MTR-1 Multi-Target Radar Multisensor for Home Assistant (LD2450)

Introducing the Apollo Automation 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. The MTR-1 can measure multiple targets, zones, target coordinates, RGB, buzzer, LUX/UV, and CO2 (optional variant). Powered via USB-C (cable not included) using a USB power supply, 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. Sensors & Specifications mmWave Radar Sensor Model: HLK-ld2450 Max Distance: 6m (19.6 ft) Max Number Of Targets: 3 Number of Zones: 3 LUX and UV Sensor Model: LTR-390UV Temperature / Pressure Sensor Model: 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 buildup CO2 Sensor (Optional, variant) Model: 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 Model: ESP32-C3-Mini 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 LED  Piezo Buzzer Emits different beep patterns based on various alerts. 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 (variant) 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.
