      <dc:description>Precision agriculture and smart farming are concepts that are acquiring an important&#xd;
boom due to their relationship with the Internet of things (IoT), especially in the search for new&#xd;
mechanisms and procedures that allow for sustainable and efficient agriculture to meet future demand from an increasing population. Both concepts require the deployment of sensor networks that&#xd;
monitor agricultural variables for the integration of spatial and temporal agricultural data. This paper presents a system that has been developed to measure the attenuation of radio waves in the 2.4&#xd;
GHz free band (ISM- Industrial, Scientific and Medical) when propagating inside a tomato greenhouse based on the received signal strength indicator (RSSI), and a procedure for using the system&#xd;
to measure RSSI at different distances and heights. The system is based on Zolertia Re-Mote nodes&#xd;
with the Contiki operating system and a Raspberry Pi to record the data obtained. The receiver node&#xd;
records the RSSI at different locations in the greenhouse with the transmitter node and at different&#xd;
heights. In addition, a study of the radio wave attenuation was measured in a tomato greenhouse,&#xd;
and we publish the corresponding obtained dataset in order to share with the research community.</dc:description>
