Abstract(s)

During food transportation, products are often subject to conditions which in no way promote the conservation of their biological properties. As a result of this loss of quality, there is a decrease in appreciation under the product. But more important than the loss of economic value is food waste. Remote monitoring systems, whose fundamental requirements relate to range and autonomy, make use of communications technologies to map characteristic crop parameters to reduce unnecessary application of resources or materials. This article proposes a monitoring system to record the conservation conditions inside refrigeration plants and vehicles, transmitting them via the internet of Things (IoT). This device is composed of an ARDUINO UNO Rev3 microcontroller that acquires the temperature and relative humidity every 5 minutes by means of a DHT 11 sensor, and uses the SIM800L module that provides real time communication data via GSM. It also incorporates a 3.7 V - 2600mAh battery which gives you an approximate 60 hour power range.
