6.4. Energy Saving Application
Based on this radar motion target detection and biometric detection, the
radar can have better applications in energy saving control, the main
application modes are as follows:
• Energy saving for home appliances
• Energy saving controls for office appliances
• Energy saving control for street lighting
7. Notes
7.1. Start-up Time
As the module requires a complete reset of the module's internal circuitry
and a full assessment of the ambient noise when it is initially powered up
and started to work, the module can only be guaranteed to work properly.
Therefore the module needs a power-on stabilisation time of ≥ 30s at initial
power-up operation to ensure the validity of the subsequent output
parameters.
7.2. Effective Detection Distance
The detection distance of the radar module is highly dependent on the target
RCS and environmental factors, and the effective detection distance may
change as the environment and the target change.
7.3. Radar Bio-detection Performance
As human biometric features are ultra-low frequency, weakly reflective
signals, radar processing requires a relatively long period of cumulative
processing, and many factors may affect the radar parameters during the
cumulative process, so occasional detection failures are normal.
