Technical specifications for the SwitchBot Motion Sensor indicate a dual-detection architecture utilizing a passive infrared (PIR) pyroelectric sensor for kinetic movement and an integrated photodiode for illuminance monitoring. Aggregated data confirms a horizontal field of view of 110 degrees with an operational detection radius extending to 9 meters. The chassis is constructed from ABS polymer and incorporates a magnetic mounting system providing 360-degree rotational adjustment for precise directional alignment.
Communication protocols rely on Bluetooth Low Energy (BLE), which mandates the use of a signal bridge or local proxy to facilitate integration with high-level automation platforms such as Alexa or Google Home. Material analysis of the power system lists a dual AAA battery configuration with a projected service life of 12 to 18 months, depending on trigger frequency. Performance metrics demonstrate that while the integrated light sensor enables complex logic gating for environmental lighting, the software-defined cooldown period introduces a fixed latency between successive detection events.
Functional Operational Modes
- Dual-Trigger Logic: Synchronizes motion detection with ambient lux levels for environmental lighting control.
- Local Execution: Supports direct-to-hub communication to minimize cloud-dependent latency.
- Proximity Detection: Utilizes Bluetooth signal strength to estimate occupant distance for localized triggers.
Structural analysis confirms that the device footprint is optimized for non-invasive installation via adhesive or magnetic interfaces. While the hardware is compatible with third-party software environments through Bluetooth proxies, the primary firmware is tuned for the SwitchBot proprietary ecosystem.
For installations requiring a more resilient communication protocol, the Aqara Zigbee Motion Sensor offers a 1-second reset interval and utilizes the Zigbee 3.0 mesh standard to reduce signal interference.
This unit is classified within the broader ecosystem of motion and presence sensors, serving as a primary input node for automated environmental control systems.
