Since the time when humans first started growing their crops they have been passing their knowledge and experience from one generation to the next.

This process created a false sense of security where we think we know when and how much plants should be irrigated, but it doesn’t always fit the actual plants’ needs.

In some cases farmer’s irrigation decisions could be incorrect or executed in wrong timing – as a result plants damaged by over irrigation or under irrigation.

Over Watering

Autonomous Irrigation

We have developed a technological solution that makes growing crops fully autonomous from irrigation and fertilization aspects.

Our system is fully capable of deciding when and how much to irrigate, and it executes the irrigation decision without human intervention.


How Does It Work?


Recent Achievements

During the last few years we have conducted many tests in which we have drastically reduced water and fertilizers consumption while increasing the yield.


Scientific Publications

Isaac Klein

Tevatronic CSO

Isaac Klein, Ph.D. (Researcher) investigated over 30 years irrigation of horticultural crops in the Volcanic Center, Agricultural Research Organization, Israel. His experience and approach served as a guide during the development process of our system. Below you can find a few publications written on pilot studies carried out with our system.


System Architecture



Wireless tensiometer is installed near the root system of one of the plants in the field (or in a green house). It transmits data on the amount of energy a plant’s root system uses to draw water from the soil, this way our system understands the actual needs of the whole crop in real-time.


Irrigation controller takes care of collecting data from near by soils sensors and sends it to cloud server for analysis. Based on commands sent back from server it opens and closes irrigation valves.


RF electronic valve controller triggers opening and closing states of the electronic valve. The unit gets command of changing valve state in a distance of a few hundred meters from Valve Switcher.


24/7 Always accessible on-line web server running proprietary mathematical algorithm for data analysis. It analyses the collected data from all soil sensors, makes the irrigation decision and sends it to the Valve Switch for execution.

System Modes

The Tevatronic irrigation controller consists of a digital tensiometer sensor, a valve switch controller and a remote valve control unit. The valve switch and the remote valve control units (enclosed together in a W 14.5 cm, H 9 cm, D 4 cm box) were developed specifically for the system and commanded from a cloud server on the Internet. The valve switch communicates with the tensiometer sensors with ultra high radio frequency (434MH) to a distance of up to 1 Km and with the cloud server via cellular communication, on the GSM/3G network. Tensiometers are equipped with a C2 battery, lasting for 3 years.
The irrigation controller can operate in several modes.

Tensiometers Array

Array of Tevatronic wireless tensiometers transmitting to central unit and through it to internet cloud server.

Automatic Mode

In this mode the controller operates as a conventional irrigation computer, requiring the input of irrigation timing and volume of water and % fertilizer injection.

Automatic with Decision Support

This mode is similar to Automatic Mode, but the system also suggests an irrigation time to the user.

Autonomous Mode

In this mode the system makes the irrigation decision when and how much to irrigate, based on the input by the user of the irrigation depth, the threshold tension to initiate the irrigation and % fertilizer injection.

Automatic Irrigation

Systems that start irrigation automatically, no matter what condition the plant is in. It can even start the irrigation cycle when it’s raining. Similar systems often require re-calibration to fit the weather changes. A few wrong irrigation cycles can either dry out your plants or strangle them with water.

Decision Supported Irrigation

Systems using various soil/weather/wind/light/humidity sensors to provide user with huge amounts of data and let him decide on when and how much each section should be irrigated. It requires a lot of user connectivity and intervention in the process – it also assumes they have the professional knowledge needed to make the decisions.

Autonomous Irrigation

Our solution uses only the most reliable information taken from the main roots system of the plant. It calculates both the amount of water in various depth of soil and the water consumption behavior of the plants. The system analyses this information and balances the amount of water in the plants AUTONOMOUSLY without any user intervention, though user can monitor the process.

System Benefits


Less equipment in your field means less technical problems & maintenance and simpler system utilization.


Never again, change the settings of your irrigation while trying to adjust them to the weather. The autonomous system will do it.


Monitor the system functionality and processes on the field or greenhouse from anywhere in the world.


Irrigation cycles autonomously executed by the system are fully correlating with photosynthesis of the plants.


Grow healthier plants by utilizing dynamic irrigation in which irrigation cycles are reaction to real plant’s state.


Drastically reduce the loss of water and fertilizers into the ground by controlling the depth of irrigation using web interface.


Be notified in case of various possible communication or infrastructure malfunctions on the field.


Using web interface farmers can have high precision control over the stress value & duration they wish to apply on the plants.

System Components

Online Control

Web based interface for irrigation and fertilization control for any type of fields, plants and green houses.

Using this control interface a farmer can monitor and adjust the operation of the system from anywhere on the planet.

The main parameters you can actually control are:

  • Water stress you wish to apply on your plants
  • The depth to which the water should get in the ground
