wrong chip in code (DS1820 Based Temperature Controller (AT89C2051))

hi rickey
in download section the project of "DS1820 Based Temperature Controller (AT89C2051)"
contain the circuit and code.
the circuit is using ds1820 sensor which is 3 pin ,i wire interface device.
but in the code . it is using ds1620 chip which 8 pin and three wire interface
please correct this

oh! i have to check this and... mail the author about it... :-s ....thank you ritesh :-|

first the new 8051 projects are very good and interesting second
there are also some problem in few projects
1)in "RFID Based Attendance System (AT89S52 + RFID)"the circuit diagram is wrong
2)in "PC BASED DATA LOGGER (AT89S52 + VB)" project.
there is no source code instead of vb files
3) in RFID based both project . there is incomplete information about RFID itself.

Ritesh, as i am trying.. to contact and not getting any response.. yet..
if you know whats the problem with the project then make it correct... will be nice..

i will try my best

thanks!

In Temperature controller, the IC number is wrong and the circuit is also wrong. The program is for DS1620 based Temp controller.
The circuit is posted here.

For RFID based attendance system please delete the ULN IC from the circuit.

PC based data logger progam is given below

binu can you zip the circut and upload it here?
