Overview
Enviro Testers’s compact micro ultrasonic 5-in-1 weather sensor is designed to monitor wind speed, wind direction, temperature, humidity, and air pressure on small aircraft and unmanned platforms. Its ultrasonic resonance technology enables precise measurement in low-altitude environments. The unit’s compact structure and strong resistance to electromagnetic interference support stable performance across demanding outdoor conditions.
Features
- Ultra-light structure at 0.14 lb (65 g) with a compact 1.81 in (46 mm) diameter
- High resistance to electromagnetic interference with water and dust protection
- Operates at altitudes up to 13,123 ft (4,000 m) and in temperatures from -40 °F to 158 °F (-40 °C to 70 °C)
- Low-power internal components capable of measuring wind speeds up to 134.22 mph (60 m/s)
- Suitable for unmanned aircraft, flight control platforms, and airborne environmental monitoring
- Supports both top-mounted and inverted installation configurations
