Optimizing irrigation is the fundamental objective of Plantae . Sensors to optimize irrigation water and conductivity, measuring at different depths, adapt to all types of garden.

It is unthinkable today that it is irrigated 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.

What is a Rae sensor?

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.

The sensors have multiple applications but we are going to focus on those that Plantae produces for all types of crops and gardens.

Sensors to optimize irrigation water and salinity

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

  • Subsoil humidity at different depths.
  • Subsoil temperature and ambient temperature.
  • Electric conductivity.
  • Measurement of irrigation flow.

Detailed description of the sensors to optimize irrigation water and salinity

Humidity sensor to optimize water

The subsoil humidity sensor consists of two rods that can have different depths depending on the type of crop, garden or grove. It can go external with the rods buried or the sensor completely buried if the interested party considers it, as is the case of 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 water.

Temperature sensor


  • The subsoil temperature indicating the risk of frost or heat waves. Send real-time data every hour. Essential to detect possible occurrences of fungi and other diseases if the information is combined with the moisture content of the subsoil.
  • The ambient temperature, That informs the technician every hour of possible changes.

Conductivity sensor

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 the irrigation water increases this you leave as we already indicated in other articles . The greater the amount of salts, the greater the electrical conductivity.

The excess of salts damages the normal development of the plant. The absorption of the water it needs is altered by the pressure exerted by the salts in 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 absorption rate and the salts do not accumulate.

A 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 that are 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 observed in graphs with measurements in real time. Weekly, biweekly and weekly reports are also evaluated.

A team of technicians advises on irrigation cycles, water needs and salinity status.

Plantae already conquers the Peninsula and Algeria

The need for control of irrigation water by farmers, soccer and golf fields, the botanical gardens of Madrid and Barcelona and the Zarzuela racecourse make our technology advance exponentially, in all types of crops and garden.

An example of this is the following map:
