. The buzzer will also indicate when the water level is high. We also use third-party cookies that help us analyze and understand how you use this website. Commercially, to indicate the water level of overhead ranks. We can also make this project at a minimal cost. The JSN SR04 M-2 module can measure 20-400cm. Next, cut a 3 * 5-inch piece and attach the LED to it. If you are using the waterproof JSN SR04 M-2 ultrasonic module, connect the pins as shown in the diagram. At PCBWay, all the boards pass through the most stringent tests other than the basic visual check. The ULN2803 is an eight-Darlington-array ICwith eight Darlington transistors.

You can also use a hand drill for drilling. So, the required components are given below. You need to measure the tank depth. Build your own non-contact. I hope you have liked this electronics project, Thank you for your time. I hope you, more Analog output with Arduino UNO board. We talked about how digital pins work in a previous article. medianet_width = "320";
Afterward, connect these LEDs and an Ultrasonic sensor to the Arduino board. Refer to the diagram below to connect the SR04 ultrasonic sensor with the MCU board. By integrating the smart water levels sensor with Home Assistant, you can add automation to get alerts on your smartphone or via Alexa/Google Assistant when the tank level is low or full. After placing spacers between the mounted washers, they're put in a glass tube to keep out wind, rain, and bugs. Although its not as intuitive as Home Assistant, it does the job and reports the raw value via a web page. {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/3\/34\/Make-a-Water-Level-Indicator-Step-1.jpg\/v4-460px-Make-a-Water-Level-Indicator-Step-1.jpg","bigUrl":"\/images\/thumb\/3\/34\/Make-a-Water-Level-Indicator-Step-1.jpg\/aid6691960-v4-728px-Make-a-Water-Level-Indicator-Step-1.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"
