HRXL-MaxSonar-WRT
The driver also offers back-EMF feedback
This time-of-flight (TOF) measurement enables it to accurately determine the absolute distance to a target 0 cm to 10 cm away with 1 mm resolution
250 inch (6
finer resolution can be achieved with microstepping
QTR-HD-11RC Reflectance Sensor Array TFT Display HRXL-MaxSonar-WRTThis array of IR LED phototransistor pairs is great for precisely identifying changes in reflectance (like line detection). It operates from 2. 9 V to 5. 5 V and offers dimmable brightness control independent of the supply voltage and separate controls for the odd and even emitters. In general, the closer the object, the higher the contrast between light and dark readings, but high reflectance objects are generally detectable out to around 40 mm. This
