The dust particles concentration is measured using the laser scattering principle.

The transmitter is maintenance-free and has fast response, high sensitivity and an excellent stability.

The PM sensor can be operated in two ways:

• Continuous operating mode: the sensor is always active and measurements are continuously taken. In this mode at least 10,000 hours of PM sensor life are guaranteed.
• Discontinuous operating mode (default): the sensor is activated at regular intervals, when measurements has to be taken. This mode increases the PM sensor life.

On request, an optional CO₂ sensor can be integrated in the trasmitter.

The transmitter can be supplied with up to 2 optional configurable 4…20 mA, 0…5 V or 0…10 V analog outputs.

• Wind speed
• Wind direction
• Temperature
• Relative Humidity
• Barometric Pressure
• Rainfall

HDMCS-100 is a self-supporting system complete with solar panel, back up battery and built in GSM. This makes the AWS completly independent from any external power as well as from any local structure.

Easy to use: as soon as set up the Meteo Compact Station starts working by sending all measured data to your FTP server or to the Senseca Cloud.

The stable mechanical design alongside the ultrasonic sensor with no moving parts makes the weather station completely maintenance free.

Cables with connectors, solar panel, back up battery, tripod and logger with GSM communication are all included in the set.

For option with solar radiation measurement see HDMCS-200.

• Wind speed and direction, U-V Cartesian components of wind speed
• Wind Gust – Measurement available only with MODBUS-RTU and SDI-12 protocols
• Relative Humidity and Temperature (optional),
• Global Solar Radiation (optional)
• Barometric pressure (optional)
• Rainfall (optional)

The “Rainfall” and “Global solar radiation” options are alternatives (they can not be both present in the same instrument).

All models are equipped with a magnetic compass.

The avarage of wind speed and direction over a period configurable up to 10 mins is calculated.

RS232, RS485, RS422 and SDI-12 serial interfaces are available with NMEA, MODBUS-RTU and SDI-12 communication protocols. All versions have two analog outputs, both for wind speed and for direction, factory configurable among 4÷20mA (standard), 0÷1V, 0÷5V, 0÷10V (to be specified when ordering).

Advantages:

• The absence of moving parts minimizes maintenance;
• High sensitivity for detecting very low speeds, which are not detectable by traditional methods;
• The low power of the instrument allows installation in remote sites, with power from solar panel and battery;
• The heating option ‘R’ prevents the accumulation of snow and ice from forming, allowing accurate measurements in all environmental conditions;
• Fast and easy installation, alignment facilitated by built-in compass;
• The available measurement options join together in one single, compact and lightweight instrument, the main variables of interest in weather stations;
• MODBUS-RTU output allows instrument networking.
