Hi would like to use a cheap mm wave sensor for use with home assistant. Does the product below work with home assistant? Is there any tutorials on implementing it to use its features in HA. > **[Human Micro-Motion Detection mmWave Sensor](https://core-electronics.com.au/human-micro-motion-detection-mmwave-sensor.html?registered=1)** > > Human Micro-Motion Detection mmWave Sensor, 24GHz mmWave Radar, Based On S3KM1110, Adopts Frequency Modulated Continuous Wave (FMCW) Technology, Compact... ---

The warning label on the web page needs to specify 24GHz devices, at present it lists only the lower frequencies (433Mhz / 915-930Mhz / 2.4Ghz). Any purchasers of this product should be aware of the ACMA regulations in Australia and ensure operation does not breach these regulations. [https://www.acma.gov.au/licences/low-interference-potential-devices-lipd-class-licence](https://www.acma.gov.au/licences/low-interference-potential-devices-lipd-class-licence) Regards Jim PS Waveshare do not specify the power output which is a problem in my book, ACMA states a maximum EIRP of 0.1W. ---

Most likely not. You will need something that reads the UART signal and translates it to whatever format Home Assistant needs. ---

Hi @Daniel193519 That sensor would be similar to our [Rd-03D mmWave Multi-Human Position Sensor | Buy in Australia | CE10172 | Core Electronics](https://core-electronics.com.au/mmwave-sensor-rd03d-presence-detection-sensor.html) that was featured in this write up [Detect and Track Humans with mmWave Radar on an Arduino](https://forum.core-electronics.com.au/t/detect-and-track-humans-with-mmwave-radar-on-an-arduino/22417). There is definitely a good chance that it’s possible, but as @James46717 mentioned you will need something to interpret the UART signal into a digestible input for HA. We haven’t had a chance to see if it will work or not, and there is limited info available for doing so online. I would say your best bet will be to use an LLM such as chatgpt and run some tests with it. ---

Hi Daniel, If your question is whether it will work directly with Home Assistant, then no, it can’t really communicate other than by the GPIO. However, if you use connect it to a ESP32 GPIO, from the spec sheet: high means presence detected, low mean no detection. This is no different to a PIR sensor. The ESP32 integrates fairly seamlessly with HA using the ESP32Home integration. I’ve used these: [https://core-electronics.com.au/esp32-c3-mini-dev-board-iot-wifi-bluetooth.html](https://core-electronics.com.au/esp32-c3-mini-dev-board-iot-wifi-bluetooth.html) to connect a few PIRs. In the .yaml code treat it as a binary sensor. After you do the details for the WiFi connection, the snesor only needs a small amount of code like this: ```auto binary_sensor: - platform: gpio pin: number: 4 mode: input: True pullup: False name: "SensorName" ``` Good luck, Dave ---

Hey @David173576 Good pickup with the GPIO out pin! ---

This _ **looks** _ identical to the [LD2420 24GHz mmWave Radar Sensor](https://esphome.io/components/sensor/ld2420) in ESPHome, and discussed in [LD2410C vs 2410B vs LD2410S vs 2411 vs HLK-LD2420 vs LD2450 - Hardware - Home Assistant Community](https://community.home-assistant.io/t/ld2410c-vs-2410b-vs-ld2410s-vs-2411-vs-hlk-ld2420-vs-ld2450/652599) However Hi-Link state LD2410S uses the ICL1112 chip - whereas Waveshare’s wiki indicates the WS26536 uses the Silicon Micro AIoT Millimeter-Wave Sensor SoC S3KM1110.
