ZGB CB3S Smart Human Presence Sensor

ZGB CB3S Smart Human Presence Sensor (Model: longCuiz-1)

Upgrade your automated ecosystem with the ZGB CB3S Human Presence Sensor (longCuiz-1). Powered by highly precise 24GHz millimetre-wave (mmWave) radar technology, this sensor completely outperforms traditional PIR motion detectors. Instead of only registering active movement, it tracks static presence—detecting micro-motions down to breathing and heartbeats.

At its core, the device leverages the reliable Tuya CB3S module built on the high-performance Beken BK7231N platform. This grants seamless, ultra-stable dual-mode 2.4GHz Wi-Fi and Bluetooth LE provisioning, making it a versatile drop-in solution for advanced smart home enthusiasts and automation professionals.

⚡ Key Features for Your Smart Home

• True Presence Sensing (mmWave): Utilises a 24GHz radar frequency to detect people who are completely still, sitting, or sleeping. No more lights turning off unexpectedly while reading or working.
• Highly Extensible Architecture: Features the standard Tuya CB3S chip. Advanced DIY makers can explore OpenBeken firmware paths or local integrations via custom scripting.
• Comprehensive Customisation: Adjust presence distance, detection bounds, and sensitivity settings (1–3 levels) via supported IoT application protocols.
• Instant Scene Linkage: Seamlessly pairs with automated smart plugs, lighting arrays, and home security rules.
• Battery Powered: No wires and a long battery life using 2 x Standard AAA batteries.

💡 Ideal Applications

Energy-Saving Lighting Control

Install in kitchens, offices, or bathrooms. The device keeps lights on while you’re in the room and cuts energy costs by shutting arrays down the moment you step away.

Advanced Whole-Home Security

Identify real intruders over environmental shifts. Because it relies on non-ionising microwave radar, it easily operates as a safe, unblinking 24/7 boundary monitor for residential or commercial properties.
