Hello

I'm trying to design a greenhouse by the use of one microprocessor and one computer outside the greenhouse. The microprocessor will interact with the rest of the system to mesure the humidity, de temperature, the pression of the valve( valve to pum water) inside the greenhouse and so on.

Please i want to know what type of microprocessor i can use for this
what type of communication between microprocessor and the outside PC?
what type of temperature and humidity sensor?
what type of pression sensor to mesure the valve?

what type of communication within the greenhouse ( between differents sensors).

Thanks for your understanding

NB: the distance between the greenhouse and the outside computer is almost 100 m or plus

 

depends on nof sensor, start with 16F877A or higher .
for short distance , use rs232 , longer use rs485
search on google
why is this needed ?? , and if needed , sensors cannot communicate unless each has something like a micro.
