GUI window for STTS424E02 temperature sensor
The STTS424E02 is a simple digital temperature sensor with an on-chip 2 Kb EEPROM.
Below are the steps to operate the STTS424E02 sensor in GUI mode:
1.
Plug the daughter card of the STTS424E02 on the motherboard.
2.
3.
Select the STTS424E02 sensor Radio button from sensor options in the “Select the
Temperature Sensor” area in the GUI. On selecting the STTS424E02 sensor, the “Edit
EEPROM” option also gets enabled in the GUI.

4.
Check the address from the “Choose Address” area. If the address configured on the
board (explained in
board (explained in
) is different from the address selected from the GUI,
an error message appears on the GUI. In the case of an error, re-check the address
with the correct option.
with the correct option.
5.
All the registers show the default readings at first selection.
6.
Press the Loop button to continuously read the temperature in the GUI.
7.
Configure the different registers through the GUI and observe the behavior of the
sensor. The bits of the configuration register can be individually selected using the GUI.

8.
Sliders for “Upper Temp Register”, “Lower Temp Register” and “Critical Temp Register”
can be used to separately configure the upper boundary, lower boundary and critical
limit for temperatures. Press the Write button individually for all the three limits to write
the value inside the sensor registers.
