Application Case

◂ Pain Point▸

Fig plantations suffer from insufficient real‑time growth environment data, inefficient manual irrigation causing water waste or shortage, and poor unified management amid expanding planting scale, which leads to unstable fig yield and high labor costs.

◂ Solution▸

EM500‑LGT LoRaWAN Light Sensor — Captures orchard illuminance vital for fig photosynthesis, supports long‑term outdoor deployment with long battery life and IP‑grade protection
EM500‑SMTC Soil Sensor — Monitors soil moisture, temperature and conductivity for irrigation reference
EM500‑CO₂ Multi‑parameter Sensor — Detects CO₂, temperature, humidity and barometric pressure for orchard micro‑climate assessment
UC511 Solenoid Valve Controller — Performs cloud commands to enable automatic irrigation
UG67 Outdoor LoRaWAN® Gateway — Collects field sensor data over long‑range LoRaWAN®, no field cabling needed
Milesight IoT Cloud Platform — Provides 24/7 remote monitoring, unified device management and smart data analysis

Result: Optimized growing conditions improve fig quality and output. Automatic irrigation reduces labor and water waste. Cloud‑based centralized management simplifies large‑orchard operation; scalable LoRaWAN® solution lowers total operating expenses.
