3.2. Sensors
The temperature sensor (1) for reading the temperature on the surface of the glove is located on the ring ringer and
is protected by a cover made of DuPont™Nomex®material while also being in contact with the surrounding air. The
maximum measured temperature range of the sensor is -50 °C to +500 °C.
The IR sensor [infrared sensor] (2) for measuring temperatures of remote objects is located beneath a silicon cover
on the back of the glove. The maximum measured temperature range of the IR sensor is -70 °C to +380 °C. The
accuracy of the measured temperature of the remote point depends on the distance between the glove and the
measured point (Fig. 3 and 4). The measured surface increases as the distance grows, possibly distorting the results.
The laser pointer (3) located next to the IR sensor shows the user the measured area of the remote object. The
pointer is functional only when using the IR sensor [mode 2].
3.3. LED bar graph
The LED bar graph (5) is located on the back of the glove and is protected by a clear silicon cover. The bar graph
is made up of five LEDs in various colours: one green, two orange and two red (Tab. 2). The colour changes when
set temperature limits are exceeded and the user is visually informed of the current measured value. At any given
moment, the bar graph displays values measured from only one of the sensors – either the temperature sensor or
the IR sensor.
The temperature resistance of the silicon case: -50 °C to +230 °C, short-term up to +300 °C.
3.4. Switch (Power switch/Mode switch)
The glove is switched on by pressing the button on its back (4). The glove is switched off by pressing the same button
and holding it down for 4s. While running, the mode of the device can be switched by quickly pressing the button. In
basic mode 1, the device is set to read temperatures on the surface of the glove using the temperature sensor. The
level of the measured temperature is indicated by the LED colours on the bar graph. By pressing the button again,
the device is switched to mode 2 to measure the temperature of remote objects using the IR sensor. The level of the
measured temperature is again indicated by the LED colours on the bar graph. The laser pointer is activated when
the IR sensor is in use. Another short press of the button returns the device to mode 1.
3.5. Status LEDs
The status LEDs (6) inform the user of the charge status of the glove accumulator and the wireless connection with
the smartphone. If the glove accumulator is adequately charged, the blue light is on. A red light indicates that the
accumulator charge is less than 30%. A blinking red light indicates that the accumulator charge is critically low at
less than 10%. The moment the glove is paired with a smartphone, the blue light blinks 5 times.
Status Visual display
The accumulator is sufficiently charged (100-30%) Blue
The accumulator must be charged soon (30-10%) Red
The accumulator is almost dead (10% -0%) Blinking red
The glove is connecting to a smartphone Blue diode blinks 5 times
