Product description
Passive Infrared (PIR) sensors are great for detecting motion in a small area around the sensor. The 170µA SparkFun EKMC4607112K Qwiic PIR uses an EKM-series PIR sensor from Panasonic paired with an ATTiny84 to interact with it using I2C with the Qwiic system. The EKM-series PIR sensors are optimized for small movements to offer motion-sensing options for continuously powered applications.
Panasonic's low-profile PIR motion sensors 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.
