The combination of an HC-SR04 Ultrasonic distance sensor and an MG90S micro servo creates an Arduino-compatible radar kit, where users can control the servo with an Arduino board while reading the HC-SR04 ultrasonic distance output. The resulting output can be combined with a serial reader program in Python on virtually any computer (including a Raspberry Pi!) to create a DIY radar sensor.

Included in the Radar Kit:

• 1x HC-SR04 Ultrasonic Distance Sensor

• 1x MG90S Micro Servo Motor

• 3x 3D-Printed Bracket for Mounting

• 6x Servo Hardware (3 screws for mounting, and 3 horns)

• 9x Jumper Wires for Connecting to an Arduino Board

• 3x Rubber Stoppers for stability

Features of the Radar Kit:

• ~20 Hz Update Rate

• Distance Measurements up to 4m

• Rotation Arc: 0° - 180°

• Arduino and Raspberry Pi Compatible
