Smart Agro It is Esular's smart fertilizer dosing solution. It works integrated with EC and pH sensors to automatically dose fertilizer according to the plant's needs. Fertigation automation prevents fertilizer waste, improves plant health, and increases yield.

Esular technologies are primarily used in the following areas: open field farming (drip, sprinkler, rain gun), greenhouse systems, pivot irrigation, vertical farming and hydroponics, park & garden landscaping, low-pressure irrigation systems and industrial water management.

Esular soil moisture sensors Can be installed at different depths such as 10cm, 20cm, 30cm, 40cm, and 60cm. The most suitable installation depth is determined according to the plant root zone depth. For example; 20-30cm is recommended for vegetable and fruit gardens, 30-40cm for field crops, and 40-60cm for fruit trees.

Esular soil moisture sensors measure three basic parameters:
Volumetric Water Content (VWC): Percentage of water in the soil.
Soil Temperature: Root zone temperature (°C).
Electrical Conductivity (EC): Salt and fertilizer concentration in the soil. These data are evaluated together to make optimal irrigation decisions.

Sensor data via LoRa wireless communication to the central station are transmitted. Data Esular web platform and can be monitored in real-time in graphical format via the mobile application. Historical data can be reported, and automatic notifications can be received when threshold values are exceeded.

The volumetric water content data obtained from the soil moisture sensor is compared with the lower and upper threshold values set by the user. When the moisture level falls below the lower threshold, irrigation automatically starts; when it reaches the upper threshold, it stops. This ensures the ideal moisture level is maintained without the plant experiencing water stress or excessive irrigation. Sensor-based irrigation, compared to timer-based irrigation, 30-50% water savings can provide.

Esular soil moisture sensors are maintenance-free. Thanks to stainless steel probes and an IP68 protection class body, they provide long-lasting use. The sensor does not need to be removed from the soil at the end of the season; however, in very cold climate regions, it is recommended to check superficial installations for frost protection. Battery replacement is typically done every 1-2 years.

E-Series central stations It features remote access via GSM/4G connection, optional 1-5W solar panel support, and capacity suitable for large-scale projects. The F-Series, with its more compact structure, is ideal for small and medium-scale projects. Both series use LoRa wireless communication technology and to the Esular cloud platform is connected.

With Esular's LoRa wireless communication technology, in open areas up to 5 km range is provided. Range may vary depending on terrain, obstacles (buildings, trees, etc.), and antenna position. The range can be further increased by using an external high-gain antenna.

to Esular central stations up to 128 wireless valve control unit can be connected. Each valve control unit can control multiple solenoid valves. This allows large-scale agricultural irrigation projects to be managed with a single central station.

Yes. Communication between the central station and valve control units is provided via LoRa radio frequency, requiring no internet connection. However, for remote monitoring and control, the central station needs internet access via a GSM/4G connection. Even if the internet connection is lost, pre-loaded irrigation schedules will continue to operate automatically.

Esular wireless valve control units have a very long battery life because they operate with 9V DC Latch technology. Under normal use, 1-3 irrigation seasons no battery replacement is required. Battery level can be monitored from the mobile application, and a low battery alert is automatically sent.

Irrigation schedules can be created via the Esular mobile application or web platform is easily created via. Weekly/daily calendar, time and duration-based programming, sensor-based automatic irrigation (soil moisture threshold values), and manual open-close options are available. The created programs are wirelessly transmitted to the central station and valve control units.

Esular pivot central management system enables wireless monitoring and control of all pivot machines from a single platform. Key features include:
• Wireless pivot control: Pivot start, stop, forward-reverse direction change, and speed settings are remotely controlled from the mobile application and web platform.
• GPS location tracking: The pivot's instantaneous position, rotation angle, and speed are monitored live on the map.
• Smart pressure monitoring: Water pressure in the pivot line is continuously measured, and alerts are sent in abnormal situations.
• Pump matching: The pivot and pump system are operated in coordination.
• Sectoral irrigation: Different amounts of water are supplied to different areas.

Esular wireless pivot control system operates via a digital control unit integrated into the pivot control panel. With GSM/4G connection, to the Esular cloud platform are connected. Starting, stopping, forward-reverse direction change, rotation speed adjustment, and sectoral irrigation parameters of the pivot are controlled remotely via the mobile application or web interface. Even if the internet connection is lost, local programs continue to run.

A GPS module placed at the end of the pivot (last tower) continuously reports the machine's instantaneous position, rotation angle, and speed. This data On Esular platform are visualized on the map. Past rotation records and route history are stored, allowing irrigation performance to be analyzed. Automatic actions can be triggered when defined sector boundaries are reached.

Smart pressure monitoring continuously tracks water pressure in the pivot line, ensuring system safety and efficiency. In cases of pressure drops (burst pipe, clogging, etc.) and excessive pressure, instant alert are sent, and the pump is automatically stopped if necessary. Pressure data can be compared with past records to monitor the system's health. Through pump matching, pressure and flow rate data are coordinated and optimized.

Esular pivot pump matching coordinates the pivot machine with the pump system at the water source. When the pivot starts, the pump automatically engages; when the pivot stops, the pump is also shut off. By working integrated with pressure sensors, the pump is ensured to operate within its efficient pressure range. This matching saves energy and eliminates the risk of the pump running dry.

Esular converts existing mechanical pivot machines into digital automation systems. During the conversion process:
• The mechanical control panel is replaced with an Esular digital control unit.
• A GSM/4G wireless communication module is added.
• A GPS location tracking module is installed.
• Pressure sensors and pump matching system are integrated.
The conversion is achieved by modernizing only the control electronics, without altering the mechanical structure of your existing pivot machine. This way, your old pivot, into a fully remote-controlled smart pivot system transforms. It works independently of brand and model.

Sectoral irrigation is a method of applying different amounts of water to different areas (sectors) during the rotation of a pivot arm. With the Esular system, separate irrigation parameters can be defined for each sector using GPS location data. This allows for optimal irrigation of parcels with different crop types or soil structures under the same pivot. Soil moisture sensors when integrated with, the amount of water is automatically adjusted according to the actual moisture status of each sector.

A solenoid valve operates with an electromagnetic coil and opens and closes in less than 1 second. The 9V DC Latch version can operate with a battery. A butterfly valve, on the other hand, operates with a 24V AC electric actuator motor, provides gradual flow control, and takes ~30 seconds to fully open. Solenoid valves are preferred in agricultural irrigation, while butterfly valves are preferred in industrial automation and large-scale infrastructure projects. For a detailed comparison, to our valve selection guide you can refer.

Plastic solenoid valves It offers 10 bar (PN10) pressure resistance, diameters up to 6 inches, a lightweight body, and full corrosion resistance, making it the most preferred valve type in agricultural irrigation due to its economical price. Cast solenoid valves, on the other hand, are ideal for industrial applications and high-pressure systems with 16 bar (PN16) pressure resistance and diameters up to 10 inches. For a detailed comparison, to our solenoid valve guide göz atabilirsiniz.

DC Latch (latching solenoid) is a technology that changes the valve position with a short electrical pulse and maintains its position even if power is lost. 9V DC Latch valves consume only millisecond pulse current, thus, hundreds of open-close cycles can be performed with a single 9V battery. It is ideal for wireless and solar-powered irrigation systems. The 24V AC alternative is used in facilities requiring a fixed grid power supply.

Esular plastic solenoid valves are produced in a diameter range from ¾ inch to 6 inches. According to connection types: threaded (¾"-2½"), angled threaded (2"-2½"), flanged (3"-6"), angled flanged (¾"-4") and large body threaded models are available. Cast solenoid valves offer diameter options up to 10 inches.

Factors to consider when choosing a solenoid valve: project pressure value (PN10 or PN16), pipe diameter, connection type (threaded or flanged), energy source (9V DC Latch or 24V AC), and application area. Plastic threaded solenoid valves are preferred in garden and small agricultural projects; flanged in large-diameter projects; and cast solenoid valves in industrial high-pressure facilities.
