The difference between infrared induction and microwave induction: A: infrared induction B: microwave induction
Inductive object:
A moving person or warm-blooded animal
B moving object
Installation method:
The A-infrared lens needs to be exposed and cannot be blocked by any object. Need to be installed on a stationary object.
B is installed inside the product and can penetrate the outer casing except metal. Need to be installed on a stationary object.
Ambient temperature:
When the ambient temperature and product temperature reach 36 °C or above, the sensing distance will be reduced by about 30%. Working temperature -20-+70°C
B ambient temperature and product temperature have no effect. Working temperature -20-+70°C
Induction direction:
A lateral sensitivity of the sensor is better. Moving positively or backwards to the sensor, the sensitivity is slightly worse.
The direction of B movement does not affect the sensitivity.
Drying factors:
A hot and cold air convection, wind. Power fluctuations, electromagnetic high frequency signals.
B. In the sensing area, multiple modules (except XC508) have power fluctuations and electromagnetic high-frequency signals.
Working power consumption:
A is less than 50 UA, available battery.
B is less than 3MA and requires a power supply.
Installation Environment:
A Avoid installing near window openings, air conditioning ports, vents, and heat sources. Try to prevent rain and direct sunlight.
B Avoid installation in high-frequency, electromagnetic, vibrating objects, empty places, the distance will be attenuated.
