T-S1-800.900-I10-B01 4
designed for home use. This product revolutionizes the way temperature is measured by using
a temperature sensor “button”, called the ThermoSensor, which has been used in hospitals
since 2004.
By simply pasting the ThermoSensor (by sticking it to the inside of the diaper/undergarment),
temperature can be continuously and automatically measured and sent wirelessly to the
SmartNode receiver, enabling you to conveniently monitor your loved ones’ temperature,
without disturbing their rest and play, on your mobile devices or computers. The system allows
you to monitor the trend of the readings, enabling you to better manage fever. The readings
can be saved in spreadsheets for reference and further analysis.
1.4 International Awards and Recognition
The ThermoSensor has been given the following awards:
•Enterprise Challenge Innovator Award 2004, given to Cadi Scientific by The Enterprise
Challenge, a unit under the Singapore Prime Minister’s Office that funds innovative
proposals with the potential to create new value or significant improvements to the
delivery of public service.
•National Healthcare Group Scientific Congress Award 2006, given to Tan Tock Seng
Hospital for a clinical study on ThermoSensor presented at the congress.

1.7 How Does Cadi.Sense Work?
ThermoSensor measures your loved one’s temperatures periodically (every 30 secs)
and sends the temperature readings wirelessly to the SmartNode receiver.
SmartNode receives the temperature readings.
Cadi.Sense web-based application software enables you to view the
temperature readings in real time from a computer or smartphone via WiFi.
1.8 About Normal Body Temperature and Fever
The measured body temperature of a person depends on where it is measured, how it is
measured, when it is measured and how old the person is. In addition, the range of normal
body temperature varies from person to person. For temperature measured using
Cadi.Sense, a temperature higher than 37.8 °C should be considered a fever.
Please follow the step-by-step instructions closely to ensure that the ThermoSensor is properly
pasted.
Important Notes:
•Please note that the ThermoSensor may take about 10 minutes to heat up from room
temperature to the body temperature. A temperature reading is wirelessly sent every
30 seconds to your SmartNode, and this temperature reading will appear on the
Cadi.Sense application.
•Paste the ThermoSensor by sticking the adhesive part to the inside of the
diaper/undergarment, so that the sensor's metal part will touch the lower abdomen
(left or right) when the diaper/undergarment is properly worn. Note that temperature
readings may not be accurate if ThermoSensor is incorrectly pasted.

WiFi router’s manual). You may have to reboot SmartNode (taking about 2 minutes) by
switching it off and on again.
Step 4:
If UPNP feature is not available or not working, then you have to carry out manual port
forwarding. Basically, the objective of manual port forwarding is to instruct your WiFi
router to allow external (outside home) access of your SmartNode. Different routers may
have different ways and names for carrying out port forwarding (also called virtual
server), but the main information to be keyed into your WiFi router are similar:
(1) Device IP Address (also called Local IP): the LAN URL (please refer to Section 2.2
Step2), which is the LAN IP address of SmartNode
(2) Public Port (also called external port): 50000
(3) Private Port (also called internal port, local port, or host port): 80
(4) Protocol: TCP
(5) Enable: Yes
Note: (a) Please refer to the section “More Information on Port Forwarding” for details on
several different WiFi routers. (b) You may have to reboot your WiFi router for the settings
to take effect (please check with your WiFi router’s manual). You may have to reboot
SmartNode (taking about 2 minutes) by switching it off and on again.

5. Others
5.1 Frequency Asked Questions (FAQ)
About ThermoSensor
1. Why do we place the ThermoSensor on the left or right side of the lower abdomen and not
elsewhere?
It is well known that the temperature of blood in a major artery closely reflects body
temperature, so measuring temperature from an area close to a major artery will give
readings that are more accurate than those measured from an area far from a major
artery. We recommend measuring temperature from the middle of the left or right lower
abdomen because that area is near a major artery called the external iliac artery.
2. How do I know whether ThermoSensor is working?
Take out ThermoSensor from its casing and the LED light will start to blink about every 5
seconds. If it is not blinking, it is likely to have run out of battery or faulty. In that case,
contact Technical Support to purchase a replacement.
3. The ThermoSensor is correctly contacted but the temperature seems to be lower than
expected. Why?
•Whenever a ThermoSensor is contacted to the skin, it will take about 10 minutes to
give an accurate temperature reading.
•If the ThermoSensor is not held closely against the skin, the temperature reading will
generally be lower than normal. Do ensure that the sensor is properly contacted with
the application area.
•If the ThermoSensor is placed in the incorrect application area, the temperature
reading will generally be lower than normal.
•The ThermoSensor may give lower readings for obese people because the thicker
layer of tissue between the iliac artery (see FAQ # 1) and the skin surface may affect
the transmission of heat from the artery to the skin surface. If you suspect this is
happening, we recommend that you check your child’s temperature with an ear
