PIR vs. mmWave Sensors for Home Automation
Two popular options for motion detection in smart home systems are Passive Infrared (PIR) sensors and millimeter wave (mmWave) sensors. Each technology comes with its own set of advantages and drawbacks, making them suitable for different applications depending on the specific needs of homeowners. Let's delve into the pros and cons of each:
