Automatic Weather Station (AWS)
Autonomous solar-powered station measuring rainfall, wind speed, wind direction, temperature, relative humidity, and barometric pressure on one cloud dashboard.
Introduction
Local microclimate intelligence for disaster resilience and planning.
Regional weather reports from airport radars are too generalized for industrial plants, open-cast mines, agricultural estates, and solar power parks. Bulfro Aqua ESG’s Automatic Weather Station (AWS) delivers site-specific microclimate data in real time. Powered by a rugged solar harvesting system with 15+ days battery backup, it tracks sudden pressure drops, gusting winds, and heavy rainfall to trigger early disaster warnings.
Meteorological System
Autonomous Microclimate Telemetry
Heavy storms, high crosswinds, and sudden heatwaves present severe operational hazards to outdoor cranes, solar panel trackers, mining haul roads, and agricultural harvests. Bulfro Aqua ESG AWS provides localized weather awareness seconds after changes happen.
The galvanized weather mast mounts precision sensors aligned to World Meteorological Organization (WMO) standards. An integrated 4G / LoRaWAN data logger timestamps each channel and broadcasts real-time dashboards to operations teams.

Frequently Asked Questions
Frequently Asked Questions
Find direct answers to common questions regarding AWS weather sensors, solar autonomy, mast installation, and calibration.
The standard Bulfro Aqua ESG AWS includes 6 core parameters: rainfall (0.2 mm tipping bucket), wind speed, wind direction, ambient air temperature, relative humidity, and barometric air pressure. Additional sensors like solar radiation (pyranometer) or soil sensors can be added modularly.
The system is equipped with an industrial-grade LiFePO4 battery pack and smart power management. It operates continuously for over 15 to 30 days during overcast monsoon conditions without receiving any direct sunlight.
Yes. The galvanized mast and sensor bodies are rated to survive wind velocities up to 150 km/h. A solid copper lightning spike is mounted at the top of the mast with dedicated heavy-gauge grounding down-conductor to protect electronic loggers from direct lightning strikes.
The integrated data logger uses a 4G/GPRS modem to upload readings every 10–15 minutes to the Bulfro Aqua ESG Cloud. Users can view graphs, live dials, and historical reports via desktop web browsers and mobile apps. Real-time RS-485 Modbus RTU is also available for plant SCADA.
Yes. You can configure custom thresholds for wind gusts (e.g. > 45 km/h for crane safety), heavy cloudburst rainfall rates, or temperature spikes. When thresholds are breached, the system sends instant SMS notifications and email alerts to safety officers.
Minimal maintenance: periodic inspection and wiping of the solar panel surface, clearing debris from the rain gauge funnel mesh, and an annual calibration check of wind and temperature sensors as per standard meteorological guidelines.
