Needs technical knowledge
The sensor works, but the documentation for the configuration tool was a bit sparse. Expect some learning curve if you are new to radar.

Reliable Detection
Tested through a thin plastic enclosure. Still detects motion and presence accurately. Much better than infrared solutions.

Low power indeed
Running on battery power for a project. The sleep mode consumption is incredibly low as specified. Great for IoT.

Good sensitivity
Works well for my bathroom light switch. Had to tweak the sensitivity settings via UART to avoid false positives from the fan.

Perfect for Home Automation
Integrated this with my ESPHome setup. Detects presence even when sitting still, unlike PIR sensors. Very happy with the purchase.
Q: Does it require a separate programmer?
A: No, you can configure it via UART using a USB-to-TTL adapter and the provided configuration software.
Q: What is the maximum detection distance?
A: The maximum range is up to 8 meters in an open environment, but this varies based on configuration and obstacles.
Q: Is it compatible with Arduino?
A: Yes, it communicates via UART TTL, so it works with Arduino, ESP32, and ESP8266 boards.
Q: Can it distinguish between humans and pets?
A: It is optimized for human presence detection. Small pets may trigger it depending on sensitivity settings and distance.
Q: Can this detect through a wooden door?
A: It can detect through thin non-metallic materials like thin wood or plastic, but thick walls will block the signal.
