UAV-R121-1(UART)Obstacle Avoidance Radar is a tiny & light millimeter wave obstacle avoidance radar sensor, which is self-designed and manufactured by MicroBrain Intelligent. It has advantages of high precision, small body, high sensitive, light weight, easy for integration and stable performance. This product can distinguish whether there’s obstacle ahead or not by forward sending fan-shaped 79GHz electromagnetic wave and dealing with the returned signals. It will send back the relative distance, speed and angle data between obstacles and radar to make the drone keep away from obstacles and ensure its safe working Note: For more technical details go through datasheet in the attachment section

Features:

  1. Detection Angle: The sensor might have a defined detection angle, specifying the breadth of its coverage area.
  2. High Accuracy: Precision is crucial for obstacle avoidance, so the sensor would likely boast high accuracy in detecting obstacles.
  3. Fast Response Time: Rapid response time is essential to quickly maneuver the UAV away from detected obstacles, minimizing the risk of collision.
  4. Compact Size and Lightweight: To minimize the impact on the UAV's overall weight and aerodynamics, the sensor would likely be designed to be compact and lightweight.
  5. Low Power Consumption: Efficiency is key, so the sensor might be designed to consume minimal power, extending the UAV's flight time.

Package Includes:

1 x Obstacle Avoidance Radar Sensor (UAV-R121-1) UART

Setup Guide

1
Identify the pins
Locate VCC (power), GND (ground), and data pins (SDA/SCL for I2C, MOSI/MISO for SPI, or TX/RX for UART). Refer to the pinout diagram on the product page.
2
Wire to your microcontroller
Connect VCC to 3.3V or 5V (check the module spec), GND to GND, and data pins to the appropriate GPIO pins on your Arduino or Raspberry Pi.
3
Install libraries
In Arduino IDE, go to Sketch → Include Library → Manage Libraries and search for the sensor library. Install the recommended version.
4
Upload example sketch
Open File → Examples → [library name] → Basic Example. Upload to your board and open Serial Monitor to view output.
5
Calibrate if needed
Some sensors (temperature, humidity, distance) may need a short warm-up period or calibration. Run the calibration sketch if provided.
