 hi!

i want to make a mini project on temperature contrller using 8051 or 89s51.can you please suggest me some good stuff?

reffer to the following links

temperature sensor…

The basic difference is channel number for analog input. 0802 is 2 channel, 0804 4 channel….like wise

hey thanks for ur reply now i have decided to make temperature controlled fan.can you please suggest me some links and want its circuit diagram 

hey friend nice project,

just use adc and microcontroller and calliberate it for different readings of temperature sensor and you can control the fan using a relay connected through microcontroller.

hey thanks nilesh.your suggestion will prove helpfull to me. 

ok pallavi i will help u .so u tell me what is the problem
