Hi,
I am computer science student and i want to attach a temperature sensor with computer such as LM35 via parallel or serial port. I have already made a circuit of relays for controlling the light bulb through pc using the parallel port and now i want to attach temperature sensor with that circuit so that whenever there is temperature rise a signal is send to pc about temperature rise but i donot have any idea how to do this and which components to use?? One way is to use microcontroller but that is complicated one and i donot have that much idea about electronics. Is it possible to do it just by using relays?? The circuit which i have followed for controlling the light bulb is as below:
**broken link removed**...
i donot want to build the circuit of sensors itself i just want to attach any sensor with the circuit.
If any can help me i shall be thankful.
Regards,
Heavenearth
