If we talk a little bit about this project it can be used primarily for our home water tank. Monitor the level in your water tank with an ultrasonic sensor in the lid, and add optional automation. Thus, We may use this basic system in a variety of places. Enjoy this project. There are 8 pins on each side and a notch at one end of the IC. The steps are as follows: After downloading the firmware, click Open ESPHome Web. Even though the buzzer isn't attached directly onto pin #12, it still works because the wires are connected in a circuit. Click. For more help, including how to test your water level indicator, read on! You can follow the steps below to build a smart Wi-Fi-based contactless ultrasonic water level sensor to monitor water consumption and save yourself from climbing the stairs or water tank to check it manually. List of Hand Tools for DIY Projects For the Beginners. When the points are soldered, connect pin #12s positive point to pin #9. You can also download the PCB Gerber file. Thanks to all authors for creating a page that has been read 28,274 times. In this DIY guide, we will build such a water level indicator using a NodeMCU board and an ultrasonic sensor that sits at the top of the water tank cover and reports the data to your smartphone via Home Assistant. In this electronics project, I have explained how to make a simple Water Level Indicator using the BC547 transistor.

Last Updated: February 21, 2022 Learn more Making your own water level indicator is a fun school science project or if you just want a simple indicator for your home water tank. With the notch toward the top, pin #1 is next to the notch on the left side and pin #8 is at the bottom left side. You can also use this sensor to monitor a salt tank level. If you dont want to install or set up Home Assistant, you can flash the Tasmota firmware and use it to check the water level. Once the ultrasonic sensor is connected to the MCU, reconnect the USB cable. You will also need wire cutters to cut the sensing wires to size. To continually monitor the level of water in the dams. The shorter sensing wires measure higher water levels, while 1 of the longest wires measures the lowest water level. An ESP8266-based MCU, such as NodeMCU, D1 Mini, ESP01, etc. Also, we can monitor the water level using the LEDs in this project. To make it waterproof, we used a transparent case and sufficient nail polish to insulate the electrical components on the board. wikiHow's Content Management Team carefully monitors the work from our editorial staff to ensure that each article is backed by trusted research and meets our high quality standards.

If you see "Distance measurement timed out", do the following: To add the ultrasonic water level sensor to Home Assistant for monitoring, follow these steps: You may further customize the default card by adding the following in the code editor: You may now install the sensor in your water tank. We have, more How to use MQ2 gas sensor with Arduino | Step by step instructionsContinue, How to make a Bluetooth control 4WD car Hello guys, Welcome back to my SriTu Hobby blog. 
In industries, the level of chemicals that can flow is detected using level indicators. [Code and circuit diagram], Linear hall effect sensor module with Arduino | How it works. You can use this circuit in any water tank to sense the water level. The cookie is used to store the user consent for the cookies in the category "Performance". I have used their services for my different electronics projects, I always received the PCB on time and the quality is very good in this price range. The length doesn't matter, as you will be cutting them to size later on. I have used a 5V DC supply, but if you want to use a 12V DC supply, then use the 12V DC buzzer (no other changes required). OK, now lets set up the program for this.

The negative point on each LED is the short lead, while the positive point is the long lead. All rights reserved. Now, glue the LEDs connected cardboard piece to the top. But what if you could build a wireless and contactless Wi-Fi-based water level sensor that reports the remaining water in your tank directly on your smartphone? Here to make the PCB I have used an acrylic sheet, but you can also order the custom-designed PCB for this project from PCBWay. Looking for a way to monitor water levels without relying on expensive electronics or Internet connectivity, they went back to basics and built a fairly simple setup using a vertical array of magnetic flip-dot pixels. Here I have used only BC547 NPN transistor to sense the water level. Then, drill the holes as per the PCB layout for components. "It helps me a lot for my science exhibition, thanks for your help.".
