Parallax PIR Sensor with LED Signal Brand_Gicren and can easily use serialThis PIR Sensor detects motion by measuring changes in the infrared (heat) levels emitted by surrounding objects. When motion is detected the build in LED lights up the lens dome as a visual signal, and the module also outputs a high signal on its output pin. This is the latest revision B version of this sensor, which includes the following improvements: Longer detection range, selectable by an onboard jumper Wider supply voltage, from 3 to 6 VDC
