Frequently Asked Questions
The Sensirion SHT4x is one of the most accurate temperature and humidity sensors available, used in medical devices and scientific instruments. It delivers ±0.1°C temperature accuracy and ±1.8% humidity accuracy—significantly better than many competing sensors on the market.
Dew point is the temperature at which moisture condenses from the air. Monitoring dew point helps prevent condensation damage in storage areas, data centers, museums, basements, and any environment where moisture control matters. The sensor calculates dew point automatically from temperature and humidity.
Both use the same Sensirion sensor technology with ±0.1°C accuracy. The 3-in-1 adds humidity and dew point measurements while storing 8,000 readings (vs 20,000 for temperature-only). Choose the 3-in-1 if humidity matters for your application; choose temperature-only for maximum data storage.
The CR2032 battery typically lasts up to 1 year with a 15-minute logging interval. Yes, the battery is user-replaceable—twist the back cover to access the compartment and replace with a standard CR2032 coin cell.
Common uses include home comfort monitoring, wine cellar and cigar humidor management, greenhouse and indoor garden environments, musical instrument storage, HVAC verification, pharmaceutical storage, server rooms, and food storage areas where humidity affects product quality.
The bmLogger app displays temperature and humidity graphs over time, letting you spot patterns and correlations. Export data as CSV for detailed analysis in spreadsheet software, or use the BM Gateway with bmCloud for long-term trend analysis and automated reporting.
Yes, the Disc Mini 3-in-1 is fully compatible with the BM Gateway. Connect to bmCloud for 24/7 remote monitoring of temperature, humidity, and dew point from anywhere, with email alerts when conditions exceed your thresholds.
