Overview
Our ET107 ETo station consists of meteorological sensors, an aluminum 3 m pole, and an environmental enclosure that houses a CR1000M module and a 7 Ahr sealed rechargeable battery. The battery is recharged via an ac transformer or a 10 W solar panel. Sealed circular connectors are provided on the outside of the enclosure to simplify sensor hookup.

Detailed Description
Our ET107 ETo station consists of meteorological sensors, an aluminum 3-m pole, and an environmental enclosure that houses a CR1000M module and a 7-Ahr sealed rechargeable battery. The battery is recharged via ac power or a 10-W solar panel. Sealed circular connectors are provided on the outside of the enclosure to simplify sensor hookup.
Meteorological sensors included with the ET107 are the CS305-ET Solar Radiation Sensor, HMP60-ETS Air Temperature and Relative Humidity Probe, TE525-ET Tipping Bucket Rain Gage, and either the 034B-ETM Wind Set or WindSonic1-ETM 2-D Sonic Wind Sensor.
The ET107 can also measure the:

The ETsz() instruction requires the user to input lattitude, longitude, elevation, and crop type for a station's location in order to generate accurate calculations of ET. The Generic_ET_107_ETsz.CR1 and Generic_ET_107_ETsz_Windsonic.CR1 programs use the ConstTable() intruction to create a constants table that allows the user to easily input these values using Loggernet, PC400, or a keyboard display. These values only need to be set once, during station set up.

-
A CS106 Barometric Pressure Sensor can be added to the station. However, the sensor needs to be wired into the wiring terminal inside the enclosure, and the data logger program needs to be edited to include the instructions to poll the sensor and store the values.
Note: Some versions of the ET107 station that are interfaced with irrigation companies may have proprietary programs or complicated programs that are not easily changed.
-
Refer to the “Maintenance, Troubleshooting, and Schematics” section of the ET107 Weather Station Instruction Manual for procedural instructions.
-
Approximately 70 pounds. The total weight depends on the options selected for power supply (ac or solar) and wind speed and direction sensor.

If VisualWeather is used with the ET107, T107 (Toro), ET106, or MetData1, and the station has a standard configuration, setting up the station in VisualWeather is relatively simple. Select the station from the list in the Weather Station Network screen, and most of the work is automatically performed.
If, however, a custom station, a different station model, or a different variation for one of the sensors is used, it is necessary to set up a custom station in the Weather Station Network setup screens. In the Station Selection screen, select Custom.
Follow the screens that ask about the details of the station. Then, VisualWeather will connect to the station and get the names and fields of the data tables on the station where the data is stored. Because the names and fields of these tables are meaningless to VisualWeather, a mapping process must be used to map data table fields to fields and units that VisualWeather recognizes. This mapping allows VisualWeather to create screens and reports that are meaningful.
Because the data tables are often identified with a number and the fields are often cryptic, the mapping process can sometimes be confusing. To map fields for a custom station, contact Campbell Scientific for assistance.
-
Yes. A laptop can be connected to an RS-232 port on an ET107 to collect data. The SC115 (CS I/O-to-USB Flash Memory Drive) can also be used, but the data logger program has to be configured for use with the SC115.
-
Calsense Command Center software can interface with Campbell Scientific’s VisualWeather software, which can retrieve values from the ET107. In the Command Center software, setting up a station involves connecting to the VisualWeather LoggerNet server and selecting variables from the weather station’s listing for wind speed, rainfall, and ETo.
-
No. VisualWeather must be purchased separately.

Campbell Scientific recommends the following maintenance schedule:
- Once a week: check the rain gage funnel, and clean as necessary.
- Once a month: check the solar radiation sensor, and clean as necessary.
- Every 3 months: clean the temperature/RH radiation shield.
- Every 6 months to 1 year: replace the two desiccant packs (pn 4905).
- Every 1 to 3 years: have Campbell Scientific replace the wind speed bearings and reed switch. Request a return material authorization (RMA) number by following the steps listed on our Repair and Calibration page.
- Every 1 to 3 years: replace the relative humidity chip (pn 9598).
- Once every 3 years: have Campbell Scientific calibrate the solar radiation sensor. Request a return material authorization (RMA) number by following the steps listed on our Repair and Calibration page.
- Once every 5 years: have Campbell Scientific calibrate the rain gage sensor. Request a return material authorization (RMA) number by following the steps listed on our Repair and Calibration page.
- Once every 5 years: have Campbell Scientific calibrate the data logger. Request a return material authorization (RMA) number by following the steps listed on our Repair and Calibration page.

The communications options include direct serial connection, short haul modem, analog phone modem, cellular phone modem, radio, and Wi-Fi. Also, with an enclosure alteration, an Ethernet port can be added.
Note: Some of the listed telemetry options can drastically alter the power budget of the station.

To post data on a website, the data from the station needs to be regularly collected and put into a viewable format. Campbell Scientific offers two software options that can perform scheduled data collection: LoggerNet and VisualWeather.
VisualWeather is a simple solution that can be used either to connect to the station and monitor data or to set up scheduled data collection. VisualWeather also has powerful reporting capabilities that can be automated. If desired, the screens and reports can be transferred via FTP to a user’s website. A sample site is available for viewing. Using a mouse, hover over the Logan_Utah field in the upper left corner of the web page to view the reports we have selected to generate.
LoggerNet can also be used either to connect to the station and monitor data or to set up scheduled data collection. LoggerNet has more power and flexibility than VisualWeather, but it requires more time and knowledge to implement. For example, LoggerNet comes with an RTMC development tool to create a screen similar to the one in VisualWeather and display the data, but LoggerNet requires that the user learn how to use the RTMC software. In addition, LoggerNet has the ability to transfer data via FTP, but the transfer needs to be set up as a task and then scheduled with the LoggerNet Task Manager.
