hi!
i have a query for difference bw two devices.I have a project in which I am using AT89C52 and ADC0804, but I have a query, what is the the basic difference among ADC0801/0802/0803/0804?
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.
