    Cobra Line Follower Sensor

    #70151
    $9.99

    The Cobra Line Follower Array provides 4 X QRE1113 IR reflectance sensor mounted on a 9mm pitch Each sensor is comprised of two parts - an IR emitting LED and an IR sensitive phototransistor. When you apply power to the VCC and GND pins the IR LED inside the sensor will illuminate.

    The Studica Line Sensor Board consists of 4 IR LED/phototransistor pairs, making it a great detector for a line-following robot.  The Line Sensor Board allows the robot to tell objects or surfaces apart based on how dark or light they are. It shines a beam of infrared light out onto the object, and measures how much light is reflected back.

    Each sensor provides a separate analog voltage output. The sensor board is an infrared emitter/receiver that is able to differentiate between a dark surface (with low IR reflectivity – 3.3V to 5V) and a light surface (with high IR reflectivity – 0V to 0.5V). However, this range can vary depended on the installed height of the sensor board. 

    The optimum height distance is 3-5 mm; however, the reflectivity values will change depending on distance. A daylight filter is built into the sensor.

    • 5VDC operating voltage (recommended)
    • 70mA supply current
    • Optimal sensing distance: 0.125" (3mm)

    Sharp IR Range Sensor (10cm to 80cm) w/wire

    #40117
    $13.99

    The Sharp IR Distance Sensor GP2Y0A21YK0F uses a beam of infrared light to reflect off an object to measure its distance. Because it uses triangulation of the beam of light to calculate the distance, it is able to provide consistent and reliable readings which are less sensitive to temperature variation or the object’s reflectivity. The sensor outputs an analog voltage corresponding to the distance of the object, and can easily be read using an inexpensive analog to digital converter (ADC) chip.

    Grove - Infrared Reflective Sensor v1.2

    #101020174
    $4.90
    Grove - Infrared Reflective Sensor v1.2 can be used for detection of proximity and color of objects. The reflective photosensor - RPR-220 used in this module consists of an infrared light emitting diode and a high –sensitivity phototransistor. Light-colored objects directly in front of the sensor will reflect more infrared light as well as generate more current in the phototransistor than an object with dark-colored surfaces, this can be tell from a built-in indicator LED which will turn red with sufficient flow of current. Also, the intensity of the reflective light increases as the object getting closer. You can adjust the potential-meter on the back of the board if you want to detect a specific object (eg. Black line) at a certain distance.

    fischertechnik Robotics Sensor Station IoT

    #FT-RSS-GP

    A professional introduction to data logging! The stationary sensor station with a moving camera, new environmental sensor and other sensors, enables the measurement of air temperature, humidity, air pressure, air quality, volume and brightness. The models can be programmed and controlled with the graphical programming software ROBO Pro and the ROBOTICS TXT controller, and are ideal for teaching topics such as (data logging, programming and the use of actuators and sensors. The sensors’ data can be collected and plotted on a graph. In addition, the model can connect to a WiFi network, so that the camera can also be controlled from a distance. The TXT controller can also be connected to a cloud server, where the sensors’ data is saved and can be retrieved. So using a user interface, a so-called “dashboard”, the various sensor data can be permanently monitored, and the movement of the camera can be controlled. Further models and applications the pupil can first design and then control are: Barometer (measures air pressure), Damp monitor (measures humidity and air temperature), environmental wellness sensor (measures the air quality, temperature, humidity) with LED display, noise sensor (measures volume) and frost monitor (tests temperature against the freezing point). When the pre-set limit values are exceeded, the system alerts the user via an LED display or with an alarm tone. There are many more possible applications. The innovative teaching material from fischertechnik supports you in practically conveying technical understanding and giving them a real insight. The accompanying instructional booklet, with teaching and lesson materials, offers background information, projects , and programmer tips.
