Passive Infrared (PIR) sensors are great for detecting motion in a small area around the sensor. This is an EKM-series PIR sensor from Panasonic®. The EKMB-series PIR sensors are optimized for small movements to offer motion-sensing options for battery powered applications due to the low standby current draw of the sensor (1µA).
Panasonic's low-profile PIR motion sensors (10.9mm versus standard 14.4mm height offer space savings for constrained designs) consist of a lens to create various detection zones, an optical filter to block non-infrared light, pyroelectric sensing elements, electromagnetic shielding to all circuitry, and an impedance converter to get an electrical signal. This PIR sensor offers digital output across 32 zones at 5m detection distance with 90° x 90° detection area.
Note: The sensitivity of passive infrared sensors is influenced by environmental conditions, so a performance evaluation test under representative conditions is recommended.
