Sensors to optimize irrigation water and salinity in your gardens

Optimizing irrigation is the fundamental objective of Plantae. The sensors/probes to optimize irrigation water and conductivity, measuring at different depths, adapt to all types of gardens.

It is unthinkable today that it is watered by eye with the amount of technical means that we can find.

For a good control of the crop we have to apply precise measurements, not only of humidity, but also of subsoil temperature, ambient temperature, conductivity and flow.

Sensors according to the Rae?

A sensor is a device capable of detecting external or internal actions such as: temperature, humidity, pressure, conductivity, etc. and transmits them appropriately to a receiver.

Sensors have multiple applications, but we are going to focus on those produced by Plantae for all types of crops and gardens.

Sensors to optimize irrigation water and salinity

The sensors that allow optimization of water and salinity with Plantae technology are:

  • Subsoil moisture at different depths.
  • Subsoil temperature and ambient temperature.
  • Electric conductivity.
  • Irrigation flow measurement.

Detailed description of sensors to optimize irrigation water and salinity

Humidity sensor to optimize water

The subsoil moisture sensor consists of two rods that can have different depths depending on the type of crop, garden or trees. It can go external with the rods buried or the sensor totally buried if the interested party considers it, as is the case with a golf course.

Once the humidity is detected, the signal is sent wirelessly to a receiver, which in turn sends it to the platform. Through Nb-IoT technology, it is received on the mobile or tablet in real time, informing the farmer of the need or not to irrigate.

  • Ambient temperature, which informs the technician every hour of possible changes.

Conductivity sensors

It is not only important to measure with sensors that optimize irrigation water, it is essential to combine the information with other measurements, such as conductivity.

The soil has salts in its organic composition, but irrigation water increases this amount of sales as we indicated in other articles. The higher the amount of salts, the higher the electrical conductivity.

The excess of salts harms the normal development of the plant. The absorption of the water it needs is altered by the pressure exerted by the salts on the root system. The effort to extract the water increases so much that the plant deteriorates.

The short and frequent irrigations, always controlled, make the plant have a perfect rate of absorption and the salts do not accumulate.

Salt control combined with humidity control is essential for the health of the garden.

Hub-receiver receives information from sensors to optimize irrigation water

All the information sent by the sensors is received by the Hub-receiver that can work with a solar panel or connected to the electrical network.

The data is received by radio frequency with a range of 700 meters.

Other Plantae technologies to optimize irrigation water

To complement the use of sensors to optimize irrigation water and salinity, Plantae also carries out a granulometric study of the soil: texture, pH, macronutrients, etc.

All this complemented with satellite images that indicate the correct installation of the sensors to optimize the water.

All the alerts detected by the sensors to optimize water and salinity, in addition to preventing diseases such as fungi or deterioration of the roots due to waterlogging, are shown in graphs with real-time measurements. Weekly, fortnightly and weekly reports are also evaluated.

Plantae already conquers the Peninsula, France, the Dominican Republic and Algeria

The need for farmers to control irrigation water, football and golf courses, the botanical gardens of Madrid and Barcelona and the Zarzuela racecourse mean that our technology is advancing exponentially, in all types of crops and garden.

An example of this is the following map:
