Inkbird WiFi Hygrometer Thermometer 3-Pack — Greenhouse/Reptile Sensors, Swiss Accuracy, 9‑Month Battery

Inkbird's WiFi Hygrometer Thermometer 3-Pack is a compact, weatherproof temperature and humidity monitoring system with Swiss sensors, dual Bluetooth/WiFi connectivity, long battery life, and cloud plus local data storage for home and hobby use.

Whether you need steady climate readings for a greenhouse, reptile terrarium, cigar humidor, wine cellar, or multiple rooms in your house, this kit combines three wireless probes with an M2S gateway to deliver remote monitoring, alerts, and downloadable logs. The sensors sample every three seconds and use professional-grade Swiss sensing elements for accurate temperature and humidity readings, while Bluetooth 5.0 and a WiFi gateway let you view real-time data on the INKBIRD app from anywhere.

How accurate are the temperature and humidity readings?

The units rely on Swiss-made sensors that deliver fine-grained measurements; temperature accuracy is tight and humidity readings are suitable for environments that need consistent control. Readings refresh rapidly so you can detect fluctuations quickly.

• Temperature range: -40°F to 140°F with 0.36°F precision
• Humidity range: 0–99% RH with reliable repeatability
• Sampling interval: every 3 seconds for near-real-time monitoring

Can I access data remotely and keep historical logs?

Yes — use Bluetooth for local access up to about 262 ft or connect the included M2S gateway to WiFi to view data remotely on the INKBIRD app. The system stores up to 300 days of local data and keeps one year of cloud history, with export options for analysis or record-keeping.

• Dual-mode: Bluetooth 5.0 for proximity use, M2S gateway for remote access
• 300 days local storage on the device; 1 year encrypted cloud history
• Free CSV export for spreadsheets, compliance logs, or VPD tracking

How durable is the sensor for humid or outdoor spaces?

These sensors are built for damp and dusty environments, featuring an IP65 waterproof rating that resists water jets and particulate ingress. The compact housings fit tight spaces while the battery-efficient design helps them run months on a single set of batteries.

• IP65 dustproof and water-jet resistant enclosure for humid areas
• 9-month typical battery life under normal conditions
• Compact form factor fits terrariums, sheds, humidors, and greenhouses

What comes in the box and how many areas can I monitor?

The kit includes three hygrometer/thermometers and one M2S gateway so you can monitor multiple zones at once. The INKBIRD app supports multi-sensor setups and allows pairing up to 10 sensors to a single gateway for broader coverage.

• Included: 3 sensors, 1 M2S gateway, welcome guide, lifetime warranty
• Supports up to 10 sensors per gateway for multi-room or multi-tank setups
• Automatic auto-sync when connection resumes; alert push notifications

Who is this for? This kit suits hobbyists and small-scale professionals who need dependable, searchable climate records without complex hardware. Ideal users include greenhouse and indoor gardeners tracking VPD and trends, reptile owners monitoring enclosures, collectors caring for wine or cigars, and homeowners who want remote alerts for freezers, attics, or basements. The combination of Swiss sensors, dual connectivity, long-term storage, and IP65 durability makes it a practical choice for anyone who wants accurate environmental monitoring with simple app-driven controls.
