Precise climate monitoring

The X-Sense STH0B square sensor tracks temperature to ±0.36°C and humidity to ±2% RH while calculating dew point and VPD. It is built for gardeners, wine collectors and homeowners who need reliable indoor climate data. The device requires the SBS50 base station, which is not included.

Sustained observation

Up to 50 devices can link to a single base station with a maximum of 10 thermo-hygrometers covering up to 1700ft. The 1200mAh AAA battery supports up to one year of continuous operation and the hardware is rated for a five-year lifespan. Low-battery warnings arrive through the app before power runs out.

Quiet low-power operation

The sensor weighs 0.059 kilograms and has no moving parts, so it runs silently in any room. App alerts trigger instantly when readings leave your set range, and historical graphs let you review trends by day, month or year. Data can be exported for deeper analysis.
