You can remove the plastic enclosure with electronics at any time and let your child play with plush Teddy with no fear.

How does Teddy the Guardian track your children's vital signs?

Sensor captures infrared rays from the skin and sends the gathered information to the processor. Processor then filters and calculates all the data and sends it via Bluetooth to the phone for final processing, so you can see the result.
You will notice that the outer circle on the screen is loading while sensor captures the data and calculations and processing are in progress. Reading will appear on the screen as soon as the measuring is done.
You can easily find the list of all measurements in Reports section. All your data is shown in tabular and graphical form.

How do I know that the measurements are accurate?

Teddy the Guardian is not a medical device and therefore can not be a substitute for certificated medical devices. When you get the result that is higher or lower than normal, we advise you to double check the measurements with conventional medical device.

You can measure temperature in three ways:

2. By putting the sensor on forehead.
3. By hugging the toy and placing the sensor under arm.You can measure heart rate and oxygen saturation by laying a finger on the sensor, we also advise you to use a thumb to get better results. Make sure that the finger covers the whole sensor with infrared light.
