Origins
One key aspect of applying wearable devices for health monitoring is using PPG (Photoplethysmography) technology to measure heart rate. Wearable device manufacturers not only need to ensure the accuracy of the heart rate function but also meet the demands of mass production to stay competitive, making efficient production line testing essential.
In response to the testing need, we developed the HRS100+, which simulates PPG signals using green light. Engineers can quickly test whether the device performance meets manufacturer standards by adjusting parameters such as heart rate (BPM), brightness reflected by different skin tones (DC), and the perfusion index (PI = (AC/DC) x 100%) via HRS100+ software.
Engineers can also use the "Command Mode" to store frequently used test command scripts, creating standardized test files for repeated testing. Additionally, with the free software development kit (SDK) provided, they can develop customized automated testing software, eliminating the need for manual settings.
Functions
Adjustable BPM, DC, and PI Values
LED Brightness and Frequency Detection
Command ModeAllows flexible adjustment of values for users to precisely simulate real-world conditions.
Allows users to set the brightness range and the maximum pulse count within a specified time for DUTs' LED pulses, helping verify whether the LED under test meets the manufacturer's specifications.
Automatically generates test command scripts during testing. Users can edit the testing sequence and save it as a "Command file" for future tests.
Highlights
Provided SDK for Flexibly Developing Programs as Needed
- Users can develop automated testing software based on their needs to control the testing process, reducing the effort of repetitive setups
| Parameters | Supported Range / Types | Accuracy |
|---|---|---|
| BPM (1) | 30 ~ 300BPM (PC software); 30 ~ 240BPM (Standalone usage) | ±1BPM |
| DC - Main Mode | 1 ~ 20 Level | N/A |
| DC - Fine Tune Mode | 100mV ~ 2500mV | ±5mV |
| PI - Main Mode | 0.1% ~ 20% (AC / DC, differs with DC level) | N/A |
| AC - Fine Tune Mode | 0.75mV ~ 25mV | ±3% |
| Lumen (2) | 50 ~ 800Lux (5mm from diffusion film) | ±3% |
| Light Wavelength | 525nm | ±10nm |
| PD Sampling Rate (3) | <8 ksps (Normal Mode of software); 30 ksps (High Resolution Mode of software) | ±5μS |
| S/N Ratio | >51dB (with USB isolator) | N/A |
| Power - USB | USB Type-B Plug connector, DC 5V IN | N/A |
| Power - Battery | Type AA battery x 3 | N/A |
| Size (L x W x H) | 6.12cm x 13.5cm x 7.6cm | N/A |
| Temperature | 10 °C ~ 40 °C | N/A |
Note:
(1) Heart rate test range is different in standalone mode and PC mode. In PC software mode, heart rate range is from 30 to 300BPM; in standalone mode, heart rate value can be set to 30, 60, 70, 80, 90, 120, 150, 180, 210, 240BPM, plus user can manually select other 3 values from 30 to 300BPM as preset parameters.
(2) Lumen accuracy would be ±10Lux when the light source is lower than 400Lux.
(3) We suggest users to observe PD's analog signals via connecting HRS100+'s BNC port to an oscilloscope. Under High Resolution Mode, users need to check “LED Off” option to switch off HRS100+'s LED and no optical signals will be sent then.
