Three-Sensor Kit with Base Station

The X-Sense STH0B31 pack delivers three square sensors and one base station for whole-home environmental monitoring. Each unit measures temperature and humidity while calculating dew point and VPD for plants, wine storage or general comfort. The system suits homeowners who want multi-room visibility without wiring. It is not suited for buyers who need leak detection or outdoor-rated sensors.

1700-Foot Wireless Range and 50-Device Limit

Sensors connect to the base station over a proprietary link covering up to 1700ft (500m) in open air. A single base station supports up to 50 linked devices, with a maximum of 10 thermo-hygrometers among them. Real-time alerts push to the app when readings leave your set range. Builders needing longer range or more than 50 nodes must add another base station.

Up to One Year on Included AAA Cells

Each sensor ships with two 1200mAh alkaline AAA batteries rated for up to one year of operation; low-battery warnings appear in the app. Historical graphs store daily, monthly and yearly trends for temperature, humidity, dew point and VPD, with export available for deeper analysis. The hardware is designed for a five-year service life. Users requiring continuous mains power or rechargeable cells will need a different solution.

Questions about this item

How many sensors can I connect to the single base station included in this 3-pack?

The base station supports up to 10 thermo-hygrometer devices and a total of 50 linked devices, so the three included sensors leave room for seven more of the same type.

What do the ±0.36 °F and ±2 % RH accuracy figures mean for daily readings?

Temperature readings stay within 0.36 °F of the true value and humidity within 2 percentage points, giving reliable data for rooms, greenhouses or wine storage.

What wireless range does the base station provide and what limits it in practice?

The system covers up to 1700 ft (500 m) in open air; walls, floors and interference will reduce the effective distance inside a typical home.
