Internet of Things (IoT) was employed for monitoring the growth parameters of rocket (Eruca sativa) plants cultivated in a greenhouse under supplemental LEDs lighting. Red (R), blue (B) and the combination red and blue in different ratios (75R:25B, 50R:50B, 25R:75B), were employed, as well as white LEDs. The LED lamps were automatically turned on at 18:00 and off at 24:00. Thus, the plants were grown in an 18 h photoperiod until the harvest time under daylight supplementary lighting (i.e. 12 h sunlight and 6 h LED). Yield, biomass, leaf area (LA), leaf area index (LAI), leaf area rate (LAR), leaf weight rate (LWR), specific leaf area (SLA), relative growth rate (RGR), crop growth rate (CGR) and net assimilation rate (NAR) of rocket plants were investigated, through sensors of temperature, humidity and light intensity via a Raspberry Pi board by the Message Queuing Telemetry Transport (MQTT) communication protocol. ANOVA results demonstrated that 50R:50B LEDs lighting produce higher yield, total biomass, LA, CGR, LAI, LWR, as well as lower SLA as compared to other treatments. Reliability analysis showed that IoT monitoring system is stable and reliable for controlling of environmental conditions (i.e., temperature, humidity) of the greenhouse.

在补充 LED 照明下使用物联网监测火箭 (Eruca sativa) 生长参数

物联网 (IoT) 用于监测火箭 ( Eruca sativa)的生长参数) 在补充 LED 照明的温室中栽培的植物。采用红色 (R)、蓝色 (B) 和不同比例的红色和蓝色组合(75R:25B、50R:50B、25R:75B),以及白色 LED。LED 灯在 18:00 自动打开,在 24:00 自动关闭。因此,植物在 18 小时光周期中生长,直到在日光补充照明(即 12 小时阳光和 6 小时 LED)下的收获时间。产量、生物量、叶面积(LA)、叶面积指数(LAI)、叶面积率(LAR)、叶重率(LWR)、比叶面积(SLA)、相对生长率(RGR)、作物生长率(CGR) ) 和火箭植物的净同化率 (NAR),通过消息队列遥测传输 (MQTT) 通信协议,通过 Raspberry Pi 板通过温度、湿度和光强度传感器进行研究。方差分析结果表明,与其他处理相比,50R:50B LED 照明产生更高的产量、总生物量、LA、CGR、LAI、LWR,以及更低的 SLA。可靠性分析表明,物联网监控系统对温室环境条件(即温度、湿度)的控制稳定可靠。
