Q7: Can the solar street lamp be used in high&low temperature area and strong wind environment?
A: Of course yes, as we take Aluminum-alloy holder, solid and firm, Zinc plated, anti- rust corrosion.
Q8: What's the difference between Motion sensor and PIR sensor?
A: Motion sensor also called radar sensor, works by emitting high frequency electric wave and detecting people movement. PIR sensor works by detecting environment temperature changing, which usually is 3-8 meters sensor distance. But motion sensor can reach 10-15 meters distance and be more accurate and sensitive.
