Agricultural warehouse cloud enabled infrastructure

the main objective of the project is to monitor the ambient atmospheric conditions for proper food grain storage. we have to implement a monitoring and controlling system that monitors weather parameters like temperature, humidity, light and gas. these parameters are sent to cloud. a web page is designed for remote monitoring of weather parameters in food storage room. an app is also designed for controlling the appliances in the room for maintains optimal weather parameters.

PLEASE PROVIDE THE CODES BOTH HARDWARE AND SOFTWARE its really urgent

How much are you looking to pay someone to design all of this for you?

You’ve given so little detail about what you want I suspect you’ll get no response. You’ve not even specified the food hygiene standards (amongst others) that have to be met.
