The HD33M.2 data logger has an integrated GSM/GPRS module. It has 5 inputs: easy to use for monitoring (and/or) temperature, humidity, solar radiation, rainfall quantity, wind speed and direction (with cup-anemometer). Optional atmospheric pressure can be integrated in the unit. The instrument can simply be integrated with any FTP or Cloud solution.

Data logger:

• Datalogging of temperature, relative humidity, dew point temperature, atmospheric pressure, solar radiation, rainfall amount, wind speed and direction
• Available in two versions: with input for standard RS485 MODBUS-RTU sensors or with inputs for dedicated Senseca sensors
• GSM/GPRS module for remote monitoring
• Data sending via email, FTP and to an HTTP server (e.g. Senseca Cloud)
• PC software for configuration, monitoring and downloading of data to a database
• Software option available for compliance with FDA 21 CFR part 11 recommendations
• Alarm notification via e-mail and SMS when configurable measurement thresholds are exceeded
• IP 67 waterproof housing
• Optional custom LCD display (HD33LM.2)
• Can be powered by mains or photovoltaic panel (with optional external power supply unit)
• Atmospheric pressure option (HD33M4b.2 or HD33LM4b.2)

Various outputs are available:

• RS485 with Modbus-RTU or proprietary ASCII protocol
• SDI-12
• Voltage-free pulse contact output

The rain gauge is able to provide the total rainfall, the partial rainfall (from the last reset command or from the last reading command), the average rainfall rate in the last minute and in the last hour. The measured rainfall is regularly saved into a non-volatile memory, which retains the information even in case of power failure.

The automatic discharge of the rainfall collected allows using a compact and lightweight structure for the installation of the rain gauge.

So as to ensure accurate measurement even with low temperature climatic conditions, a version with heating which is automatically activated below +4 °C has been developed (HD2016R) so that snow deposits and ice formations are prevented.

This logger has multiple inputs/outputs:

• 4 analog independently configurable inputs
• 2 voltage-free counting contact inputs
• SDI-12 “Master” port compatible with version 1.3.
• RS485 port Modbus-RTU configurable as “Master” or “Slave”.
• Ethernet MODBUS TCP/IP (optional as HD33MT.4/E or HD33LMT.4/E).
• 2 voltage-free contact alarm outputs.

Optionally, on request, an internal atmospheric pressure sensor can be added to the logger. As the electronic circuits for this are already integrated, this will not influence the number of free available inputs .

The modem will step down (from 4G to 3G to 2G) when a certain network is not available.
Standard supplied without display, ordering code with display HD33LMT.4

Depending on the sensors connected, simultaneous monitoring of: temperature, humidity, dew point, atmospheric pressure, solar radiation, amount of rain, wind speed and direction,

Available versions:

• HD2005.20 – Max. height 225 cm.
• HD2005.20.1 – Max. height 335 cm.

It can be fixed on a plane with screws or with stakes on the ground.

To ensure accurate measurements even with low temperature climatic conditions or during and after precipitations of snow, a version with heating system (HD2015R), automatically activated around +4 °C, has been developed to prevent snow deposits and ice formations.

The quantity of rainfall measured is based on the count of the number of times the bucket is emptied: the reed contacts, normally closed, open at the moment of the rotation between one bucket’s section and the other. The number of impulses can be detected and recorded by a data logger such as the HD2013-DB or by a pulse counter. But it is also possible to communicate directly the results through one of our dataloggers of the HD33 series. The built-in 4G/3G/GPRS modem makes it easy to upload the data directly to one of our cloud applications or to your own secured server.

When ordering, the rain gauge is completely setup to be used. Easy to install, adjustable feet and leveling device integrated. Bird spikes and accesories for raised mounting available.

A removable filter for periodic cleaning and maintenance is inserted in the water collector cone so as to prevent leaves or other elements blocking the end of the hole.

• 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.
