hi,
i like to tell something abt the same project, that is temperature
indicator using 89c51.ie,v r doing digital thermometer,it consist of a
sensor,LM35 which is acting as a current to voltage converter, n the
output of the sensor will b given to an ADC whose output is in digital
format.This digital format information is our temperature whcih is in
the form of voltage.Inorder 2 convert it to corresponding temp,v uses
a microcontroller,ie 89c51.And the output of the mc wil provide to the
LCD display.
And if it is needed v can provide additional facilities like
temp range indicator etc.acually i wan ur help inorder 2 modify the
same project with additional ideas ie using this same principle other
than temp measurement can v do somethin else with the same circuit.ie
extra fittings.thank u
Max and min temperature, logging to a file for the year, humidity with
a different sensor, air pressure with an other sensor, wind speed and
direction with yet an other sensor..., radioctivity with [], light
sensor for the shades, and count the sunny days, rain sensor, sound
pressure sensor, lightning detector, CO detector, other gasses detector,
passive IR detector, etc...
Enough?
.
