Me Ultrasonic Sensor
Specifications:
Operating Voltage: 5V DC
Detecting Range: 3cm-400cm
Detecting Angle: Prefer at 30 degree angle
Dimension (L*W*H): 56 x 36 x 31mm
Me Ultrasonic Sensor is an electronic module that emits an ultrasonic wave and determines the distance
between the sensor and an object based on the time it takes to send the signal and receive the echo. Ultrasonic
sensors have numerous applications, such as parking assistance sensors in cars and proximity alarms. This Me
Ultrasonic Sensor can be attached to the port with yellow tags on Me Auriga.

Me Line Follower Sensor
Specifications:
Operating Voltage: 5V DC
Detecting Range: 1~2cm
Dimension (L*W*H): 48 x 24 x 24mm
Me Line Follower module is designed for giving the robot the ability to detect lines or nearby objects. It has two
sensors on the module and each sensor contains two parts - an IR emitting LED and an IR sensitive phototrans-
istor. By measuring the amount of reflected infrared light, it can detect transitions from light to dark (lines) or
even objects directly in front of it. This module can be connected to the port with blue tags on Me Auriga.
