Moisture recorder and soil temperature MX2307

THE'recorder moisture and temperature of the ground HOBO MX2307 is fully integrated, it is a solution to low cost and with wireless data unloading Bluetooth. 
It measures both the'humidity and soil temperature and exists in another version which measures only l'humidity soil (HOBO MX2306).

The recorder is the ideal solution for researchers and producers looking for accurate data they need to save water and to improve the yields reduce harmful runoff and protect ecosystems.
With just one phone mobile, one tablet or a Windows laptop running the free application HOBOconnect of'Onset , users benefit from a configuration wireless and download data via Bluetooth when located within 100 feet of the recorder, which facilitates data recovery from hard-to-reach terrain locations.
For indoor spaces, such as greenhouses, users can add the mX gateway for remote access to data in the software HOBOlink based on cloud of'Onset.   

Technical specifications:

- Ready to deploy, with pre-attached sensors
- Easy configuration and data unloading with the free HOBOconnect app
- Terras 10 durable soil moisture sensor lasts more than 10 years in the field
- For use in mineral soils and soilless environments
- Sturdy and pointed stainless steel tips for easy installation and better contact with the floor
- Option to display data as a percentage of field capacity

Humidity sensor functionality:

- Soil humidity: volumetric water content (VWC)
- Measurement range*:
0.00 to 0.64 m3/m3 in mineral soils
0.00 to 0.70 m3/m3 above ground
- Accuracy:
±0.031 m3/m3 typical in mineral soils with typical EC ±0.051 m3/m3 solution in soilless medium
- Resolution: 0.001 m3/m3
- 70 MHz dielectric measurement frequency

* Sensor data may be post-calibrated if necessary (e.g. sensor is used in non-mineral soil types or higher accuracy than standard is required). Users can apply a calibration equation to data exported from the application. The VWC range will depend on the calibration equation.

Temperature sensor functionality:

- Range: -40 to 100°C (-40 to 212°F), with immersion of tip and cable in fresh water up to 50°C (122°F) for one year
- Accuracy:
±0.25°C from -40 to 0°C (±0.45 from -40 to 32°F)
±0.2°C from 0 to 70°C (±0.36 from 32 to 158°F)
±0.25°C from 70 to 100°C (±0.45 from 158 to 212°F)
- Resolution: 0.04°C (0.072°F)
- Drive: - Response time:
3 minutes in the air moving at 1 m/s
20 seconds in agitated water
4 minutes in the air moving at 1 m/s with the solar radiation shield RS3-B

Recorder functionality:

- Operating range: -25° to 60°C (-13° to 140°F)
- Radio power: 1mW (0dBm)
- Transmission range: sight line of approximately 30.5 m (100 feet)
- Wireless data standard: Bluetooth low consumption (Smart Bluetooth)
- Log rate: 1 second at 6 p.m
- Modes of logging: fixed interval (normal, statistical) or gust
- Memory modes: wrap when full or stop when full
- Start modes: immediate, push button, date and time or next interval
- Stop modes: when the memory is full, press the button, date and time or after a specified recording period
- Accuracy of the time: ±1 minute per month 0° to 50°C (32° to 122°F)
- Battery type: 2/3 AA 3.6 volts lithium, replaceable by user
- Battery life:
2 years, typical with 1 minute recording interval and Bluetooth Always Turn on
5 years, typical with 1 minute recording interval and Bluetooth Always Off
Faster recording intervals and statistical sampling intervals, gust recording, staying connected to the application, excessive downloads and pagination can have an impact on battery life.
