Nowadays, the efficient management of water resources is of paramount importance, especially in contexts where water scarcity and the need for constant monitoring are challenging. One of the biggest problems faced by resource managers is the difficulty of monitoring water levels in reservoirs in real time. This article presents an innovative design of a device based on the ESP8266, capable of monitoring the level of a water tank and sending automatic alerts to a Telegram group made up of maintenance professionals.
The objective of this project is to provide an affordable and efficient solution for monitoring water levels, to ensure a continuous supply and allow the team to quickly call a water truck to fill the reservoir. Choosing the ESP8266 is due to its internet connectivity capabilities and its compatibility with different platforms, allowing direct integration with instant messaging applications such as Telegram.
This device offers a series of benefits, from monitoring automation to real-time communication with a maintenance group, facilitating quick decision-making. Applicable in various sectors, such as industries, farms and homes, this solution was designed to meet the specific needs of maintenance professionals, ensuring greater efficiency and safety in reservoir management.
In this article, we will explore the development of the device prototype, its 3D printed housing structure, the tests carried out, the results obtained and the conclusions about its effectiveness. If you want to discover how this project can transform water resources management and provide a practical and innovative solution to a common problem, continue reading our article and discover all the solutions for you to apply in your projects.
Below we have the 3D printed housing structure to house the project’s printed circuit board.
Next, we will begin the construction process of the 3D model and presentation of the project's electronic system.
Electronic System DevelopmentThe device system is made up of two important parts:
- Electronic board for monitoring and connecting to sensors
- Electronic housing to house the printed circuit board.
See each of them shown in the image below.
The heart of this electronic board is the ESP8266 CHIP. He will be responsible for connecting to the internet, analyzing the reservoir level and sending alert messages to a maintenance team via Telegram.
Next, we will cover the complete system functionality of the ESP8266 and the code developed to control the system.
Control System with ESP8266The ESP8266 is a very versatile CHIP, with an affordable price and widely used in electronic projects that involve data exchange over the internet. Its ability to connect to WiFi networks offers you great capacity to create countless applications for monitoring processes and controlling devices over the internet.
In this application, the ESP8266 is intended to monitor the level of a water reservoir and transmit the level status based on the reading status data from each sensor.
The project requirements are presented below:- Send alert messages to Telegram every 2 minutes when the water level is at or below the minimum level.
- Send a message about the current level of the reservoir to the Telegram group, every 1 hour, when the water level is at or above the average level.
To perform level monitoring, the system has 3 inputs for float level sensors. From the reading of these sensors, the system will process the information and make a decision based on the state of each sensor. Below we have the structure of the float level sensor used in this project.
Next, we will present the operation of the electronic board control system.
Control System for Level MonitoringThe control system for level monitoring was developed with the ability to connect to any WiFi network, dynamically. This result was obtained through a feature that allows you to scan WiFi networks close to the device and present them so that the user can make a connection.
Device registration system on WiFi networkBelow we have the result of the page that was developed to allow the device to connect to any WiFi network.
The ESP8266 has been configured to create a network that allows us to connect to it. When energizing the device, a WiFi network will be created with the name “WiFi Tank”. Access the WiFi network with the password “wifitanque99” and this page can be accessed via IP 192.168.1.4
The code that presents the result of this page is shown below.

}Below is a presentation of the messages in the maintenance team group. As you can see, each alert is sent based on the conditions presented previously.
This way, the team has knowledge of the current state of the reservoir level and is able to make the best decisions in managing the site's water resources and ensuring that there is never a lack of water to supply the system. See the image of the alert messages.
To protect the printed circuit board from environmental impurities, we developed an electronic housing.
Electronic enclosure designThe electronic housing has the purpose of storing the printed circuit board, protecting the electronic board and facilitating the connection of power and other devices to the electronic board circuit.
From these points, we developed the electronic housing below.
The electronic housing is designed to provide access to the wires for the 3 level sensors and an input for the 9V power supply connector.
To facilitate its installation, we inserted two side structures for fixing to the wall using screws. See the figure below.
In the figure above you can see the two side flaps. In addition to this structure, we use insertion nuts in the internal region to facilitate fixing the electronic board and closing the cover with the help of screws. Its structure is presented below.
These elements are very useful when we want to create holes with metal threads. They facilitate the fixing of parts with screws and are highly resistant to wear, when compared to the plastic structure. Many designers use holes in the plastic structure itself to apply screws.
Now, see the structure of the electronic housing that was manufactured using FDM 3D printing technology.
Is it advantageous to use 3D printing in the manufacture of electronic housing prototypes? There are 4 important points that we can highlight the advantage of using 3D printing for your projects.
1 - Flexibility in design3D printing allows designers to create complex shapes and structures that would be difficult or impossible to produce with traditional methods. This offers a great deal of creative freedom, allowing the creation of custom housings that precisely meet the needs of the electronic device. Design changes and iterations can be made quickly, facilitating innovation and experimentation.
2 - Speed in developing prototypesWith 3D printing, you can go from digital design to physical prototype in a matter of hours or days, rather than weeks or months. This significantly speeds up the product development cycle, allowing you to quickly test and validate different designs. Problems can be identified and corrected earlier in the development process, resulting in a more refined and efficient final product.
3 - Customization and specific adaptationsThe ability to customize each housing according to the specific needs of the device is one of the biggest advantages of 3D printing. This is especially useful for electronic devices that require specific adjustments, such as precise fittings for components, openings for connectors, and other custom features. 3D printing makes it possible to produce small series of customized housings without significant additional costs.
4 - Cost savings compared to traditional manufacturing methodsTraditional manufacturing methods such as plastic injection can be expensive and time-consuming, especially for small production runs. Expensive tools and molds are required, making low-volume production impractical. 3D printing eliminates the need for specific molds and tools, significantly reducing initial and production costs. This makes 3D printing a cost-effective option for startups and small businesses that need to produce high-quality electronic housings in limited volumes.
All of these points are possible to be achieved when we use industrial 3D printing resources, as the machines have a higher level of precision and the company uses surface finishing techniques to improve the quality of the parts.
