Product Introduction

The KH.CQX-6 All-in-One Ultrasonic Weather Sensor with 304 stainless steel housing is a high-precision six-parameter meteorological monitoring instrument designed for long-term outdoor deployment in smart agriculture, automatic weather stations, environmental observation networks, and harsh weather environments.

Integrating six essential meteorological parameters — wind speed, wind direction, air temperature, relative humidity, atmospheric pressure, and rainfall — the sensor provides comprehensive real-time environmental data through a compact all-in-one design.

The KH.CQX-6 adopts advanced frequency-converting ultrasonic technology for wind measurement, eliminating mechanical wear, startup errors, and measurement instability caused by traditional rotating sensors. The integrated rainfall measurement function enables efficient precipitation monitoring without requiring multiple separate instruments.

Its corrosion-resistant 304 stainless steel housing provides excellent durability in coastal, marine, industrial, and high-humidity environments. With RS485 MODBUS RTU communication and optional RS232, USB, Ethernet, or wireless transmission, the sensor can be seamlessly integrated into automatic weather stations, IoT platforms, telemetry systems, and smart agriculture management solutions.

How It Works

The KH.CQX-6 uses ultrasonic measurement technology to calculate wind speed and wind direction by analyzing the transmission time difference of ultrasonic signals between sensor probes.

Temperature, humidity, and atmospheric pressure are measured through integrated environmental sensing elements, while rainfall is detected using a piezoelectric rainfall measurement module.

This integrated sensing method provides:

• Real-time monitoring of multiple meteorological parameters
• Stable measurement without mechanical moving parts
• Reduced maintenance requirements
• Reliable performance in complex outdoor environments
• Easy integration into IoT-based monitoring networks
