Product Overview
The OHTS1070 is an integrated ultrasonic meteorological monitoring device featuring a multi-parameter all-in-one structural design. It supports synchronous acquisition of meteorological elements including wind speed, wind direction, air temperature and humidity, ambient noise, particulate matter concentration (PM2.5/PM10), carbon dioxide concentration, atmospheric pressure, light intensity, optical rainfall, and total solar radiation.
The device utilizes the ultrasonic time-difference method (Time-of-Flight) for wind speed and direction measurement, supporting 360° omnidirectional detection with zero starting wind speed and no mechanical wear. It features an RS485 interface supporting the standard ModBus-RTU communication protocol with a maximum communication distance of 2000m. An optional built-in electronic compass module is available for mobile platforms and installation scenarios without directional references.
The enclosure is constructed from UV-resistant ABS material with a protection rating suitable for long-term outdoor deployment. Critical sensor components utilize industrial-grade devices to ensure measurement stability across wide temperature and humidity ranges.
Features
- Ultrasonic Wind Speed & Direction Measurement: Based on the ultrasonic time-difference principle, with no starting wind speed threshold, supporting a wind speed range of 0 ~ 60 m/s and wind direction range of 0° ~ 359°, featuring no moving mechanical parts
- Multi-Element Integration: Single device integrates temperature/humidity, noise, PM2.5/PM10, CO2, atmospheric pressure, light, rainfall, and solar radiation sensors, reducing deployment complexity
- Electronic Compass Function: Optional built-in electronic compass eliminates installation orientation constraints; horizontal installation enables automatic wind direction reference calibration
- Wide Voltage Power Supply: Supports 10 VDC ~ 30 VDC DC power supply with typical power consumption less than or equal to 1.2W
- Standard Communication Protocol: RS485 interface, ModBus-RTU protocol, default baud rate 4800 bit/s, supporting address configuration and parameter reading
- Environmental Adaptability: Operating temperature range -40°C ~ +80°C (some sensors have narrower applicable ranges), UV-resistant enclosure design
