Compact all-in-one weather sensor integrating ultrasonic wind measurement, air temperature, relative humidity, and barometric pressure in a single body. Reliable, low-maintenance, and IP65-protected, ideal for smart buildings, environmental monitoring, and smart city applications.
The DNB200 is a professional-grade compact weather sensor that combines multiple measurements in one device. Equipped with an ultrasonic wind sensor, multi-element temperature sensor, fast-response capacitive humidity sensor, and state-of-the-art barometric pressure sensor, it ensures reliable, long-term performance in industrial and environmental monitoring applications.
Applications
DNB200 is suitable for a wide range of applications including smart buildings, coastal area monitoring, smart grids, and smart cities. With no moving parts, compact size, and low visual impact, it is particularly effective where reliability, durability, and easy installation are required.
Design and Installation
The sensor is built with a robust plastic housing and protected to IP65 standards. It connects via RS485 with Modbus-RTU protocol for easy integration into third-party and LSI LASTEM data loggers. Quick mounting on standard poles (Ø 35...50 mm) makes installation straightforward, while low power consumption ensures cost-efficient operation.
