The Apollo Automation R PRO-1 PoE mmWave Multisensor (LD2450 and Optional LD2412) is our most advanced presence sensor to date. Designed for power, precision, and reliability, the R PRO-1 is a compact PoE mmWave sensor built for high-accuracy motion detection and environmental monitoring in smart homes and commercial buildings. The base sensor comes with the LD2450, with the option to add on the LD2412.

This versatile sensor also supports USB-C power and offers built-in Wi-Fi and Bluetooth connectivity, allowing for flexible installation and seamless smart home integration. Its small form factor combined with PoE or USB-C power options makes the R PRO-1 ideal for quick, space-efficient deployment in any environment.

Equipped with optional support for the SCD40 (true NDIR CO₂, temperature, and humidity), the R PRO-1 transforms into a powerful all-in-one indoor environmental monitor.

Like all Apollo products, the R PRO-1 is fully local, open-source, and requires no cloud subscription. It integrates seamlessly with Home Assistant and Homey, making it a top-tier solution for anyone seeking a local-first, privacy-focused motion and environmental sensor.

CO2, Temperature, and Humidity:

Use mmWave radar to instantly detect motion and automatically turn on the lights when someone enters a room. Thanks to its excellent ability to detect stillness, mmWave also keeps the lights on while someone is seated or resting. This is ideal for offices, bedrooms, and living areas.

Place the mmWave sensor under a bed to detect presence during sleep, enabling powerful morning and sleep automations.

The built-in RGB LED is perfect for visual alerts. Turn it green for trash night or blue when mail arrives in the mailbox.

The onboard piezo buzzer provides clear sound notifications. Use it to beep when CO₂ levels are high, when the front door opens, or for fun effects like sound alerts and party tricks.

The UV sensor lets you monitor sunlight coming through windows, while the LUX sensor allows smart lighting automations that only activate when the room is dark.

An optional NDIR CO₂ sensor gives real-time air quality data. Many people do not realize how high CO₂ levels can get in bedrooms or offices. Elevated levels can cause drowsiness, brain fog, and poor sleep. The sensor alerts you when ventilation is needed, helping you maintain a healthier environment.

Apollo’s mmWave smart home sensors combine advanced presence detection and environmental monitoring to create responsive, intelligent, and comfortable living spaces.

Product Details

Dual mmWave Compatibility: LD2412 and LD2450

The R PRO-1 supports both the LD2412 and LD2450 mmWave radar modules:

• LD2412 (Optional) delivers high-accuracy still presence detection, ideal for seated or sleeping individuals.

• LD2450 enables multi-zone motion tracking, allowing you to identify precise movement and location across zones.

You can combine both modules to create a hybrid smart presence sensor capable of advanced occupancy detection in real time.

Smart Environmental Sensing Features

In addition to presence tracking, the R PRO-1 also functions as a robust environmental monitoring sensor, including:

• LTR390 for ambient lux and UV sensing

• Two addressable RGB LEDs for visual notifications and automation feedback

• Piezo buzzer for audio alerts

• Bluetooth support for tracking and Improv Wi-Fi provisioning

Optional Mezzanine Expansion Board:

• SCD40 for high-accuracy NDIR CO₂ sensing with built-in temperature and humidity monitoring

Together, these components make the R Pro-1 a feature-rich air quality and environmental sensor suitable for automation, air monitoring, and energy-efficient control.

Modular and Customizable

• Rear mezzanine port for modular add-ons

• Optional GPIO header for connecting custom sensors and peripherals

Compact, Flexible Installation

With a size of approximately 57x45mm, the R PRO-1 is designed for easy and versatile installation:

• Mount on a flat surface

• Fit into a standard single gang box

• Install in a compact EU back box

• Ceiling mount as needed for discreet motion and presence detection
