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

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.

What is a sensor according to the Rae?

A sensor is a device capable of detecting external or internal actions such as: temperature, humidity, pressure, conductivity, etc. and transmit them properly 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.
  • Irrigation flow measurement.

Plantae Product

Sensor of subsoil moisture

El sensor consta de dos varillas que pueden tener distintas profundidades según el tipo de cultivo. Puede ir externo con las varillas enterradas o el sensor totalmente enterrado si el interesado lo considera, como es el caso de un campo de golf y de algunos cultivos (se reduciría la distancia de comunicación).

Una vez detectada la humedad se envía la señal de forma inalámbrica a un receptor que a su vez la envía a la plataforma. A través de ese cúmulo de tecnologías RF+GPRS se accede a la información desde móvil o PC en tiempo real, informando al cliente de la necesidad o no de regar.

Indoor or outdoor temperature sensor

Measure:

  • subsoil temperature indicating the risk of frost or heat waves. Send data in real time every hour. Essential to detect possible occurrences of fungi and other diseases if the information is combined with the humidity data of the subsoil. Also for the control of stomatal closure by temperatures above 35º.
  • La temperatura ambiente, que informa cada hora de los posibles cambios y oscilaciones en la temperatura.

Conductivity sensor

Measurement of the conductive trend on land.

The soil has salts in its organic composition, but the irrigation water increases this amount of You go out as we already indicated in other articles . The greater the quantity 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 on the root system. The effort to extract the water increases so much that the plant deteriorates.

A salt control combined with humidity control is essential for the health of the crop.

Flowmeter

Un caudalímetro inalámbrico mide la acumulación de riego, litros aplicados y eficacia. Podemos saber en tiempo real si el riego se ha efectuado o si ha disminuido por una posible rotura.

Hub-receptor recibe la información de los sensores

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.
