CONTROLLER FOR IRRIGATION AND WINDOWS CONTROL, MAHER SMART

MAHER SMART is an agricultural controller for irrigation automation and window control in a greenhouse.

  • Window and fogging control. In addition to irrigation, it also controls windows and misting in a greenhouse.
  • Easy to use. Thanks to its 7” color touch screen.
  • Linux. The only controller that has this operating system.
  • Detailed reports. Schedule of planned irrigations, sensor readings, irrigation histories, etc. (Download reports by USB).
  • Advanced features. For fertigation with pH and electrical conductivity control.
  • Robust. Resistive type touch screen to withstand humidity and high temperatures.
  • V.P.D. Calculation It identifies unhealthy crop conditions derived from the environmental conditions of the greenhouse.

INFORMES Y GRÁFICAS

  • Consult data: Current irrigation and fogging, anomalies, program status, controller information, mix of two waters, diesel group and remote units.
  • Historical: Irrigation, fogging, valves, fertilizers, treatments, programs and total data. Reports can be downloaded in Excel format, via USB.
  • Risk forecast: Programmed irrigation schedule with detailed information.
  • Sensor reading and graph: Possibility to filter for a certain period.

ENTRADAS

  • 10 digital inputs. No voltage, fully configurable as impulse counters or detectors of different events and anomalies.
  • 6 analog inputs for connecting sensors to the controllers. These inputs are configurable in signal range and in input voltage range. Sensors with 4-20 mA or 0-5 V= output can be used. The function of each of these inputs is programmable.

Programming

MAHER SMART has 20 independent programs for irrigation and fogging.  The program data can be modified during execution and is effective with no need to stop irrigation or fogging.

  • 10 valves per program that irrigate independently or grouped
  • Delay pump start/stop and close valves to avoid water hammer.
  • Interrupt irrigation due to registered anomaly.
  • 3 irrigation stop conditions due to the status of a digital input or remote unit or due to reading a sensor connected to the controller’s analog inputs. For fogging, two stop conditions

IRRIGATION AND FOGGING

IRRIGATIONFOGGING
For fixed hours (up to three per day)Cyclic fogging
Cyclic irrigationBy relative humidity
Sequential irrigations (starts at the end of another irrigation schedule)By temperature
On demand (digital input)
Due to accumulated solar radiation
By analog input or sensor (temperature, humidity or EC of the soil, anemometer, etc.)
From remote units (the start is conditional on the digital input status or reading the sensors connected to remote units)

FERTILIZATION

SPECIFICATIONSFERTILIZATION TYPES
Injection of 8 fertilizerspH and EC control
The irrigation water pH can be controlled with acid or baseDifferential or incremental
Inject contributions or special treatmentsMix of 2 waters
Continuous time fertilization and pH control
Distributed time fertilization during irrigation time and pH control
Continuous volume fertilization and pH control
Distributed volume fertilization during irrigation time and pH control
Volume fertilization proportional to water volume and pH control
Fixed injection (injection period and % of each fertilizer)

WINDOW CONTROL

  • MAHER SMART controls up to 8 zones. Up to 6 windows can be controlled in each zone (3 groups of 2 windows), top or side.
  • Window opening and closing can be conditioned by the following sensors: wind vane, anemometer, humidity, temperature, rain and solar radiation detector.
  • Four schedules. Day, night, special 1 and special 2.
  • The sunrise and sunset time can be set manually or automatically with an astronomical clock

CONTROL OF THERMAL OR SHADING COVERS

In the programming of the cloths, we can edit the parameters for controlling the cloth of each control zone. For each control zone:

  • Shade cloth
  • – Shade cloth by solar radiation: Programming the position of the shade cloth based on the received solar radiation at any given time
  • – Shade cloth by schedule: Indicates the positioning of the shade cloth at specific hours.
    You can also use the option ‘Use astronomical clock’ to have the controller calculate and set the daily sunrise and sunset times
  • Thermal cloth by solar radiation: This is a screen that prevents the escape of the heat that accumulates inside the greenhouse during the hours of highest solar radiation. For this type of cloths, control is carried out by programming solar radiation references
  • Thermal cloth by temperature: This is a thermal screen where temperature is used as a reference for control

Models

MAHER SMART comes in different versions.
