PIR Wide Angle Sensor
Price: $10.99 In Stock
Item #: KIT-00081 -

    The PIR(Passive Infra-Red) Sensor is a pyroelectric device that detects motion by sensing changes in the infrared(radiant heat) levels emitted by surrounding objects. Product Features Single bit output Small size On-board LEDs Power 3V to 6VDC operation 150uA idle, 3mA active(no load) current draw 30mA active(0 ohm resistor) high current draw Detect a person up to 30 ft away 180┬░wide detect angle Sensitivity adjustable On-board light sensor, night enable mode 4-pin SIP header with...

    Parallax PIR Motion Sensor
    Price: $9.99 Back Order
    Item #: PX-555-28027 -

      The PIR Sensor detects motion up to 20 feet away by using a Fresnel lens and infrared-sensitive element to detect changing patterns of passive infrared emitted by objects in its vicinity. Inexpensive and easy to use, it's ideal for alarm systems, motion-activated lighting, holiday props, and robotics applications. The PIR Sensor is compatible with all Parallax microcontrollers; sample BS1, BS2, and SX/B programs and product documentation are available under Downloads (coming soon!). Features:...

        This sensor is intended to be used with a Phidget Interface Kit 8/8/8 (Analog input). This sensor detects changes in infrared radiation which  occur when there is movement by a person (or object) which is different in temperature from the surroundings. As this sensor detects temperature differences, it is well suited to detecting the motion of people by their body temperature. The sensor is also characterized by a narrow sensing area. This kit includes (1) Phidget Motion Sensor and (1)...
