Dear all
can any one help me in making a simplest Temperature Reader(weather) and show on 7 seg displayby using ATmel 89c2051 and LM 35. Plz help me in sending asm or suggest.
regards
Interfacing the LM35 temperature sensor to 89C2051 will require additional A/D converter ..
Another option is to use temperature sensor with built-in A/D such as, for example, the DS1620 ..
You can find an example on this option at: https://www.iguanalabs.com/tempture.htm
