Aggregated specification data for the SwitchBot Contact Sensor identifies a Nordic Semiconductor nRF52 series SoC, supporting a Bluetooth 5.0 LE stack. Technical specifications reveal an integrated ambient light sensor, providing secondary logic variables for automation. Performance metrics indicate a local trigger latency of under 200ms when paired directly with SwitchBot ecosystem peripherals.
Material analysis confirms a power system utilizing AAA batteries, with a service life estimated at 2 years under low-traffic conditions. For wide-area network notifications and integration with Alexa or Google Home, a SwitchBot Hub is mandatory. The device supports local Bluetooth mesh routing when within 30 feet of a compatible gateway or mains-powered SwitchBot plug.
Technical throughput for cloud-based alerts is influenced by the polling rate of the required hub, which may differ from local trigger speeds.
The unit includes a motion sensing component, allowing for multi-variable state detection within a single chassis. The physical profile is larger than Zigbee-only competitors due to the multi-sensor array and AAA battery housing.
The SwitchBot Wireless Door Alarm Sensor serves as a feature-rich alternative for users who require integrated light and motion sensing in addition to contact detection.
This multi-sensor hardware is indexed within the contact sensors category for its specialized BLE mesh capabilities.
