How to sense the value and display it onto the LCD?

Projects General Guidance

Hello,

AIM OF MY GRADUATION PROJECT: To build an autonomous real time device to measure the physical and chemical parameters of water using Arduino(an open-source physical computing platform based on a simple microcontroller board, and a development environment for writing software for the board.) Atmega 2560 Microcontroller.

HARDWARE TOOLS FOR MY PROJECT:
Arduino Atmega 2560 development board
4x4 Matrix Keypad
16x2 LCD
Series 2 Zigbee Pair
Physical & Chemical Water Parameters Sensors(Ph Sensor, Conductivity, Dissolved Oxygen, Temperature and level sensor)

I'm being working on ARDUINO ATMEGA 2560. Can anyone help me with the programming part of sensing the sensor value and displaying it onto the LCD?

Thanks

Where's your program as it stands, the link detailing the sensor and the link detailing the LCD?

Sensors Im using are Ph, COND, DO, TEMP & Level

And the program I have attached

You need to first communicate with the sensors you have using any of the communication protocols they use like the i2c, one wire, spi ,uart , analog etc and then you need to process the extracted data into information then convert the value in string to be loaded into the print method of the LCD.

I dint get you .. could u explain with a sample code??

6

Have you worked through the examples provided with the IDE?

7

Yes I did... but not able to write a code for sensor .. how to write a code for Ph Sensor??

whats the comm. protocol for your ph sensor, essentially which is actually your ph sensor? theres no link to it or anyothe info. at all.
