Maker Line est un capteur de ligne doté d'un réseau de 5 capteurs IR capable de suivre des lignes de 13 mm à 30 mm de largeur. L'étalonnage du capteur a également été simplifié. Il n'est pas nécessaire d'ajuster le potentiomètre pour chaque capteur IR. Il vous suffit d'appuyer sur le bouton de calibrage pendant 2 secondes pour accéder au mode de calibrage. Ensuite, vous devez faire glisser les capteurs sur la ligne, appuyer à nouveau sur le bouton et vous êtes prêt à partir. Les données d'étalonnage sont stockées dans l'EEPROM et restent intactes même lorsque le capteur est éteint. L'étalonnage ne doit donc être effectué qu'une seule fois, sauf si la hauteur du capteur, la couleur de la ligne ou la couleur de fond ont changé. Maker Line prend également en charge deux sorties : 5 sorties numériques pour l'état de chaque capteur indépendamment, ce qui est similaire au capteur IR classique, mais vous bénéficiez d'un étalonnage facile, et également une sortie analogique, où la tension représente la position de la ligne. La sortie analogique offre également une résolution plus élevée par rapport aux sorties numériques séparées. Ceci est particulièrement utile lorsqu’une grande précision est requise lors de la construction d’un robot suiveur de ligne avec contrôle PID. Caractéristiques Tension de fonctionnement : compatible DC 3,3 V et 5 V (avec protection contre l'inversion de polarité) Largeur de trait recommandée : 13 mm à 30 mm Couleur de ligne sélectionnable (claire ou foncée) Distance du capteur (hauteur) : 4 mm à 40 mm (Vcc = 5 V, ligne noire sur surface blanche) Taux de rafraîchissement du capteur : 200 Hz Processus d'étalonnage facile Types de sortie double : 5 sorties numériques représentent chaque état du capteur IR, 1 sortie analogique représente la position de la ligne. Prend en charge une large gamme de contrôleurs, tels que Arduino, Raspberry Pi, etc. Téléchargements Fiche de données Tutoriel : Construire un robot de suivi de ligne bon marché

STmicroelectronics’ wireless IoT & wearable sensor development kit ‘SensorTile.box’ is a portable multi-sensor circuit board housed in a plastic box and developed by STMicroelectronics. It is equipped with a high-performance 32-bit ARM Cortex-M4 processor with DSP and FPU, and various sensor modules, such as accelerometer, gyroscope, temperature sensor, humidity sensor, atmospheric pressure sensor, microphone, and so on. SensorTile.box is ready to use with wireless IoT and Bluetooth connectivity that can easily be used with an iOS or Android compatible smartphone, regardless of the level of expertise of the users. SensorTile.box is shipped with a long-life battery and all the user has to do is connect the battery to the circuit to start using the box. The SensorTile.box can be operated in three modes: Basic mode, Expert mode, and Pro mode. Basic mode is the easiest way of using the box since it is pre-loaded with demo apps and all the user has to do is choose the required apps and display or plot the measured data on a smartphone using an app called STE BLE Sensor. In Expert mode users can develop simple apps using a graphical wizard provided with the STE BLE Sensor. Pro mode is the most complex mode allowing users to develop programs and upload them to the SensorTile.box. This book is an introduction to the SensorTile.box and includes the following: Brief specifications of the SensorTile.box; description of how to install the STE BLE Sensor app on an iOS or Android compatible smartphone required to communicate with the box. Operation of the SensorTile.box in Basic mode is described in detail by going through all of the pre-loaded demo apps, explaining how to run these apps through a smartphone. An introduction to the Expert mode with many example apps developed and explained in detail enabling users to develop their own apps in this mode. Again, the STE BLE Sensor app is used on the smartphone to communicate with the SensorTile.box and to run the developed apps. The book then describes in detail how to upload the sensor data to the cloud. This is an important topic since it allows the sensor measurements to be accessed from anywhere with an Internet connection, at any time. Finally, Pro mode is described in detail where more experienced people can use the SensorTile.box to develop, debug, and test their own apps using the STM32 open development environment (STM32 ODE). The Chapter explains how to upload the developed firmware to the SensorTile.box using several methods. Additionally, the installation and use of the Unicleo-GUI package is described with reference to the SensorTile.box. This PC software package enables all of the SensorTile.box sensor measurements to be displayed or plotted in real time on the PC.
