We're excited to introduce the Apollo MSR-2 sensor, an updated version of our popular MSR-1, developed with your feedback. The MSR-2 builds on the foundation of the MSR-1, incorporating several incremental upgrades to enhance performance and usability.

What's New?

  • Compact Design: The MSR-2 has a smaller form factor, making it easier to integrate into your projects and living spaces without sacrificing functionality.
  • Additional Expansion Slot: We've added a back expansion slot, allowing new accessories like a rear-facing female USB port for clean installations.
  • Updated Sensors: We've upgraded to the DPS310 for improved pressure and temperature accuracy. The base MSR-2 includes only pressure and temperature readings from the DPS310. However, humidity sensing can still be added through the optional CO2 sensor module.

For MSR-1 Users: The MSR-2 is an incremental update designed with your feedback in mind, rather than a major upgrade. Both sensors will continue to be supported, with updates provided as part of our commitment to all users.

MSR-2 mmWave Tuning Videos

CO2:

Use the mmWave to instantly detect when someone walks into the room and turn on the lights. Since mmWave is so good at still detection (detecting you sitting very still), you can also keep the lights on while you are in the room.

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, drowsyness 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

mmWave Radar Sensor (HLK-ld2410b)

  • 1 Target tracking
  • Very good still detection
  • Very good tuning capability
  • Ability to tune out false positives

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/humidity won't be as good as a dedicated sensor with less heat build up.

C02 Sensor (Optional SCD-40)

  • True CO2 sensing

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

Feature packed, hard to tune

I bought these because when looking for presence sensors, these kept coming up. In short: seems like they’d be great if I could dial in the settings. They’re not very intuitive. Until then, I’ll keep having lights go on and off randomly (instead of auto off/on when I’m in/leave an area) via my automations. A simpler gui would make this product perfect. As is now, gotta find time to really tune it if you want it to work as desired.

Cool Sensor, but several shortcomings

I bought gpio header hoping I could hook up a IR diode, but it doesn't work out of the box due to the RGB LED. Also I bought a swivel mount, and its not compatible with the GPIO header, dang. Finally, its not well calibrated out the box, so I haven't had a chance to fully dig in and set it up.

MSR-2 Presense sensor.

I was looking for an unobtrusive mmwave presence sensor. My primary target was a bathroom, but I trialed it in my office. I would have preferred Zigbee or Zwave as opposed to Wifi, but the ESPHome platform is completely reliable for me so far. I put minimal time in to restrict detection when people walk by in the hall. There' a lot more to this unit than I'm using, but it's 100% reliable detecting me at my desk and keeping the lights on and turning them off automatically.

Easy to Use and Integrate

This was something I waited too long to purchase. I loved how simple it was to open the box, plug it in, and integrate right into home assistant.

Fantastic Little Sensor!

I've really loved the MSR-2. I've had it going for about two weeks now and it really is a powerful little sensor with lots of cool features. I've been using it primarily for on and off light automations and it has been top notch. Tuning the radar was pretty easy, and it does great picking up motion and stillness. I've got some unique use case challenges with cats and the senor pointed directly at a large couch - but even with those issues it's still working wonderfully. I would highly recommend and I will definitely be purchasing more for other areas in the house.
