The LD2450 is a 24 GHz FMCW mmWave radar module for presence, distance measurement, and position tracking. Compared to a simple presence module like the LD2412, the LD2450 not only detects presence but also the direction, position, and movement of people in a space. Suitable as an upgrade for CeilSense and as a replacement or expansion module for the UltimateSensor series.
Features
-
Presence + tracking
Detects people and motion with real-time distance and position data.
-
24 GHz FMCW radar
Operates in the 24 – 24.25 GHz band with accurate short-range radar tracking.
-
Detection range
Up to approximately 8 meters, with an angular range of about ±60° horizontal and ±35° vertical.
-
UART interface
Serial communication via 4-pin connector, suitable for ESP32, ESPHome, Raspberry Pi, and other microcontrollers.
-
Compact size
Small module of approximately 15 × 40 mm, easy to integrate into existing enclosures and designs.
-
5V power supply
Low consumption and easy to control from existing sensor or embedded setups.
Applications
-
CeilSense upgrade
Replace the standard LD2412 and add position tracking.
-
UltimateSensor module
Use the LD2450 as a replacement or expansion module within compatible UltimateSensor V1 and V2 setups.
-
IoT and automation
Suitable for presence detection, zone monitoring, motion analysis, and smart automations.
Please note: if you use the LD2450 instead of an LD2412 in the CeilSense, the detection behavior will also change:
- You will move from simple presence detection to tracking of people/positions.
- The module will become noticeably warmer during use; keep this in mind with nearby temperature sensors.
- The effective detection area is narrower than with an LD2412, especially with ceiling mounting.
