The HRLV-MaxSonar-EZ sensor line is the fastest way to get precision range-finding into your computer. No microcontroller or adapter required, simply connect any micro B USB cable (not included) into the sensor and install the FTDI drivers to get serial sonar distance data via serial on any computer operating system.The HR-USB-EZ sensor line provides high accuracy and high resolution ultrasonic proximity detection and ranging in air, in a package less than one cubic inch. This sensor line features 1mm resolution, target-size and operating-voltage compensation for improved accuracy, superior rejection of outside noise sources, internal speed-of-sound temperature compensation and optional external speed-of-sound temperature compensation. This ultrasonic sensor detects objects from 1mm to 5meters, senses range to objects from 30cm to 5meters, with large objects closer than 30cm typically reported as 30cm. https://elecena.pl/product/17498990/maxbotix-ultrasonic-rangefinder-hr-usb-ez1 2021-04-06 https://elecena.pl/product/17498990/maxbotix-ultrasonic-rangefinder-hr-usb-ez1 2022-04-14
