When sound waves are transmitted in environment then they return back to the origin as ECHO after striking on any obstacle. %PDF-1.5 A pulse is sent for about 10us to trigger the module. With this Water Level Sensor, you can do just that! To program Arduino forwater level controller, first we define all the pin that we are going to use in the project for interfacing external devices like relay, LCD, buzzer etc. This sensor module will read the distance between sensor module and water surface, and it will show the distanceon LCD screen with message Water Space in Tank is:. In this sketch two variables are defined viz. After it we check conditions if water tank is full or water level is LOW, and take actions accordingly. So we have to only calculate its traveling time of both sounds means outgoing time and returning time to origin after striking on any obstacle. morphettville xT;O0_14M/)B&cNmTR?>JPxK''WH:)zHBHYN{u]yb{[ ~ :iDy?KvdkhjV}l%:1r} M1?&qS/ij]tX``[$ /m;0wVAr:,n?yvTa}U(V We also use third-party cookies that help us analyze and understand how you use this website.
