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.

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.
