Sharp IR Distance Sensor GP2Y0A41SK0F (4-30CM)
Price: $13.95 In Stock
Item #: DK-GP2Y0A41SK0F -

    The Sharp IR Distance Sensor GP2Y0A41SK0F is a great low cost robotic range-finder. The Distance Sensor will report the presence of an object 4-30cm away from the sensor. The sensors reports this data as an analog value readable by most microcontrollers, like the Arduino. This sensor can plug directly into a RobotGeek Sensor Shield using a Sharp IR to Servo Cable. This cable can also be handy to connect to other systems and controllers (users can cut/splice the wire). If you want to use this...

    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.Each Wide Angle PIR Sensor cable includes a 4-pin cable, as well as a mount and hardware to adapt to all RobotGeek products with a centimeter grid pattern (Workbenches, Geekbot, etc.). Mount it at a right angle, and flat.Product FeaturesSingle bit output Small size On-board LEDs Power 3V to 6VDC operation 150uA idle, 3mA active(no...

      Sharp IR Distance Sensor - GP2D12 Alternative (10-80 cm) Sharp, IR, Distance, Sensor, GP2D12, (4-30 inches)
      Price: $12.95 In Stock
      Item #: PX-28995 -

        One of the most favored IR range sensors on the market. Detects distances from 4" to 30" (10cm-80cm). Note: The sensor sold here is actually a Sharp IR GP2Y0A21YK0F. It has the same distance range as a GP2D12 and very similar analog output properties. The GP2D12 is extremely difficult to source currently, so these sensors provide a great alternative. For more information on the minor differences, please refer to the datasheets for each sensor: Datasheets GP2D12 Datasheet GP2Y0A21YK0F...

        Sharp IR Distance Sensor GP2Y0A02YK (20-150 cm)
        Price: $15.00 In Stock
        Item #: PO-1137 -

          This sensor takes a continuous distance reading and reports the distance as an analog voltage with a distance range of 20cm (~8") to 150cm (~60"). The interface is 3-wire with power, ground and the output voltage and requires a JST 3-pin connector (not included). The JST 3-pin connector includes the J3 connector for the sensor and bare wires at the other end, and requires that the processor or ADC-side connector be purchased or built separately. For most applications we recommend...

          Parallax PIR Motion Sensor
          Price: $9.99 In Stock
          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:...

            GP2D12 - Sharp IR Sensor to Servo Cable
            Price: $1.95 In Stock
            Item #: RC-IR_Cable -

              This cable adapts from the JST connector found on the Sharp IR sensors to a standard 3-pin servo-style connector.  This is compatible with many robot controller boards, such as those used in the Robonova and KHR humanoids.
