IOT Liquid Level Monitoring System Project

Project Cost: 8,400

Project Code: 5138

Description of the project

Level Sensors have a vast application in Consumer, Commercial and industrial processes. IOT based Liquid level Monitoring project is designed in a way that it can be used to remotely monitor the level of liquid indoors and out, like measuring tanks, wells, ponds, canals, and streams. In Industrial applications, IOT based Liquid level Monitoring projects can be used for leak detection, theft detection, and also monitoring the usage of chemicals. The IOT Liquid Level Monitoring System project enables the user to level detection of any liquid and continuously monitor it – over the internet.

Different types of level sensors like Ultrasonic, Capacitance, Conductive, Float sensors, etc. can be used for liquid level monitoring. We have used two Float sensors placed over the containers to determine the level of liquid, Arduino – that will read the level from these two sensors, and send it using IOT, over a webpage. This project is operated from a 12-volt transformer. However, a 12V battery can be used to power the circuit. The level of the liquid is displayed in percentage on an LCD display.
For E.g. If the container is of capacity 100 Litre and is completely filled, the System will display 100%
If the container has 50 Litre liquid, then the system will display 50%.

A detailed description of the project:

As the liquid level in one container lowers, the float sensor which lies on the surface of the water also goes down along with the liquid level which in turn causes the resistance to go down. The difference is read and sent to the Arduino. At the same time, an LCD display would display the level in percentage. This reading is also sent to the website using IOT, in which real-time liquid level monitoring can be done from any remote area.

For demonstration purposes, we have used two containers having one float sensor each. A buzzer is also used, which will turn ON when the level of liquid reaches a certain minimum value. This minimum value can be set, as per the requirement.

This project is also implemented without the IOT module and with the GSM module. However, the limitation of SMS based project is that it can send SMS to 5/10 people. Since the time to send SMS increases with the number of SMS.

Technical Specifications

The components that are used in the Liquid level monitoring using Arduino and IOT project are

1. Float sensors which would lie on the surface of the liquid
2. Microcontroller – Arduino Uno. Other microcontrollers like 89c51, 89s52, 89v51RD2, PIC18F4550, and AVR ATmega32 can also be used

3. ESP8266 – The wifi module is used to connect the Arduino to the internet for sending data to IOT provider websites.
4. An LCD display that would display the level of the liquid in percentage
5. A 12V power supply

Questions and answers about this project:

Question: Can this project be used to monitor any solid or powdered material stored in a container?

Answer: This project cannot be used to monitor the solid material. But, for powdered materials, this can be used.

Question: How many users can monitor the liquid level, remotely?

Answer: We can create User names and passwords and give access to as many people as we want.

Question: Can this project be used to determine Fuel level? Will it be safe?

Answer: Yes. Fuel level detection is also one of the applications of this project. Since we are using float sensors, it is absolutely safe.

Applications, Advantages, and Future Development of IOT liquid level monitoring system

1. Continuous monitoring of any liquid – Water stored in a container OR a lake or pond, Chemical – stored in big containers in Industries.
2. These monitoring can be either to calculate the usage OR to keep a check on leakage as well as theft detection.
3. Since the project uses IOT; the liquid level monitoring can be done from any remote place.
4. The user has a history of records since these records are stored on a website database.
5. This project can be tweaked to get the liquid level details in a message on any mobile phone. E.g. If a certain chemical used in a factory goes beyond 50%, a message is triggered and sent to any registered number, OR a notification is sent over an app.
6. This project can also be developed on Bluetooth technology.
