Wire the mmWave sensor to D2 and D3 on the XIAO, choose your development path (Arduino or TinyGo), and load the provided sample sketch.

Frequently Asked Questions about xiao-accessory-mmwave24ghz

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I connect a 24GHz mmWave sensor to a Seeed XIAO board for presence detection?▼

To connect a 24GHz mmWave sensor for presence detection, wire the sensor to the D2 and D3 UART pins on the XIAO board. This setup requires 5V power and enables UART communication for human static presence and motion detection.

Can I use TinyGo and Arduino to program the mmWave sensor on XIAO?▼

Yes, you can use both Arduino and TinyGo to program the 24GHz mmWave sensor on XIAO. The integration provides setup instructions and sample sketches for both development environments to facilitate firmware development.

What is the best way to configure parameters on a 24GHz FMCW mmWave presence sensor?▼

The best way to configure parameters on a 24GHz FMCW mmWave presence sensor is via Bluetooth using the HLKRadarTool. This enables parameter tuning and secondary development to fine-tune presence and motion detection.

Does the 24GHz mmWave presence sensor require 5V power when integrated with XIAO?▼

Yes, the 24GHz mmWave presence sensor requires 5V power when integrated with XIAO boards. Proper 5V power is necessary alongside the D2/D3 UART connections for reliable occupancy and motion detection.

Why use a 24GHz FMCW mmWave sensor for human static presence detection?▼

A 24GHz FMCW mmWave sensor is used for human static presence detection because it accurately identifies occupancy and motion via UART. It supports XIAO microcontroller integration for continuous presence monitoring.
