PIR Sensor with LED Signal

Product Description

Overview:

The PIR Sensor detects motion by measuring changes in the infrared (heat) levels emitted by surrounding objects. When motion is detected a LED lights up the lens dome as a visual signal, and the module also outputs a high signal on its output pin.

NOTE: The product information found on this page currently pertains to Revision B of this product, which provides many updates and features from Revision A. Some of these include:

• Longer detection range, selectable by onboard jumper
• Wider supply voltage, from 3 to 6 VDC
• Higher output current provides for direct control of an external load
• Mounting holes included for permanent projects
• All parts SMT

Key Features:

• Typically detects a person up to approximately 30 ft away, or up to 15 ft away in reduced sensitivity mode
• Jumper selects normal operation or reduced sensitivity
• Approximately 90 degree field of view
• LEDs light up the dome for visual signal of sensor activation
• Mounting holes for 2-56 sized screws provide easy integration in permanent applications
• 3-pin SIP package perfect for breadboard-friendly projects
• Easy communication with any microcontroller
• Small size makes it easy to conceal

Application Ideas:

• Motion-activted nightlight
• Alarm system
• Animated holiday props
