Abstract:
Aiming at the problems and limitations of temperature collection in the large-scale processing and storage of agricultural products,a new temperature collector based on LoRa wireless communication was proposed,and the hardware and software design and performance test of the device were introduced.The device adopts a multi-temperature sensor and a single bus structure,which can realize multi-point,continuous,real-time,and online detection of temperature.It has the advantages of simple structure,stable performance,low power consumption,and long transmission distance.It is practically used in food storage and tea processing,and the effect is obvious.The device can meet the requirements for the processing and storage of different types of agricultural products,and have a very important promotion significance for reducing labor,ensuring the quality of agricultural products,and reducing losses in the processing and storage of agricultural products.It can have a wide application prospect.
