Introduction

Our water sensor is easy- to-use, portable and cost-effective, it is designed to identify and detect water level and water drop. This sensor measures the volume of water drop and water quantity 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:

• smooth conversion between water quantity and analog quantity;
• strong flexibility, this sensor outputs basic analog value;
• low power consumption and high sensitivity;

directly connected to microprocessor or other logic circuits, suitable for a variety of development boards and controllers such as Aduino controller, STC single-chip microcomputer, AVR single-chip microcomputer and 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

Operating temperature: 10%~90% without condensation

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);

}
