Zigbee Temperature and Humidity Sensor for Indoor Climate Monitoring
Monitor temperature, humidity, dew point and vapour pressure deficit from one compact indoor sensor. The AirGuard TH Lite SNZB-02B is designed for rooms and small enclosed spaces where changing conditions can affect comfort, stored items or plants.
A compatible Zigbee gateway is required for app access, history, alerts and smart-home functions.
Key Benefits
Detailed environmental readings
See temperature and relative humidity together with calculated dew point and VPD data.
Fast updates
Readings refresh every five seconds to show changes in indoor conditions.
Compact placement
The narrow body can be attached with adhesive or suspended by its hanging loop.
App history and alerts
Review up to six months of recorded trends and receive notifications when selected limits are exceeded.
Main Features
High-accuracy sensing
Stated accuracy is ±0.2°C / ±0.4°F for temperature and ±2% RH for humidity.
Dew point monitoring
Helps identify conditions in which condensation may develop on walls, furniture or stored possessions.
VPD monitoring
Provides an additional measurement for assessing the air conditions around indoor plants.
Smart scenes
The sensor can trigger compatible equipment, such as a fan or dehumidifier, through a suitable Zigbee gateway and smart-home setup.
Voice and ecosystem support
Voice queries depend on the connected gateway and platform. Apple Home integration requires a compatible Matter Bridge.

Bedrooms, living areas and home offices
Indoor plant growing areas
Guitar cases, cigar humidors and jewellery cabinets
Wine racks and other compact indoor storage spaces
