Sensors

Keep getting Information.

Each IoT application will have different sensors, or even in the case of solutions for agriculture you can have different types of setup depending on the specific application. We will illustrate here the sensors used and the data obtained from them.

Sensors for Agriculture application

As ours is a prototype, we opted for a generic setup that would be useful and suitable for as many applications as possible. The fixed sensor core that we have built consists of:

Temperature, pressure and humidity sensor, providing general information about the environment around the plants, as well as, in the case of a greenhouse, giving information on automatic heating and humidification systems.

UV light sensor, allows you to monitor ultraviolet levels, which in high doses can inhibit photosynthesis and cause visible damage to the crop, a real risk especially in plastic greenhouses.

Soil moisture sensor, whose information enables automatic watering of plants only when needed, instead of at periodic intervals, reducing water consumption and avoiding waste.

In addition, in the case of the module designed for outdoors, we have also implemented an:

Rain sensor, which informs us about the weather conditions on our land if it is located far from where we live or in another microclimate.

Collected data

The data collected by the sensors, which are presented in this form:

Data = T:20.29 $ P:995.28 $ H:56.65 $ S:0 $ R:295 $ U:0

Are sent by external modules to the gateway and added to a file that can serve as a daily or weekly history of the data obtained, with a graphical interface that creates adaptive graphs to represent them.

Here are some examples of how the graphs can be displayed:
