On these days water level indicator provides a great relieve with its simple mechanism. It is as simple as detect and indicate water level in water tank \/ water reservoir by activating applied features. Some can detect water load and enable\/disable pump eclectic supply, or some can blow alarm beyond water level.<\/p>\n\n\n\n

” Water level sensor working principle is when the sensor is sensing water or put into certain depth, the pressure on the sensor’s lower layer converted into water level height. The calculated formula is \u03a1=\u03c1.g.H+Po, ” <\/em> Where P is Pressure on the sensor’s lower layer, \u03c1<\/strong> is the density of water, Po<\/strong> is the atmospheric pressure of water surface area, g is acceleration to the gravity, H is the depth at which the sensor inside water level. <\/p>\n\n\n\n

There are different types of water level sensor which is used based on application to application. Other types of water level sensors can be found in https:\/\/google.com<\/a> or we will update in future if we have demonstrated any other water level sensor.<\/p>\n\n\n\n

Water level sensor has 3 pins (VCC 5v [+], GND [-], Source [Analog Input]). You can see below picture for connections. This code is implemented as when water sensor detects water level (Touch to liquid) it activates PORTD PIN0. This PIN0 is connected to relay module (5V). You can feel a delay in response while reading signal and enable\/disable relay due delay mechanism. It is required to give some delay of sensing the water to ensure constant water and delay time also helps relay to power ON pump or power OFF pump.<\/p>\n\n\n
