JINK 5-in-1 Presence Sensor
Five senses. One thoughtful home.
Meet the JINK 5-in-1 Presence Sensor: mmWave radar, PIR infrared, light, temperature and humidity sensing in one compact indoor device. Bring presence and room conditions into the routines that make home feel more comfortable.
- Sense presence and motion: mmWave radar senses human presence while PIR detects movement. Use supported presence and absence states for lighting routines.
- Read the room: monitor ambient light, temperature and humidity, set light thresholds and enable environmental reporting.
- Matter-certified, connected over Thread: add the sensor using its Matter setup code. Bluetooth LE supports pairing and configuration.
- Make it fit your space: adjust radar sensitivity, presence and absence delays, and trigger settings in the Gerlsair app. Check live values, battery level and trigger history, and update firmware over Bluetooth.
- Install where it works best: CR2450 battery power, wall or ceiling mounting, adhesive or screw fixing, and an adjustable-angle base.
Before you buy: a compatible Matter controller and Thread Border Router are required. The manufacturer lists Apple Home, Google Home, Amazon Alexa, Samsung SmartThings, Aqara and Tuya. Sensor readings, triggers, routines and alerts vary by platform. Automated actions require compatible devices and configured rules. Indoor use only.
Matter: a shared language for your home
Matter is an IP-based smart home standard that helps compatible devices from different brands work together. This sensor uses Thread for its network connection and Bluetooth LE for setup. Matter supports local communication, device authentication and encrypted connections; available functions and internet requirements depend on your platform.
