Frequently Asked Questions:

Q1. What makes the MICROBRAIN H31-1 radar ideal for agricultural spraying drones?

Ans. The MICROBRAIN H31-1 radar is ideal for agricultural spraying drones due to its highly accurate 2cm height measurement and 77GHz frequency band, enabling precise terrain following. This ensures the drone maintains a consistent spray height above crops, regardless of ground undulations, leading to uniform application of pesticides or fertilizers. Its IP67 rating also guarantees reliable performance in dusty and wet agricultural environments.

Q2. How does the 77GHz frequency of the H31-1 compare to 24GHz radars often found on drones?

Ans. The 77GHz frequency of the MICROBRAIN H31-1 radar offers several advantages over common 24GHz drone radars. Generally, higher frequencies allow for smaller antenna sizes, higher measurement accuracy (2cm for H31-1), and better resolution for distinguishing between closely spaced objects or ground features. While 24GHz is robust, 77GHz can provide more precise data crucial for demanding applications like accurate terrain following over crops or complex landscapes.

Q3. Is the MICROBRAIN H31-1 Terrain Radar compatible with open-source flight controllers like Pixhawk or Ardupilot?

Ans. Yes, the MICROBRAIN H31-1 Terrain Radar is designed to be compatible with popular open-source flight controllers such as Pixhawk and Ardupilot. It uses a UART (serial port) communication interface, which is widely supported by these flight controllers. Users typically need to connect the sensor's UART pins to an available serial port on the flight controller and configure the appropriate parameters in the flight controller's firmware to enable terrain following functionality.
