The CLIMA SENSOR US is a weather-measuring instrument used for the acquisition of meteorological parameters. Depending on the development level, the device supplies measured data for: Wind velocity, wind direction, the wind direction of gust, temperature, relative humidity, air pressure, brightness (North-East-South-West) [lux], the direction of brightness, precipitation status, precipitation intensity, precipitation total, type of precipitation (Synop code), GPS data (date, time of day, degree of longitude, degree of latitude, the position of the sun a level, etc.

Wind speed and wind direction are determined by acquiring the 2-dimensional horizontal components of ultrasonic measurement paths positioned at right angles to each other. The speed of sound can also be used to calculate and output the acoustic virtual temperature. The ultrasonic measurement principle allows for inertia-free measurement of gusts and peak values.

Air temperature and relative humidity are measured via a built-in precision combination sensor, which is equipped with a weather and radiation shield. Barometric air pressure is measured with a MEMs (micro-electro-mechanical system) sensor based on piezo-resistive technology.

Measurements of the precipitation intensity are contactless, using a signal reflected by a Doppler radar. When calculating, the intensity captured for the last minute is extrapolated to output for one hour. The type of precipitation can be roughly determined from the measured values of rainfall speed, intensity, temperature, and humidity.

Brightness is captured by four photo sensors with a spectral sensitivity curve. The direction of the light source is calculated using the prevailing intensity conditions. The logarithmic intensity characteristic of the photo sensors allows light intensities to be measured and output in a wide range between 1 and 150,000 lux.

A GPS receiver is used for the determination of position and as a real-time source; additionally, it is used to calculate the current position of the sun. Position, time, and position of the sun are provided via the RS485 and 422 interfaces.

A RS485/422 interface is available for serial communication. It can be operated in full-duplex or half-duplex mode. Predefined data telegrams are available for outputting measured values (e.g., VD, VDT, NMEA, etc.). A Modbus RTU protocol is additionally implemented for extended standard communication. The device can be switched to Modbus RTU mode with the relevant command. The CLIMA SENSOR US is equipped with a built-in heating system.
