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

As described and more

Hardware is amazing, does exactly what is specified on the box. Integrates with HA with no fuss at all - works for occupancy, and motion across a rather large room with the ability to detect at several distances - imagine kitchen and dining room as separate triggerable (and configurable distance) locations from a single sensor.
Not totally plussed with the 3d printed ball mount solution, but it's an innovative idea AND they give away the 3d print files, so complaints on something like this are minimal.
Only had it in my hands for 2 weeks so the amount of playing around is limited, but I feel to be just scratching the surface of what this tiny sensor can accomplish.

Awesome small presence sensor (almost perfect - almost)

I really like the Apollo MSR-2. I created a 3D model for a ceiling mount and am gradually replacing all my presence sensors at home. A reliable presence sensor is an instrumental part of my smart home.

The only thing that’s really missing is a user-friendly zone configurator—something similar to the Presence One Lite from Lewis, who created a very helpful add-on for his devices.

Outshines all the others

I’ve tried a bunch of different mmWave sensors, and so far, the MSR-2 puts them to shame. The MSR-2 is a bit more raw, and will take a little bit more time and effort to tune, but it gives you access to *all* of the variables you need to tune it exactly how you want. And once you’ve got it set up, it’s rock solid.
For future versions, it would be great to see an improvement in form fact. For example, the outlet mount is convenient, but it sits slightly off center and you can tell the case is 3D printed. But honestly the device itself is tiny compared to a lot of other mmWave sensors, so even if it’s a little rough around the edges, it’s pretty easy to hide.
For the money, I don’t think there’s a better presence sensor option on the market. My strategy has been to buy a bunch of these and scatter them throughout the big rooms instead of trying to find one perfect sensor to tackle big spaces, and I don’t regret it for a second.
Overall I'm a huge fan of this little sensor and I'll be ordering a few more of them, shortly!
