Abstract

Silos are best way to store the food grains. In silos, temperature and humidity affects the quality of food grains in storage and cause lessen in oil composition, color and many other characteristics. The temperature and humidity are the important parameters in maintaining the quality of the food grain during storage. Monitoring in silos is usually done by using a temperature reading device like RTDs, Thermistors or by using an inflexible, offline system which causes logging of data. The wireless transmission system is needed in order to send the data wirelessly to get the high data accuracy with less errors. The proposed system consists of transmitter node and receiver node, transmitter node includes an Arduino promini microcontroller unit, a LoRa RA02 module, and a BME280 sensor that measures temperature, humidity and transmits both the values to the receiver node with the help of LoRa. The transmitter nodes are made wireless by providing power through AAA batteries. The receiver node which is connected to gateway called harvester reads the data from receiver node and sends to the cloud database, using IOT data is viewed in the dashboard online with help of Node-Red platform. The proposed system achieves long range wireless data transmission with range up to 500m with high accuracy, low cost, low power consumption of 0.045W of each transmitter node.
仓内温湿度监测
筒仓是储存粮食的最佳方式。在筒仓中,温度和湿度会影响储存中的粮食的质量,并导致油脂成分、颜色和许多其他特征的减少。在贮藏过程中,温度和湿度是保持粮食品质的重要参数。竖井中的监测通常通过使用温度读取设备(如rtd、热敏电阻)或使用不灵活的离线系统(导致数据记录)来完成。为了获得高的数据精度和更小的误差,需要无线传输系统进行数据的无线传输。本系统由发送节点和接收节点组成,发送节点包括一个Arduino promini微控制器单元、一个LoRa RA02模块和一个BME280传感器,该传感器测量温度、湿度,并通过LoRa将这两个值发送给接收节点。发射机节点通过AAA电池供电实现无线化。连接到称为收割机的网关的接收节点从接收节点读取数据并发送到云数据库,使用物联网数据在node - red平台的帮助下在线查看仪表板。该系统实现了距离达500m的远距离无线数据传输,精度高,成本低,每个发射机节点的功耗仅为0.045W。
