KW307 24 GHz Human Presence and Spatial Sensing Module

The KW307 is an advanced 24 GHz human presence sensor designed to detect both moving and stationary people. Unlike conventional motion sensors that may stop responding when a person remains still, the KW307 can detect subtle human micro-movements and continuously determine whether a space is occupied.

The sensor also provides real-time target location information, including distance and angle, allowing connected systems to respond more intelligently to where people are located. Its configurable sensing range, field of view and sensitivity make it suitable for smart buildings, lighting systems, HVAC control, appliances and other human-aware devices.

Key Features

• 24 GHz radar human-presence sensing
• Detects moving and stationary people
• Detection range up to 20 metres, depending on module configuration and environment
• Tracks up to four targets simultaneously
• Reports target distance and angle information
• Typical 100° field of view, configurable up to 120°
• Configurable range, sensitivity, gain and field of view
• Fast, real-time occupancy and location reporting
• Strong resistance to false triggers caused by fans, wind and vibration
• UART interface for connection to an external MCU

Typical Applications

Smart lighting, building automation, HVAC control, occupancy monitoring, energy-management systems, smart appliances, security devices, care monitoring and other human-aware IoT products.
