Introduction: Arduino Based Wireless Water Level Indicator

Intro:

This device consists of a transmitter and a receiver. The transmitter device comes with a (5"long and 4" diameter) cylindrical cover(pvc). It has a sonar sensor downward. when the device is turned on, set it on a 2' long 4" diameter pipe. this pipe has a float-able material inside. so, when the water level rises, the sonar sensor feels the float-able material closer to it and sends the data to Arduino board. the value is very accurate . Further, using a RF transmitter the data is sent to the nearest RF-receiver .

The receiver device receives the data and shows the output in the computer screen.

Components :

  • Arduino-uno - 2 pcs
  • Sonar Sensor - 1 pcs
  • RF Module - 1 set
  • battery-9v_dc - 1 pcs
  • Led - red and green
  • UPVC pipe

Step 1: Sensor & Transmitter Setup

Following block diagram and pictures can help you to setup the sensor and transmitter circuit. addition of extra led can indicate the safe and danger marks.

Step 2: Receiver Circuit

Step 3: Tools

#All the libraries and final codes are uploaded.

#Remark:

·

  • The ultrasonic sensor can measure 3cm-400cm distance precisely. so the water level is measured very accurately
  • In our code we used some 500ms-1000ms tolerable delay.
  • The communication between two RF-modules take time. The measured delay is between 1000ms-3000ms.
  • ·As the battery voltage goes down, the communication process becomes slower.
  • · The measurement of pipe matters . it's found out that 4"diameter & 2' long ratio works the best

Hi,

This is a cool project, I just have few queries:
1. Won't the exposed part of sonar get corroded due to exposure to humidity, how do you avoid that
2. Please provide more detailed circuit diagrams so anyone can redo things

I am looking forward to build this.

Thank you
