Ambient Light Sensor Selection Guide
This section provides a quick reference for selecting different light sensors based on their spectral sensitivity, illuminance range, and output type. It also includes typical illumination levels in common environments to help users choose the most suitable sensor.
Sensor Selection Guide
The following information is only for qualitative reference.
| Sensor SKU | Relative Spectral Sensitivity | Illuminance Range | Output(VCC=5V) |
|---|---|---|---|
| SEN0043（TEMT6000） |  |
1-5000lx | analog voltage:0-5V |
| SEN0097（BH1750） |  |
1-65535lx | digital:I2C,with Low Fitler(<50Hz) |
