This article presents the results obtained in the evaluation of the LoRa technology as an alternative communication protocol for agricultural applications, by making measurements in situ in a rural area between the municipalities of Sibaté and Granada in Cundinamarca, Colombia. The device for testing was selected using a document search, thus choosing the TTGO esp32 board. Additionally, a temperature sensor and a variable resistance were included to obtain measurements from a transmitter node whose data was sent using the LoRa protocol to a receiver node with a distance of 500 meters between them and an approximate elevation gradient of 4° difference between the points. Finally, the information collected in the tests was subjected to a descriptive statistical analysis that allowed establishing the most reliable parameters of the protocol and identifying the appropriate spreading factor and bandwidth.
