ESTRON
Why ESTRON?
The technology behind smart irrigation, topic by topic: from water savings to LoRa range.
The xeriscape decree: what changes in park irrigation?
A Presidential Decree in force since 18 October 2025 asks three things of park, boulevard and median irrigation in Türkiye: pressurised and automated irrigation, metered and recorded water use, and a yearly data report to the Ministry. This article summarises the irrigation articles of the decree and of the Water Efficiency Regulation, and shows which article ESTRON answers and how.
Read →How to winterize an irrigation system and open it in spring
When the irrigation season ends there are two jobs: protect the system from frost and go into spring with a clean record. This article gives six steps for shutdown, six for start-up and a maintenance calendar for the year. The battery valve controller stays in place over winter; the schedule is stopped from the panel.
Read →How is lawn watering time calculated?
"How many minutes should a lawn be watered?" has no single answer; it has a calculation. The time depends on the lawn's water demand that day, the rain that fell and the sprinkler flow rate. This article gives the calculation in four steps, works an example for 100 m² and explains how ESTRON does the same calculation automatically every day.
Read →Public garden irrigation: dozens of lines, one panel
A "millet bahçesi" (public garden) is a large, open space that is always open to the public. Its irrigation is split into dozens of lines; the valves are scattered; most have no electricity. This article shares what ESTRON learned in TOKİ public gardens: line planning, gateway placement, battery controllers, leak alarms and the daily decision.
Read →What is a solenoid valve and how does it work in irrigation?
A solenoid valve is a water valve that opens and closes electrically. There is one at the head of every irrigation line. The controller sends a short signal to the coil; the valve opens and the sprinklers run. This article covers the valve's parts, fault signs and how a battery controller is fitted to the existing valve.
Read →How does smart irrigation save water?
If your park only received exactly as much water as it actually needs, both your water bill and your energy costs would drop. That is precisely what ESTRON does: it tracks the weather, the soil and the condition of your plants, then delivers the right amount of water at the right time.
Read →Irrigation reporting: every run on record
The ESTRON panel logs every watering across your landscape with its date and time. At a glance you can see how much water each zone used, what the sensors measured and when the system ran.
Read →Rain sensor and weather-based irrigation
Weather-based irrigation has two parts: a forecast that postpones in advance if rain is coming, and a sensor that stops watering when rain starts. ESTRON uses both. This article explains the logic, where to mount the rain sensor and how to test it, and how it differs from the AI postponement.
Read →A secure connection for wireless irrigation control
ESTRON devices carry your data safely between the valve in the field and your phone. Your commands travel encrypted, no one can step in between, and only authorised people can reach your system.
Read →Irrigation automation: three generations, from timer to AI
Irrigation automation has gone through three generations: the timer that opens on the clock, the controller that stops on a sensor, and the AI that decides again every day. ESTRON is the third generation; it also does everything the first two do. This article compares the generations and explains how to move up without replacing the system.
Read →Hardware built for the field
ESTRON devices are designed to keep working for years out in the open, through rain and sun. Whether installed in a park, a median or an estate landscape, the hardware is protected against water, dust and the outdoor environment. The goal is simple: install it once and let it run for years without trouble.
Read →Low power consumption in a battery irrigation controller
A battery irrigation controller runs for years on 2 × 9 V batteries, with no cabling. The secret is simple: the device spends almost all its time asleep; it wakes only for the seconds it opens or closes the valve and sends data. This article covers what sets battery life, the difference from a wired cabinet, and mounting in the valve box.
Read →Irrigation with a soil moisture sensor: what it measures, how it decides
A soil moisture sensor measures how much water is left in the root zone. Placed in the right spot at the right depth it confirms the irrigation decision from the field; placed wrongly it reads wrongly. This article explains what the sensor measures, how the threshold is chosen, placement, and how ESTRON combines sensor data with satellite and weather data.
Read →Irrigation keeps running even without internet
In the field, the internet is not always reliable. Even when the connection drops, ESTRON devices keep running your schedule from their own memory; they store the data and quietly sync it back to the system once the connection returns.
Read →Catch water leaks without going to the field
ESTRON flow sensors continuously measure the water passing through each valve. When there is a leak, a blockage or a faulty valve, the system spots the anomaly and alerts you, so you learn about the problem before it grows, and without even going out to the site.
Read →LoRaWAN open standard: not tied to a single vendor
ESTRON devices use an open communication standard called LoRaWAN. This means your investment isn't locked to one brand; you can run the hardware and software with whichever supplier you prefer.
Read →SCADA integration: connecting ESTRON to your own systems
Municipalities, industrial zones and large facilities often track irrigation from their own monitoring centres (SCADA). ESTRON can connect to these centres, so irrigation data shows up on the screens your organisation already uses and everything is managed in one place.
Read →Irrigation control from your phone: Bluetooth on site, LoRaWAN from the office
There are two ways to open a valve from a phone. On site, Bluetooth: within 10 m of the valve, with no internet. From the office, LoRaWAN: the web panel or the app, wherever the valve is. This article covers both, the screen flow, and the task queue that sends commands to devices on their own as you walk the site.
Read →How far does LoRaWAN wireless reach?
LoRa is the long-range wireless technology behind ESTRON systems. It lets you reach sensors and valves spread across a large site without running any cables, all from a single gateway.
Read →How often do satellites image your park?
ESTRON relies on satellite images taken from space to track the condition of your plants. These images refresh every few days, so the greenness and water needs of your park stay up to date.
Read →Tracking water content from space (NDWI)
NDWI is an indicator that reads how much water your plants and soil are holding, straight from satellite imagery. ESTRON uses it to see, on your behalf, which parts of your site are running dry and which are still well watered.
Read →Tracking green areas from space (NDVI)
NDVI is a simple measure that shows, from satellite imagery, how healthy and green plants are. ESTRON uses this information to spot drought and stress in your landscape areas before they become visible to the eye.
Read →The shortcut to a faulty solenoid valve
In a large estate or park, finding a valve buried underground can take hours. ESTRON shows the faulty valve on a map and guides you right on top of it using the signal on your phone, cutting field time from four hours to half an hour.
