Our water sensor is easy- to-use, portable and cost-effective, designed to identify and detect water level and water drop. This sensor measures the volume of water drop and water q uantity through an array of traces of exposed parallel wires. Compared with its competitors, this sensor is not only smaller and smarter but also ingeniously equipped with following features: i)smooth conversion between water quantity and analog quantity; ii)strong flexibility; this sensor outputs basic analog value; iii)low power consumption and high sensitivity; iv)directly connected to microprocessor or other logic circuits, suitable for a variety of development boards and controllers such as Arduino controller, single-chip microcomputer, etc. Specification Operating voltage: DC5V Operating current: ﹤20mA Sensor type: Analog Detection area: 40mm x16mm Production process: FR4 double-side tinned Humanized design: Anti-slippery semi-lunar recess Working Temperature: 10℃-30℃ Working Humidity: 10%-90% without condensation Connection Diagram Sample Code int analogPin = 0; //connect water sensor to analog interface 0 int led = 13; //LED to digital interface 13 int val = 0; //define the initial value of variable ‘val’ as 0 int data = 0; //define the initial value of variable ‘data’ as 0 void setup() { pinMode(led, OUTPUT); //define led as output pin Serial.begin(9600); //set baud rate at 9600 } void loop() { val = analogRead(analogPin); //read and assign analog value to variable ’val’ if(val>700){ //decide whether variable ‘val’ is over 700 digitalWrite(led,HIGH); //turn on LED when variable ‘val’ is over 700 } else{ digitalWrite(led,LOW); //turn off LED when variable ‘val’ is under 700 } data = val; //variable ’val’ assigns value to variable ‘data’ Serial.println(data); //print variable ‘data’ by Serial.print delay(100); } Phenomenon After the above steps are done, let’s do a test on lower water level and check what happens:The LED can’t light up when water level haven’t reach alarm value;The LED is turned on and an alarm is released when water level reaches alarm value.
