Infrared: 1. The product sensing probe must be exposed to affect the appearance and light distribution effect of the lamp;
2. The sensitivity of the internal pyroelectric probe is decreasing year by year, which shortens the sensing distance year by year;
3. Poor stability relies on the difference between human body temperature and ambient temperature and movement to achieve detection.
Therefore, the environmental requirements are high and the sensing range is doubled in high temperature environments in summer;
4. The lithium Phil lens is made of plastic, which easily accumulates dust and will age year by year, causing the sensitivity to decrease.
Microwave: 1. The microwave module is built into the lamp tube and does not affect the appearance of the lamp and the light distribution of the lamp;
2. It is not affected by temperature, noise, humidity, dust, etc. Suitable for various environments with high stability;
3. Long service life, high sensitivity, and will not change with age.
