Introducing the Apollo MTR-1 for ESPHome, a multi target radar multisensor. The MTR-1 packs a diverse array of sensors in an affordable and compact package. With dimensions of 49mm by 32mm and a profile of just 15mm, this sensor can seamlessly integrate into any space. Multiple targets, zones, target coordinates, RGB, buzzer, LUX/UV, CO2 (optional) are all things the MTR-1 can measure.

Powered via USB-C and a standard wall plug, the device uses WIFI to connect to ESPHome on your Home Assistant install.

We proudly offer the software and CAD drawings to the community, encouraging all to modify and improve upon them. For more information, visit our GitHub or wiki. We're eager to see the innovative adaptations you come up with. Join our Discord community to share your unique remakes, or to engage in discussions about future products.

MTR-1 Back Male USB-C Adapter: Some wall plugs and receptacles with smart charging do not work

Style:

Use the LD2450 mmWave to instantly detect when someone walks into the room and turn on the lights. The MTR-1 also has multi target and multi zone. You will not only know when someone comes into the room, you'll know where they are.

The mmWave location function allows you to know if someone is at the stove, sink, or refrigerator in your kitchen. Is someone on the couch, or sitting in the chair? 

The mmWave can also be placed under your bed to determine if someone is in the bed or not. This can make for great morning or alarm automations.The RGB led is great for notifications. Trash night? Turn the LED green. Mail in the mailbox? Turn the LED blue.

The piezo buzzer is great for notifications you don't want to miss (also good for party tricks playing songs). Has your CO2 level risen to very high levels? Beep the sensor to let you know to open a window. Did your front door just open? Beep once as a notification.

Use the UV sensor to let you know how much sun is coming through the window. Or use the LUX sensor to only turn on the lights if it is dark in the room.

The optional CO2 sensor is very eye opening. Many people do not know the air in their office or bedroom reaches CO2 levels that have an affect on you. From poor sleep at night, drowsiness in the office, and brain fog can all be caused by high CO2. This sensor will let you know if your levels are getting too high and you need to turn on the air circulation or open a window.

Product Details

Details

mmWave Radar Sensor (HLK-ld2450)

Max Distance: 6m (19.6 ft)

Max Number Of Targets: 3

Number of Zones: 3

LUX and UV Sensor (LTR-390UV)

Temperature / Pressure Sensor (DPS310)

Provides accurate readings of temperature and pressure. The pressure enhances the readings from the CO2 sensor. Note: The ESP32-C3 in constant WiFi connection generates significant heat; you might need to adjust the offset based on your setup and the temperature won't be as good as a dedicated sensor with less heat build up.

C02 Sensor (Optional SCD-40)

This optional add-on brings a CO2 sensor to the package, which comes pre-calibrated and ready to use. (This device does not meet the requirements for CO2 safety monitoring per the NBIC, NFPA, or IFC)

Bluetooth Tracker(ESP32-C3-Mini) - YAML Config Required

Track Bluetooth devices in your house, letting you know which devices are closest to the sensor. You will need to know the MAC of the Bluetooth devices you want to track.

Find your phone if you left it in the office or the bedroom.

Know who just walked into the room.

Track a beacon attached to your dog's collar.

RGB Pixel

RGB neopixel

Piezo Buzzer

Emits different beep patterns based on various alerts.

Great first sensor

I love the possibilities this sensor opened up for automations. There's a lot packed into this small sensor!

Pretty good

Would be even better if it had some better mounting options.(screw holes) Especially since the radar sensor is ultra sensitive for motion, including the motion of the sensor (relative to the surroundings)
I have not adopted the device into ESP-home (as I don't quite get the benefits, and if i will be able to go back)
I do not like the way the temperature and humidity sensor callibration is implemented (I needed an 18 degree temperature offset for the SCD40, and a 24 degree offset for the DPS310.. what ??)
- the bluetooth toggle does not work. bluetooth is always on
- the motion time-out feature does not work
- the startup light blink does not work

Hi Oscar,

Thanks for your feedback, we really appreciate it! We will definitely look into mounting options. Our 3D files are open source, so feel free to remix them or suggest new designs.

The temperature and humidity offset you're seeing is due to heat generated by the ESP affecting the sensor accuracy. The Bluetooth toggle should work, as it's used for connecting to the HLK Radar Tool app for mmWave control.

Could you provide more details about the motion timeout issue? Also, the startup light blink was removed previously, but we have not fully updated the code yet. We will work on addressing this.

Thanks again, and please reach out if you have more suggestions or questions.

Best,

I love it, but the case and male USB plug need to be stronger

Great price, I'm mainly using it for CO2 monitoring. Automation with HA when PPM is > 1000, sends us a notification and turns the LED red on the device which is very useful to not have to look at your phone.

But if someone plugs something into the outlet next to it the internal components come loose and i have to re adjust. Using the mezzanine to male USB to wall wort transformer
