The SparkFun OpenPIR is a highly customizable Passive Infrared (PIR) sensor based around the NCS36000 PIR controller. Passive infrared (PIR) sensors are able to detect motion in a small/local area –– they’re the sensor of choice in security systems, home automation and proximity-sensing applications. The OpenPIR allows you to set the sensitivity, trigger time and pulse mode of the motion sensor so you can tailor-fit it to your application!
The OpenPIR has a multitude of characteristics unique to itself, including two trimpots to adjust sensitivity (view distance) and the oscillator to control the length of time the output remains HIGH, as well as a trigger that supports two motion-detection modes: single-pulse and dual-pulse. Additionally, each OpenPIR is equipped with a reverse-entry green LED, which duplicates the status of the OUT pin. When motion is detected, the LED will illuminate; otherwise it will remain off.
The SparkFun OpenPIR supports a power supply range of 3VDC to 5.75VDC at 80µA standby (3mA when detecting motion) and is able to be connected via a standard 0.1" header or a 4-pin JST PH connector.

SparkFun OpenPIR是一種基於NCS36000 PIR控制器的高度可定制的被動紅外(PIR)傳感器。無源紅外(PIR)傳感器能夠檢測小/局部區域的運動 - 它們是安全系統,家庭自動化和接近感應應用中的傳感器。 OpenPIR允許您設置運動傳感器的靈敏度,觸發時間和脈沖模式,以便您可以根據您的應用進行定制。
OpenPIR具有眾多獨特的特性,包括兩個微調點來調節靈敏度(視距)和振盪器來控制輸出保持高電平的時間長度,以及支持兩種運動檢測模式的觸發器:脈沖和雙脈衝。另外,每個OpenPIR都配有一個反向輸入綠色LED,它與OUT引腳的狀態重複。當檢測到運動時,LED將亮起;否則它將保持關閉。
SparkFun OpenPIR支持80μA待機時的3VDC至5.75VDC電源範圍(檢測運動時為3mA),並且可以通過標準0.1“接頭或4針JST PH連接器進行連接。
