This is a simple to use motion sensor. Power it up and wait 1-2 seconds for the sensor to get a snapshot of the still room. If anything moves after that period, the ‘alarm’ pin will go low.

This unit works great from 5 to 12V (datasheet shows 12V). You can also install a jumper wire past the 5V regulator on board to make this unit work at 3.3V. Sensor uses 1.6mA@3.3V.

The alarm pin is an open collector meaning you will need a pull up resistor on the alarm pin. The open drain setup allows multiple motion sensors to be connected on a single input pin. If any of the motion sensors go off, the input pin will be pulled low.

We’ve finally updated the connector! Gone is the old “odd” connector, now you will find a common 3-pin JST! This makes the PIR Sensor much more accessible for whatever your project may need. Red = Power, White = Ground, and Black = Alarm.

這是一個簡單的使用運動傳感器。接通電源並等待1-2秒的傳感器來獲取仍有空間的快照。如果任何時間後移動時,“報警”腳將變低。

這個單位從5至12V的偉大工程(數據表顯示12V)。您也可以過去5V穩壓器在船上安裝跳線,使在3.3V本單位的工作。傳感器採用1.6mA@3.3V。

報警引腳是一個集電極開路這意味著你需要使用報警引腳上拉電阻。漏極開路設置允許多個運動傳感器在單個輸入引腳相連。如果任何一個運動傳感器熄滅,輸入引腳將被拉低。

我們終於更新了連接器!逝去的是舊的“奇”的連接器,現在你會發現一個共同的3針JST!這使得紅外感應更接近不管是什麼項目需要。紅色=電源,白色=球場和黑色=報警。
