RA24D18 24GHz Presence Sensor Module – Bluetooth Version 5.0, Human Detection & Occupancy Monitoring

📝 Product Description

The RA24D18 24GHz radar module (Bluetooth version) is a smart presence detection sensor that combines mmWave radar technology with Bluetooth connectivity. It is designed to detect human presence, motion, and even small movements like breathing, making it much more accurate than traditional PIR sensors.

With its built-in Bluetooth module, the RA24D18 allows wireless configuration and data transmission, which makes it easier to integrate into IoT applications, smart lighting, home automation, and occupancy monitoring systems.

The sensor can reliably detect through materials like glass, wood, and plastic, and is unaffected by lighting conditions, temperature changes, or weather interference. Its compact size and low power consumption make it a great choice for energy-saving solutions and smart environments.
