MTR-1 Multi-Target Radar Multisensor For Home Assistant (LD2450)
MTR-1 Multi-Target Radar Multisensor For Home Assistant (LD2450)
Description
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.
Use Cases
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.
Details
mmWave Radar Sensor (HLK-ld2450)
- Max Distance: 6m (19.6 ft)
- Max Number Of Targets: 3
- Number of Zones: 4
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.

I use this sensor primarily to monitor for movement in certain areas during certain time intervals and monitor lights to ensure I have shut them off after an hour, otherwise send a notification. This unit is slightly larger than the MSR-2, but I do like the stand as all that is needed for this unit is to put something heavy on the USB-C cable and it stays upright without anything else needed. It took me 5-6+ hours to determine which accessories would fit right for my use case, in the end it all worked out.
Works Great
MTR-1 Multi-Target Radar Multisensor For Home Assistant (LD2450)
Easily concealed and simple to integrate with HomeAssistant via ESPHome. I'm using the zones and position tracking to create a "spotlight" effect with individually controlled can lights in my living room.
Easy to configure with the radar tools and to get into Home Assistant
