• Wind speed
• Wind direction

Typical applications

With the most lightweight and all-in-one meteorological sensor, our Sniffer4D V2 ultrasonic wind speed and direction sensing module can be easily installed on DJI M300 RTK/M210 RTK and monitor the meteorological parameters (temperature, humidity, atmospheric pressure, wind speed, and wind direction) in real-time. Integrated with Sniffer4D V2, the system can precisely acquire the meteorological information by calculating the back-and-firth time difference of the ultrasonic waves in 3D dimension.

Our Ultrasonic Wind Speed and Direction Sensing Module allows the Sniffer4D to simultaneously monitor the target gases and the meteorological parameter in applications like Ambient Air Monitoring, Meteorological Monitoring, HAZMAT Response, providing intuitive and insightful information for decision-makers.

Real-time Data Transmission

Sniffer4D V2 supports transmitting real-time data from our ultrasonic wind speed and direction sensing module. After being processed by our proprietary algorithms, the meteorological parameters will be shown in DJI pilot app and Sniffer4D mapper. In this case, the system is rather user-friendly since our data provides real-time references and does not require post-processing work. Meanwhile, all the data will be automatically stored in Sniffer4D V2's onboard SD card for after-mission analysis.

Built-in Motion Compensation Algorithms
