描述

SparkFun OpenPIR 超低功耗 人體紅外感應模組 NCS36000 PIR 被動紅外 (PIR) 感測器

SparkFun OpenPIR 是一款高度可定制的被動紅外 (PIR) 傳感器，基於 NCS36000 PIR 控制器。無源紅外 (PIR) 傳感器能夠檢測小範圍/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首選傳感器。OpenPIR 允許您設置運動傳感器的靈敏度、觸發時間和脈沖模式，以便根據您的應用量身定制！

OpenPIR 具有許多獨特的特性，包括用於調整靈敏度（視距）的兩個微調器和用於控制輸出保持高電平時間長度的振盪器，以及支持兩種運動檢測模式的觸發器：單脈沖和雙脈衝。此外，每個 OpenPIR 都配備了一個反向進入的綠色 LED，它複製了 OUT 引腳的狀態。當檢測到運動時，LED 將亮起；否則它將保持關閉狀態。

SparkFun OpenPIR 在 80µA 待機時支持 3VDC 至 5.75VDC 的電源範圍（檢測運動時為 3mA），並且能夠通過標準 0.1″ 接頭或 4 針 JST PH 連接器進行連接。

SparkFun OpenPIR

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.
