µSmart Loggers - SL Series (Monitor Sensors)

The Monitor µSmart loggers are designed for use with the Monitor environmental sensors, using the proprietary "Monibus" connections.
For other sensors, converters are available to convert voltage, current & frequency to Monibus for input to the logger.
See end of this page, click here.

The environmental sensors, along with any converters, can be "daisy-chained" on one 3-core cable leading to the logger.
For the non-technical user, the "Plug and Play" capability of Monitor sensors and Monitor data loggers provides a simple but powerful system that is extremely user-friendly.
     More about the various sensors: click here
To the researcher, the system still offers all the in-built simplicity while also allowing full access to all the variable parameters to customise the data collection criteria.

In Weather Stations, the Data Loggers are normally supplied with the LCD screen.

These loggers operate with the µSmart series of sensors and offer true plug and play capability. They are a new range of data-loggers which have superceded the older LX series.

The SL5 can accept up to 200 inputs and has 8 input connectors.

Input type: Monibus, a 0 & 5V TTL level serial data protocol

Voltage, Current, Frequency, Counter, Resistive inputs can be converted to Monibus for input to the logger - see end of this page .

They can be configured to suit a wide range of uses, e.g., monitoring water quality, wind characteristics, soil conditions, meteorological conditions and evaporation applications. Systems can interface to PLCs and can provide control or alert outputs.

The µSmart Loggers have Monibus Sensor connectors (Monibus: click here). On the SL5, up to 200 sensors can be connected. Sensors with Monibus outputs can be paralled together with splitters.

Attach new sensors to the logger, and then instruct the logger to find the new sensors. Any new sensor is automatically interrogated and the sensor's profile is down loaded into logger memory. This is then used as the basis of a logging regime, and in the absence of input by the operator, will set up a logging regime that is suitable for the particular sensor. Should the operator need to change the logging parameters the embedded software program offers a range of setup options.

Stored data can be accessed on site with IBM compatible notebook computers, or remotely via modems, radio telemetry, etc. No special software is needed.

There are many programming options built-in... please ask about special requirements. For example, the logger can be set to log data only when an input exceeds a preset threshold.

Processor Speed: up to 33Mhz
Memory: Flash Ram 512KB to 4MB

The new logger offers a host of features such as:

Memory for 500K readings (2MB) in Flash memory
See below for optional removable Memory Module.
Real time clock

Transparent mode via RS232 communications to allow direct access to each sensor.
Battery voltage monitoring is provided.

The LCD display shows one reading, scroll to see all channels.

Data Output: RS-232 or optionally Monibus output, RS422, RS485. (Monibus output will permit three wire communication over distances in excess of 4 kilometres). This allows several nodes to be setup over a wide area. A Monibus to RS232 converter may be used next to the computer.

No additional software is required; use a terminal program such as Windows Terminal or HyperTerminal (in Windows, under Accessories... Communications) to operate the logger.

Built-in battery with battery voltage monitor supports the logger and attached sensors for weeks or months depending on the reading rate of the logger and the number of sensors. A mains adaptor battery charger is included, otherwise a solar panel can be used.
Battery saving programming features.

Removable memory module DM1 for use with DS1 docking station.
GPS interface
3 High speed counter or Voltage output combination.
Low speed counters.
Available programmed in most languages

An LCD display (two line x 16 characters) is built into the logger as standard.

µSmart Logger SL5 Data Logger has 8 input connectors and can accept up to 200 inputs,
has 2MB flash memory for 500K readings, with battery, cable, and embedded software.
Battery charger is included in non-solar powered systems.
Note: Two or more sensors can be daisy chained together and connected to one input on the logger.

Also included:
CM2 Interface Cable, RS232 - DB9, 2 mtr cable, for connection to computer.
IB14 Interface Bus Bar - 14 Channel
CH6 240/12v 1 amp power supply

Additional memory options:     -4: with 4MB (>960K readings):
A mains adaptor battery charger is included in non-solar-panel powered systems.

LCD Displays (optional)

A two line x 16 characters display is built into the logger.

Display Button press: backlight comes on, time and battery voltage is shown, then it shows the first two channels for 3 seconds, then proceeds to the next, and so on.
Holding the display button down makes it proceed more quickly.

The LCD Display can be built into separate case  
The display case would be connected to the data logger by its own cable.
The following need to be powered. Power Supply is not included in price.
LCD1: Single channel LCD real time display (one two line x 16 char display)
LCD2: Dual channel LCD real time display (two two line x 16 char display)
LCD3: Three channel LCD real time display (three two line x 16 char display)
LCD4: Four channel LCD real time display (four two line x 16 char display)

They use the Monibus output from the sensors.

The above displays may be connected to a modem using the
SI8 Converter (incl 500mA power supply for sensors)
An extra connector can be fitted to the LCD Display case for this purpose, at no extra charge.

Memory Modules, removable

DM4 Memory Module:   holds 500K readings, for µSmart Loggers: plugs into DB9 connector on front of logger.
Can be unplugged, and read with DS1 Docking Station connected to PC RS232 port.

Stored data is retrieved via the RS232 interface using Windows terminal, other terminal programs such as Procomm or Monitor Sensors proprietary software.


µSmart ML Logger

    Data: click here

The MLx data logger has been designed as a low cost but effective data logger and uses the same logging engine as the PLx and SLx data logger series.

The MLx is application specific, offering options such as temperature, event, humidity or a combination of these and other types of inputs. The data logger has the same internal operating capabilities and features as the other versions such as full logging control, embedded software and large memory, but cannot be upgraded at a later stage unlike the SL and PL versions of the data logger.


µSmart PL Logger

for event counting applications such as Pluviometers (rain gauges), etc
or applications where an additional sensor is required to be logged in conjunction with the primary device.

The PL Data Logger is available in four versions:
PL1 has a single counter input for sensors which need counters, such as tipping bucket rain gauges,
PL2 has a single counter and two additional Monibus channels for µSmart sensors,
            with "Plug and Play" capability as is found in the SL series of Loggers.

Designed for use inside Pluviometers (rain gauges) to make tham smart, or with proximity switches, contact closures or digital input events, counting type applications, and where a small logger is required. It offers a simple but powerful operating system that is extremely user-friendly and suitable for both the general and scientific user.

The PL loggers offer a minimum logging period of 1 second in standard form, but can count and record multiple tips during the one-second period. Embedded software that will operate with any PC with an on-board communications programme, or dumb terminal.

The Logger is provided with embedded software that will operate with any PC running a communications programme, or Dumb Terminal.
To activate the "Plug and Play" feature, simply attach the new sensors to the logger and then instruct the unit to search for sensors.

Interface units are available to convert other Manufacturer's sensors for use with the PL Series.
Using the SI-1 Data converter, any instrument can be made compatible with the Logger and at the same time upgrade the sensor or instrument with all the capability of the µSmart range.

Power: 8-40 volts unregulated DC.

Control output: 1. Additional outputs can be provided.
Sampling rate: Minimum period 1 second
Maximum period 24 hours
Each sensor's sampling rate can be set individually.
