As a consequence of deployment advantages of the Wireless

Sensor Networks, the environmental monitoring of greenhouses parame-

ters have been a widely used scenario for this technologies as a branch of

the Precision Agriculture. In this research we propose an IoT architec-

ture for this particular application. A Wireless Sensor Network (WSN)

is designed based in the Zolertia Z1 mote, for the collection of luminous

intensity, air temperature, soil moisture and relative humidity in dier-

ent points of actual greenhouses. It is also developed, a Raspberry Pi 3

model B IoT Gateway based in the ThingsBoard IoT Gateway platform.

It is implemented in this gateway basic data pre-processing and data

persistence capabilities giving the application some Fog Computing fea-

tures. At the cloud level is implemented a ThingsBoard cluster platform

which could access the information about the network devices through

the MQTT protocol. A dashboard is designed in order to monitor the

environmental parameters and to test the given proposal.
