ThermoPro TP351 Bluetooth hygrometer 80m pack 📟

This compact Bluetooth hygrometer and thermometer from ThermoPro helps you monitor temperature and humidity across rooms, greenhouses or incubators with remote app access and long-term data logging. It offers the convenience of smartphone monitoring and frequent updates, making it useful for anyone who needs continuous environmental tracking at home or in a controlled space.

Key Points

The device uses an advanced NTC humidity sensor that delivers precise readings, with accuracy stated by the manufacturer at +/- 0.3 °C for temperature and +/- 2% RH for humidity. Readings refresh every 10 seconds, which helps you spot quick changes in conditions. The built-in Bluetooth connection pairs automatically with the companion app, so you can view live data on your phone without needing a base station. The set includes three sensors, allowing coverage of several locations simultaneously. For remote monitoring around larger properties, the sensors support an effective wireless range up to 80 metres according to the product information. 📱🌿

Usage Recommendations

Place one sensor at the typical breathing height in each room to get representative environmental readings. In greenhouses or incubators, position a sensor away from direct water spray or heating elements to avoid skewed results. The app allows switching between Celsius and Fahrenheit and offers alerts for thresholds, which is helpful for keeping conditions within a target band. If you need historical trends, use the export function to download stored data for further analysis. For reliable long-term use, the device requires batteries which are included, but consider keeping spare batteries on hand for uninterrupted monitoring. 📊

Positive Aspects

The ability to store and export up to two years of measurements makes this pack practical for projects that require continuous records, such as plant cultivation logs or incubator cycles. The automatic Bluetooth pairing reduces setup time, and the frequent update rate gives timely information when conditions change. Battery status is shown in the app so you can plan replacements before a sensor goes offline. One nuance to note is that the quoted wireless range and accuracies are provided by the manufacturer and real-world performance may vary with building materials or interference. 🔋
