Tellus dataset

The data were acquired through the IoT system using GPRS/2G between August to December crop 2021 during the tobacco plantation. The images are collected from 8 AM to 6 PM in 2/2 hours. The soil and microclimate data were collected all day in each 30 minutes. The telemetry station consisted of a solar controller connected between a 30 W solar plate (model RSM030P) and a 12V battery with a capacity of 12 Ah that powered a Raspberry Pi Model A+ device. Connected to the Raspberry was a sensor model BME-280, which carried out measurements of ambient temperature and humidity in addition to atmospheric pressure, a 2G/GSM modem model SIM808L and an Arduino model UNO. A relay model SRD-05 (5V 10A) turned on the Arduino periodically to send a set of information to the Raspberry via USB. In this set, that is, connected to the Arduino, there were the other sensors that collected data on soil temperature (model Ds18b20) and soil moisture (hygrometer model S12), luminosity (model Temt6000), direction and speed of the winds (WRF Commercial) .本数据集采集于2021年烤烟种植季的8月至12月，通过搭载通用分组无线服务/第二代移动通信（GPRS/2G）的物联网（Internet of Things, IoT）系统完成数据获取。图像采集时段为每日8时至18时，每2小时采集一次；土壤与微气候数据则全日采集，每30分钟采集一次。 该遥测站由太阳能控制器构成，该控制器连接30瓦太阳能板（型号RSM030P）与容量为12安时的12V蓄电池，为树莓派A+型号（Raspberry Pi Model A+）设备供电。树莓派外接型号为BME-280的传感器，可同步测量环境温度、湿度与大气压强，同时外接型号为SIM808L的2G/GSM调制解调器，以及型号为UNO的Arduino控制器。型号为SRD-05（5V 10A）的继电器周期性启动Arduino，使其通过USB接口向树莓派传输一组采集数据。该组数据对应的传感器均外接至Arduino，包括采集土壤温度的Ds18b20型号传感器、采集土壤湿度的S12型号湿度计、采集光照度的Temt6000型号传感器，以及采集风向与风速的WRF商用传感器。
