YGC-CSM-2 MINI Ultrasonic Environmental Monitor — Wind Speed & Direction

Product Introduction

The YGC-CSM-2 MINI Ultrasonic Environmental Monitor is a highly cost-effective device designed specifically for accurate wind speed and wind direction measurement. Featuring a low-power chip design, the 2-element model consumes only about 0.27W, making it exceptionally suitable for solar-powered or battery-backed deployments where energy efficiency is critical. Its compact, newly designed structure measures just 80 mm in diameter and 100 mm in height, minimizing installation footprint.

Unlike traditional mechanical anemometers, this ultrasonic sensor has no moving parts, ensuring maintenance-free, 24/7 continuous monitoring in outdoor environments. It outputs both wind speed (0–45 m/s) and wind direction (0–360°) simultaneously via the standard RS485 Modbus-RTU interface for seamless integration.

Furthermore, the MINI series offers excellent scalability. Based on specific project requirements, users can easily upgrade the device with optional modules—including air temperature, humidity, air pressure, rainfall, illuminance, or solar radiation—without changing the base structure.

Its reliable performance and modular design make the YGC-CSM-2 ideal for a wide range of applications, including agricultural micro-meteorology, smart streetlights, scenic area environmental monitoring, and highway weather stations.

Product Features

• Dedicated 2-in-1 Measurement: Accurately measures wind speed (0–45 m/s) and wind direction (0–360°) with no mechanical moving parts.
  
  

• Ultra-Low Power Consumption: Total power is only approx. 0.27W, making it ideal for solar-powered, battery-backed, and off-grid deployments.
  
  

• Advanced Weather Compensation: Utilizes an efficient filtering algorithm to ensure stable and consistent data output, even in heavy rain and fog.
  
  

• Compact & Modular Design: Minimalist Ø80mm structure for easy integration into smart streetlights, micro weather stations, and grid-based networks.

• 100% Factory Tested: Individually calibrated in a wind tunnel to ensure high precision that meets strict industry standards.

Technical Parameters

Palm-Sized, Ultra-Compact Design

High Precision & Reliable Performance

Reliable 24/7 in Extreme Cold

Engineered for all-weather adaptability, the sensor is rigorously tested against extreme temperatures, water, and salt spray. It continues to deliver stable data in sub-zero environments without the need for internal heating (except in icing conditions).

Testing

Reliability Testing

Designed for ice, snow, and freezing rain, the built-in heating function prevents the probe from freezing. Even after rigorous testing at -40°C, the probe operates reliably with the heater activated.

Rigorous Quality Control

Every sensor undergoes rigorous wind tunnel testing. We generate precise wind speeds, compare the sensor's readings against reference standards, and verify that all measurements fall strictly within the allowable error margin before shipment.

Quality Assurance & Testing

Products are subjected to rigorous thermal cycling in our environmental chamber. This ensures they maintain factory calibration accuracy and prevent data drift under extreme temperature fluctuations.
