desired. If the temperature is higher than desired the alarm will ring. The Data
Logger is a system which can save several measurements.
The basic principle of this monitor unit is to set up the desired room
temperature by entering via keyboard which compared to the actual room
temperature from temperature sensor LM 335. The system got the output signal from
LM 335 by the computer, an amplifier LM 308 and ADC HT 574 Z . The HT 574 Z
Analog to Digital Converter is a part from PCL 812 Card.
After determining the room temperature and the input temperature, the
computer will monitor the temperature if higher than the input temperature the
buzzer/alarm will ring and LED will light up to show wicb room exceed the
maximum input temperature.
By the testing here is a fault at the software and ADC HT 574 Z so that the
unit can't function.
