SenseGuard Presence Core 24GHz- Zigbee
Human Presence Sensor
24GHz Radar Precisely Detects Even the Slightest Breath
The presence sensor continuously emits radar waves to detect human presence. The 24GHz radar is more accurate than 5.8GHz, effectively capturing subtle human movements such as chest expansion during breathing in daily activities, reducing missed detections and false alarms.
*Note: Cannot reliably detect a sleeping person due to extremely subtle chest movements caused by breathing during sleep.

Stationary State: Within 3 meters facing the device.
Self-learns Interference. Only Detects What Matters.
When Detection Calibration is enabled, the device autonomously learns the motion patterns of interfering objects in the detection area and filters them out. This precisely eliminates false triggers from common household sources like appliances and water pipes, greatly improving detection accuracy and providing a more convenient experience.

FAQ
1. Detection capability
The SNZB-06P24 accurately detects subtle human movements (chest expansion during breathing, small limb motions like hands). For a completely still person, detection works best within 3 meters directly facing the device. The device cannot accurately detect a sleeping person.
2. Anti‑interference capability
The device’s anti‑interference capability comes from the precision of the 24GHz mmWave radar and the Detection Calibration feature. Detection Calibration accurately filters out fixed‑position interference sources in the detection area, such as appliances, water pipes, and large metal surfaces. If an interference source changes position, Detection Calibration must be rerun.
The SNZB-06P24 cannot directly filter pet interference — you can avoid pet activity areas by adjusting the sensor upward.
3. Brightness accuracy
Different sensor orientations may cause inconsistent brightness readings. Please fix the sensor orientation and use the calibration function to adjust the brightness.
4. What is eWeLink BLE Setup and how do I use it?
Third‑party ecosystem users can connect to the eWeLink app via Bluetooth to configure advanced settings. The configuration is saved locally on the device and can be adjusted anytime through eWeLink BLE Setup.
Scan the QR code on the product with the eWeLink app, select eWeLink BLE Setup, and follow the on‑screen steps to add the device.
5. Can’t add the device via eWeLink BLE Setup?
Press and hold the reset button for 10 seconds to reset the device. Note: This will clear all Zigbee pairing information from the device.
6. The SNZB-06P24 cannot maintain a Bluetooth connection?
First, exit the Zigbee pairing mode on the device. Then enter the device details page in the app to keep the connection active. When the device is in Bluetooth connection mode, the blue indicator light stays on.
