Probe Utilities

Probe Utilities now has a companion app for Android and iOS

We recently released mobile apps for Android and iOS that will allow customers to view their probe data (GPRS probes only for now) on their phones, wherever they might be.

Use the app to view the basics like Level and Sum Graph, as well as raw readings and probe status.

To install the app, search for "dfm dashboard" on either Apple App Store or Google Play Store, or have a look at the links below:


The DFM Probe Utilities software package is used to interpret the soil moisture content and temperatures of the DFM Continuous Logging Soil Moisture Probes. With the use of the accurate information from the probes, informed irrigation decisions can be made and implemented.

  • The Depth Graph allows the user to see how moisture moves through the profile of the block and also which areas are depleted quicker than others.
  • The Level Graph allows the user to view each sensor level together or independently. This allows the user to determine to which depth the irrigation penetrates the soil and if it necessary to adjust the irrigation time to prevent unnecessary depth wetting.
  • The Sum Graph allows the user to determine how long the last irrigation will last and when to apply the following irrigation. Full and refill points can be set, by the user, on the sum graph to indicate field capacity and at what point the soil is too dry.

The logger serves as the interface between the user and the probe. It can be used to:

  • Force readings (or take manual readings)
  • Show the value of the last reading taken
  • change the reading interval
  • Put probe into "Sleep" mode
The logger is powered by a 9V battery which is non rechargeable and easily replaced. The logger puts itself into "Sleep" mode to conserve battery power and has an RS232 interface to download the information.

DFM Probe Utilities provides the user with a Withdrawals section that can simplify the scheduling of irrigations. The program will determine the usage of the plant and how much moisture is available in the profile and estimate the next irrigation time according to these factors.

All irrigation records can be kept track of in the irrigation records section of the software, and keeps a total for the season. All irrigations that are recorded are also displayed on the level graph, and the sum graph, making it easier to determine whether the movement in the graphs was caused by irrigation or rain.

The Climate data section of the program stores all climate data such as Evapotranspiration, Rain, Temperatures (High, Low and Average), Relative Humidity (High, Low and Average), Radiation, Wind speed and Expected Evapotranspiration. Climate data can be automatically downloaded from the Davis Weather Station or entered by hand.

The software gives one an abundance of information that can be used to effectively and efficiently schedule, and more importantly is very user friendly.
