1. Product Overviews
JAVS18-2011SG2 IOT real-time temperature monitoring wristband tag
is a real-time temperature monitoring wristband developed for the
epidemic of infectious viruses. Features of the product: high measurement
accuracy (0.1 ℃), multiple functions, strong real-time, big data collection.
Use to control the infection of virus; analyze the development trend of
virus; track the contact personnel.
The design and application of this product is mainly for schools,
factories, mines, enterprises, troops, government agencies, hospitals, etc.
In addition to the function of temperature measurement, this product also
has the functions of access control, attendance, positioning, etc.
The biggest advantage of JAVS18-2011SG2 is that it can detect the
body temperature of the personnel in real time, collect the measured data
to the cloud platform, and analyze the data through the cloud platform, so
as to predict the development trend of the epidemic and avoid the
recurrence of the disaster. Once the system finds out the abnormal
temperature, it will report to the competent personnel, and at the same
time, it will report the contact list.
Users' temperature measurement data, relatives or authorized personnel
can view the data through mobile phones or computers.

3.2 Wearing method
The temperature sensor face must be
worn on the inside of the wrist
Touch here once with your fingers.
Temperature and other information
can be displayed
Figure 3-1：Figure of correct wrist wear
When wearing the bracelet, the face of the temperature sensor
must be worn on the inner side of the wrist, and the tight point shall be
worn to ensure good contact between the temperature sensor and the
skin. Avoid incorrect measurement data.
In order to save power, the bracelet is usually in the screen saver state. If
you need to view data, touch the key with your finger. Enter display
measurement data. After 10 seconds, the bracelet enters the screen
saver state again.

3.3 Charging method
Step 1: remove the temperature measurement body from the bracelet.
The removal direction is shown in the figure below.
Figure 3-3：Take down the main method diagram of temperature measurement
Step 2: insert the charging line into the temperature measurement body,
and insert the other end of the charging line into the charging adapter
of the mobile phone (the product does not come with its own power
adapter).

Step 3: when charging, the battery will show green status. White when
full, the battery will show white status.
Figure 3-4：When charging, the
battery is green
Figure 3-5：When charging is complete,
the battery is displayed in white.
Step 4: after charging, install the temperature measurement body back
into the bracelet.

3.4 Manual clock calibration method
Step 1: within 1 second, touch the touch key 3 times or more to enter the
manual calibration.
Step 2: press the key once every 2 seconds, the current number (red
indicates the current operation bit) plus 1; if you press twice or more
times in 1 second, the current operation bit moves forward one bit. If
there is no key operation within 20 seconds, the device abandons the
current operation and enters the normal state.

In one second, touch the
touch key 3 times or more
by hand.

When the key is pressed once,
the operation result: from 2 to

When pressing the key twice, the
operation result: the operation
position moves down one bit

When setting the week, press
the key twice to finish the
setting. Return to normal.
3.5 Notes
➢Not suitable for bathing and swimming;
➢Use the self-contained charging line to charge;
➢Do not expose the bracelet to moisture, high temperature or
extremely low environment for a long time;

4. Bracelet connected to the Internet of things
图3-11：手环接入物联网图
After the temperature data collected by the bracelet is connected
to the Internet of things, a large number of valuable data have been
formed. Through the analysis of big data, it can predict the
development direction of the disease and avoid the occurrence of
disasters.
After connecting to the Internet of things, the bracelet can automatically
calibrate the time and temperature.
