PIR Sensors Used in Security Alarms and Automatic Lighting Applications D205B

Overview

D205B is widely used for ceiling lamps and has a large detection angle.The pyroelectric infrared sensor detects infrared radiation on the basis of the characteristics that the polarization of pyroelectric material changes with temperature.

Senba is the specialist PIR manufacturer for more than 15 years. We are the most advanced factory with complete categories. With strong R&D center, there are digital type and analog type, dual elements and four elements for you choose. The market cover domestic market, Korean, America, Turkey and Europe.

FAQ
1. Can PIR sensor detect animals?
PIR sensors are excellent in human and animal detection. They are mostly used in triggering an intruder alarm and activate household appliances upon the presence of a human.
 
2. Do PIR sensors work through glass?
No, alarm motion sensors do not work through glass. Most motion sensors use passive infrared (PIR) technology to detect motion. Changes in IR energy are not easily detected through glass. This is why motion sensors will generally not work through windows, which are usually insulated.
