Inkbird WiFi Temperature & Humidity Sensor IBS-TH3 — Compact remote monitoring, 1-year data

The Inkbird IBS-TH3 is a compact WiFi temperature and humidity sensor that delivers remote real-time monitoring, configurable alerts, and up to one year of stored environmental data.

Small enough to tuck into tight spaces, the IBS-TH3 combines a thermometer and hygrometer in one pocket-sized device. It connects to your home Wi‑Fi so you can view live readings and historical trends from the Inkbird app. Built for homes, greenhouses, fridges, cigar cabinets and similar enclosed areas, it provides accurate environmental tracking without complicated setup.

How accurate and reliable are the readings?

The IBS-TH3 offers laboratory-grade precision for everyday monitoring: temperature accuracy is approximately ±0.3°C (±0.5°F) and humidity accuracy is about ±3% RH. Readings are sampled at configurable intervals and recorded so you can review changes over time and export data if needed.

• Temperature range: -20°C to 60°C (-4°F to 140°F)
• Humidity range: 0% to 99% RH
• Typical accuracy: ±0.3°C / ±0.5°F and ±3% RH
• Adjustable sampling intervals to balance resolution and battery life

What alerts and remote features does the device provide?

Set custom high and low thresholds for both temperature and humidity to get instant notifications on your phone whenever conditions fall outside your preferred window. Alerts arrive through the Inkbird app over Wi‑Fi, so you receive updates even when you’re away from home.

• Push notifications for threshold breaches
• Remote live view via the Inkbird app from anywhere with internet
• Configurable alarm limits for temperature and humidity separately
• Ability to export historical logs for analysis

Where can I place the sensor and how portable is it?

The IBS-TH3’s compact profile lets it fit into confined spaces where larger sensors won’t, like cigar humidors, guitar cases, small greenhouses, refrigerators, or terrariums. Its lightweight design makes repositioning simple when you need to compare different zones.

• Pocket-sized housing suitable for small enclosures
• Works well in glass containers, cabinets, and instrument cases
• Easy to move between locations for comparative checks
• Battery-powered operation with settings to extend life

How does data storage and export work?

The sensor stores recorded measurements and presents them as historical graphs in the Inkbird app. You can select recording intervals to extend battery life or increase detail, and export stored logs for offline review or documentation.

• On-device recording preserved up to one year depending on interval
• Graphical history view inside the app for trend analysis
• Exportable data files for further investigation or record keeping
• Longer intervals maximize battery life; shorter intervals increase detail

Who is this for? The Inkbird IBS-TH3 is designed for homeowners, hobbyists, and small-space cultivators who need dependable, remote environmental monitoring without professional installation. It’s ideal for anyone protecting temperature- or humidity-sensitive items—like musical instruments, cigars, seedlings, food storage, or indoor plants—who wants simple Wi‑Fi access, configurable alerts, and the ability to review historical conditions.
