Monitoring of Temperature Through a Sensor Network to Improve the Water Usage in Agriculture. Terra Latinoam [online]. 2023, vol.41, e1626.  Epub 16-Fev-2024.

Technological trends are present in different areas, in the case of agriculture, it is possible to find applications such as automated greenhouses. However, for a large part of small producers in countries with conditions like Mexico, this type of technological advance means a difficult investment to make. Fortunately, today, it is possible to improve the productivity of the field with affordable technology. In this work, the development of electronic devices to measure the temperature inside a 1000 m2 greenhouse is described. These sensors have the capability to form a network, with which the temperature of various points within the greenhouse was obtained. The information collected was concentrated on the internet and through an interpolation algorithm, those areas with the highest temperature were determined. This allowed punctual and localized irrigation therefore making water use efficient. These research notes are the first part of a project to develop affordable electronic devices capable of measuring climatic variables such as temperature, relative humidity, and light, among others. With the data obtained, the evapotranspiration coefficient can be calculated to estimate the amount of water needed in each crop area.
