Neebo has 5 different sensors which collect and analyze data. The main technologies Neebo uses include:
The Photoplethysmography method which monitors your child’s Heart Rate (HR) and Oxygen Saturation Levels (SpO2). An optically obtained plethysmogram is used to detect blood volume changes in the microvascular bed of tissue.
- Photoplethysmography is obtained by using pulse oximeter sensors, you often see in hospitals, which illuminate the skin and measure changes in light absorption. The data received is compared against the Reference ranges, if the value is outside it, you will receive an alert. You can read more on how the Reference range is determined here or how Alerts work here.
- Your child’s thermal comfort is monitored by analyzing surface temperature oscillation on the extremities, using data collected by a contact temperature sensor. The data is also compared against the Reference range. Please note, Neebo doesn’t measure core body temperature, here you can find an explanation of why and here you can read about how the Reference range is determined for the Thermal state feature.
- The audio environment is recorded by a microphone combined with data from the accelerometer and analyzed by machine-based software to identify events (e.g. your child waking), which is then further verified by data from motion sensors.
