Automatic control and display of Room temperature

hello every one and i hope they all ok could u help me


A temperature sensor is to be interfaced with a PC and an output signal is to control the flow of hot air into the room. A high level language is to be used to provide the control algorithm to maintain the temperature in the room by controlling a flow valve.
A real-time visual display of the temperature should also be provided.

could i use by this way , by use PIC 16F877 and i thing this chip because there is A/D (analog to digital)convertor.and the PIC 16F877 it will read the temperature from temp sensor LM35 , i thing this LM35 because it's more sensitive to tempreture and the output is constant 10mv/1c and it's linear , then it will convertor to digital then send to PC by serial port.

now the problem i do't know how to do the program in a high level language?

is this my way right. and how to do the program?

thank you very much

best regards

Have you heard of LabView?
Here is a link to "Using LabVIEW to Send Commands via RS232 ... ":

Maybe you can have a look at that option ..

I can give you the total solution using 89c2051 with any digital temperature sensor with (IIC or SPI) or your LM35 with a ADC. If you want the solution do mail me on rituparnasaikia@gmail.com
