Overview
The HOBO MX2203 TidbiT Water Temperature Logger is a professional device that uses Bluetooth Low Energy (BLE) technology to transmit High Accuracy Temperature Measured value directly to iOS or Android mobile devices. Designed for durability, it features a rugged waterproof construction for long-term deployment in underwater environments such as streams, lakes and oceans, with a maximum water resistance of 120 meters (400 feet).
Features
1. Convenient wireless setup and download via Bluetooth Low Energy (BLE).
2. Large memory stores 98,000 measurements.
3. Waterproof to 120 meters (400 feet).
4. Users can replace the battery.
5. Waterproof startup protects the logger during deployment.
6. When the temperature exceeds the set threshold, the LED alarm notifies you.
7. Battery life is saved by water detection.
8. Works with Onset's free HOBOmobile app.
9. +/- 0.2 ℃( +/- 0.36 ° F) accuracy.
Principle
The logger performs temperature measurements with a built-in Sensor and wirelessly transmits measurement data to mobile devices using Bluetooth Low Energy (BLE) technology. Its water detection function identifies whether it is underwater by monitoring the water conductivity of the environment to optimize power management. Data storage is in the device's internal memory and can be set up, downloaded and analyzed via a companion app.
Applications
Indoor environment monitoring, outdoor environment monitoring, underwater environment monitoring (streams, lakes, oceans)
Standards
Bluetooth Smart (Bluetooth Low Energy, Bluetooth 4.0)
Steps
1. Connect the device via Bluetooth using the matching HOBOmobile app.
2. Program setting parameters such as Sampling interval and Alarm threshold.
3. Deploy the recorder to the target monitoring environment (indoor, outdoor or underwater).
4. The recorder automatically performs temperature measurement and Data storage according to the settings.
5. Download the stored data wirelessly through the app for analysis.
Notice
* The recorder operates in indoor, outdoor and underwater environments.
* Support temperature and water temperature measurement.
The temperature measurement range is -20 to 70 degrees Celsius.
* Temperature accuracy is +/- 0.25 ° C (-20~ 0 ° C) or +/- 0.2 ° C (0~ 70 ° C).
* Water detection is effective at water conductivity ≥ 100 µS/cm; deionized water or water conductivity below 100 µS/cm may not be detectable.
* When the water temperature around the Electrode is below 0 ° C (32 ° F) and freezes, the conductivity circuit may not reliably detect the water.
* Recorder with polypropylene (PP) housing, EPDM sealing ring, stainless steel screws and Santoprene ® (TPE) protective material.
* The battery is a CR2477 3V lithium battery, which can be replaced by the user. The typical Battery life is 3 to 5 years.
