Maker Line is een lijnsensor met 5 x IR sensoren array die in staat is om lijnen te volgen van 13 mm tot 30 mm breedte.
De sensor calibratie is ook vereenvoudigd. Het is niet nodig om de potentiometer voor elke IR sensor aan te passen. U hoeft alleen maar de calibrate knop gedurende 2 seconden in te drukken om de calibratie modus te openen. Daarna moet u de sensoren over de lijn laten vegen, nogmaals op de knop drukken en u bent klaar om te gaan.
De kalibratiegegevens worden opgeslagen in EEPROM en deze blijven intact, zelfs als de sensor is uitgeschakeld. Kalibratie hoeft dus maar één keer te worden uitgevoerd, tenzij de sensorhoogte, lijnkleur of achtergrondkleur is veranderd.
Maker Line ondersteunt ook dubbele uitgangen: 5 x digitale uitgangen voor de status van elke sensor onafhankelijk, wat vergelijkbaar is met conventionele IR-sensor, maar u krijgt het voordeel van eenvoudige kalibratie, en ook een analoge uitgang, waar de spanning de lijnpositie vertegenwoordigt. De analoge uitgang biedt ook een hogere resolutie in vergelijking met afzonderlijke digitale uitgangen. Dit is vooral nuttig wanneer een hoge nauwkeurigheid vereist is bij het bouwen van een lijnvolgende robot met PID regeling.
Kenmerken
Bedrijfsspanning: DC 3,3 V en 5 V compatibel (met omgekeerde polariteitsbeveiliging)
Aanbevolen lijndikte: 13 mm tot 30 mm
Selecteerbare lijnkleur (licht of donker)
Sensor afstand (hoogte): 4 mm tot 40 mm (Vcc = 5 V, zwarte lijn op wit oppervlak)
Sensor Vernieuwingsfrequentie: 200 Hz
Eenvoudig kalibratieproces
Dubbele uitgangstypen: 5 x digitale uitgangen vertegenwoordigen elke IR-sensor staat, 1 x analoge uitgang vertegenwoordigt lijn positie.
Ondersteunt een breed scala aan controllers, zoals Arduino, Raspberry Pi etc.

Build your textbook weather station or conduct environmental research together with the whole world. With many practical projects for Arduino, Raspberry Pi, NodeMCU, ESP32, and other development boards.
Weather stations have enjoyed great popularity for decades. Every current and even every long discontinued electronics magazine has regularly featured articles on building your own weather station. Over the years, they have become increasingly sophisticated and can now be fully integrated into an automated home — although this often requires loyalty to an (expensive) brand manufacturer across all components.
With your own weather and environmental data, you can keep up and measure things that no commercial station can. It’s also fun: expand your knowledge of electronics, current microcontroller development boards and programming languages in a fun and meaningful way. For less than 10 euros you can get started and record your first environmental data — with time and growing interest, you will continue to expand your system.
