2. Product Features

Smart App Control: Monitor temperature and humidity data in real-time via Bluetooth connection using the dedicated smart application. The measurable temperature range is -20°C to 65°C (-4°F to 150°F), and the humidity range is 0% RH to 99% RH.
Fast & High Precision: Equipped with a high-quality sensor, the device offers a temperature accuracy of ±0.5°C/±1°F and humidity accuracy of ±5% RH. Data updates occur once per second for enhanced precision. The system supports sharing sensor data with family members and allows a single mobile phone to manage multiple wireless temperature sensors.
Mini & Portable Design: The wireless Bluetooth thermometer features a compact design, optimizing space and convenience. It includes a lanyard for easy attachment to various objects. The device also has a magnetic backing, and an adhesive magnetic sheet is provided for placement on non-magnetic surfaces.

3. Setup

Unboxing: Carefully remove the sensor(s) and any accessories (lanyard, adhesive magnetic sheets) from the packaging.
Battery Installation: Each sensor requires one AAA battery (not included). Open the battery compartment on the back of the device and insert the battery, ensuring correct polarity.
App Download: Download the 'Sensor Blue' application from your smartphone's app store (available for iOS and Android).
Pairing:
- Ensure Bluetooth is enabled on your smartphone.
- Open the 'Sensor Blue' application.
- If the app does not automatically detect the sensors, press and hold the central button on the sensor until a red LED flashes. The app should then discover the device for pairing.
Placement: Position the sensor in your desired location. You can use the integrated magnet to attach it to metallic surfaces, or use the provided adhesive magnetic sheets for non-magnetic surfaces. Alternatively, use the lanyard to hang the sensor.

4. Operating Instructions

4.1 Real-time Monitoring

Once paired, the 'Sensor Blue' app will display real-time temperature and humidity readings from your sensor(s). The data refreshes approximately once per second.

4.2 Data Logging and Export

The app allows for professional data recording and analysis:

Recording Intervals: Customize data logging intervals from 0 to 60 minutes.
Recording Duration: Select a recording duration of up to 600 days.
Data Export: Export historical records in batches as CSV files for further analysis.

Note: After setting the recording parameters, you must manually click 'Start' within the app for data logging to begin.

5. Maintenance

Battery Replacement: When the battery level is low, replace the AAA battery in the sensor. Ensure the device is powered off before opening the battery compartment.
Cleaning: Use a soft, dry cloth to clean the exterior of the sensor. Do not use liquid cleaners or abrasive materials.
Storage: Store the sensor in a cool, dry place when not in use for extended periods. Remove the battery if storing for several months.
Water Resistance: The product is NOT waterproof. Do not place the Bluetooth thermometer in a refrigerator or a container filled with water, as this will damage the device.

6. Troubleshooting

Connection Issues: The effective Bluetooth range is approximately 50 meters in open environments. Physical obstacles (walls, furniture) can significantly reduce this distance or prevent a connection. Ensure your smartphone is within range and there are no major obstructions.
Data Not Recording: After configuring recording settings in the app, you must explicitly click the 'Start' button to initiate data logging. The sensor has a limited data storage capacity. Once full, it retains recorded data until you transfer it to your phone and manually start a new recording session.
App Disconnection: To conserve battery life, the app may enter a background operating mode when your phone screen is off, locked, or when other applications are in use, leading to a temporary disconnection from the thermo-hygrometer. Reconnecting typically takes a few seconds when you reopen the app.
Inaccurate Readings: If you suspect inaccurate readings, use the calibration feature within the 'Sensor Blue' app to reconfigure the sensor for more precise measurements.
