SparkFun PIR Breakout - 170uA (EKMC4607112K)

The SparkFun EKMC4607112K PIR Breakout is a compact, efficient Passive Infrared (PIR) sensor, specifically designed for detecting motion within a small area. Equipped with a Panasonic EKM-series PIR sensor, this board is optimized to detect even the smallest movements, making it an excellent choice for continuously powered applications.

The SparkFun EKMC4607112K PIR Breakout doesn't provide specific distance data but instead monitors for infrared light from objects within its field of view. It activates its signal when motion is detected in its sensing area. This feature makes it ideal for applications such as automated on/off lighting control, home and building automation for energy saving, security, appliances, and IoT.

The Panasonic PIR motion sensors on the SparkFun EKMC4607112K PIR Breakout are low-profile (10.9mm as opposed to the standard 14.4mm height), offering space savings for constrained designs. The sensor comprises 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 provides digital output across 32 zones at a 5m detection distance with a 90° x 90° detection area.

Please note that the sensitivity of passive infrared sensors is influenced by environmental conditions. Therefore, a performance evaluation test under representative conditions is recommended.

The SparkFun EKMC4607112K PIR Breakout operates at a voltage between 3.3V and 6.0V, with a standby current consumption of 170 µA. The lens diameter is 10.4mm, and the lens height is 10.9mm. The detection distance is 5m, with a 90° x 90° (±45°) detection area.
