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.

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 They are a new range of data-loggers which have superceded the older LX series.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.

The new logger offers a host of features such as:
Memory for 500K readings
(2MB) in Flash memory
Transparent mode via RS232 communications
to allow direct access to each sensor.
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.

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.
DM4 Memory Module:

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.
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.
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.
Resolution: Monibus 16 bit (1 part in 65,500)
Embedded software provides ASCII output. The logger will communicate with any type of PC that uses a communications programme.
Menus: Pre-programmed, single keystroke selectable
menus for parameter changes.
Down-loading: One touch or custom down-loading available.
