face frequent pump biking from minor fluctuations, accelerating the pump’s put on and tear and shortening its lifespan.
Additionally, Verify the Water Pump Controller challenge that we constructed beforehand.
An computerized water degree indicator cum controller machine can tackle these issues. To construct this machine, the elements listed in Desk 1 are required. Fig. 1 exhibits the creator’s prototype.

Arduino Code for Water Stage Indicator and Controller
The code is written in Arduino IDE. First, the IDE have to be put in. The code can then be downloaded and opened in Arduino IDE.
Within the preliminary a part of the code, sensor wires, LEDs, and the relay pin are outlined. Within the setup operate, the pin modes are configured as enter for the sensor wires and output for the LEDs and relay.
Within the loop operate, the degrees are detected utilizing the learn operate. Primarily based on the detected degree, the relay activates or off, controlling the motor related to it.
The board and port for the Arduino Uno needs to be chosen. The Arduino Uno ought to then be plugged in, and the supply code uploaded. Fig. 2 exhibits a snippet of the supply code.
Circuit
Fig. 3 exhibits the circuit diagram of the automated water degree indicator cum controller. It’s constructed round an Arduino Uno board (MOD1), three LEDs, a 5V SPDT relay, and different elements.
First, all sensors needs to be put in within the higher tank, and the pump motor needs to be put in within the decrease tank.
The circuit can use both wires as sensors or float switches.
Working
Filling Mode
Throughout water filling, the three wire sensors are positioned at totally different heights within the tank. The pump motor begins robotically when water is under the bottom sensor.
When water touches the bottom sensor, LED1 lights up, however the pump stays on. When water touches the center sensor, LED1 turns off, LED2 lights up, and the pump stays on.
When water touches the very best sensor, LED3 lights up, LEDs 1 and a couple of flip off, and the pump switches off.
| Desk 2: Filling mode | |||||
| Sensor Place | Situation | LED1 | LED2 | LED3 | PUMP |
| Water touches no sensors (under lowest sensor) | Tank is empty | OFF | OFF | OFF | ON |
| Water touches the bottom sensor | Tank just isn’t empty | ON | OFF | OFF | ON |
| Water touches the center sensor | Tank is partially crammed | OFF | ON | OFF | ON |
| Water touches the very best sensor | Tank is full | OFF | OFF | ON | OFF |
Draining Mode
Throughout water drainage, when the water degree drops under the very best sensor, LED3 turns off, and LED2 lights up, however the pump stays off.
When the water degree reaches under the center sensor, LED2 turns off, and LED1 lights up, however the pump stays off.
When the water is under the bottom sensor, all LEDs flip off, and the pump begins.
| Desk 3: Draining mode | |||||
| Sensor Place | Situation | LED1 | LED2 | LED3 | PUMP |
| Water degree is on the highest sensor | Tank is full | OFF | OFF | ON | OFF |
| Water degree is under the very best sensor | Tank is partially crammed | OFF | ON | OFF | OFF |
| Water degree is under the center sensor | Tank just isn’t empty | ON | OFF | OFF | OFF |
| Water degree is under the bottom sensor | Tank is empty | OFF | OFF | OFF | ON |
Testing
The supply code should first be uploaded into the Arduino Uno. The elements ought to then be related as per the circuit diagram proven in Fig. 3. The Arduino Uno board needs to be powered utilizing a 5V adaptor or a USB cable related to a laptop computer or desktop.
The water pump needs to be related to a 230V AC energy provide by the relay contacts. After powering the machine and putting in the sensors within the tank, water needs to be crammed into the tank. The LEDs will glow in line with the water degree, and the pump will change on or off as described in Tables 2 and three.
