SparkFun Qwiic PIR Starter Kit (170µA)
SparkFun Qwiic PIR Starter Kit (170µA)
Description
The SparkFun Qwiic PIR Starter Kit (170µA) comes w/ just the basics of what you need to get started working w/ passive infrared (PIR) sensors. Passive Infrared (PIR) sensors are great for detecting motion in a small area around the sensor. The 1µA SparkFun EKMC4607112K Qwiic PIR uses an EKM-series PIR sensor paired w/ an ATTiny84 to interact w/ it using I2C w/ the Qwiic system. The EKMB-series PIR sensors are optimized for small movements to offer motion- sensing options for battery-powered applications continuously powered applications.PIR sensors do not return specific distance data but instead monitor for IR light coming from objects in their field of view & will activate their signal when motion is detected in their sensing area, making them perfect for applications such as turning devices on automatically when motion is detected. Applications include home & building automation for energy saving, automated on/off lighting control, security, appliances, & IoT.These 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, & an impedance converter to get an electrical signal. This PIR sensor offers digital output across 32 zones at 5m detection distance w/ 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.Also included in this kit is a SparkFun RedBoard Qwiic to drive your PIR sensor. The SparkFun RedBoard Qwiic can be programmed over a USB Micro-B cable (included) using the compatible with Arduino IDE: Just plug in the board, select "UNO" from the board menu & you're ready to upload code. To hookup your PIR sensor to your RedBoard we have included a 100mm length Qwiic cable.
