Weather Stations - Monitor Sensors
automatic, solar powered,
Sensors' new generation of environmental sensors are designed with reliability,
low power requirements and accuracy with added sophistication as follows.
They can be used with a weather station or separately.
µSmart sensor incorporates a microprocessor providing
linearised and standardised outputs, 16 bit resolution (1 part in 65,000) and
output signals: analog, ASCII data output/input via serial interface, pulse, control & alarm outputs.
Each unit is provided with a multi-point calibration curve for maximum accuracy across the range.
All µSmart sensors of
a given type have the same specifications and calibration.
This eliminates any need to reconfigure the system when a sensor is changed.
The on-board microprocessor ensures identical performance characteristics.
With many other systems, changeover of a sensor means either recalibration of the system or resetting of parameters in the data logger.
For list of sensors, see below: click here
sensor can now be a stand alone instrument that will monitor, log and control
an operation within predetermined limits.
There is no longer any need to have ancillary equipment such as a data logger to store information or carry out control functions.
Sensors have their own embedded menu system so that
various sensor parameters can be set using a computer in terminal mode,
e.g. sensor characteristics, thresholds, auto-zero, verbosity (e.g. units text on/off), and other changable parameters.
These new instruments provide cost effective monitoring solutions for markets from the agricultural and environmental sector to the process and control industry.
See below for list of sensors: click here
Sensor outputs can be
analog V or I out (not both), frequency, or Monibus (0-5v TTL serial data, see description below).
When used in the weather stations, the Monibus output is used to connect the sensors to the data logger.
The Monibus output is easily converted to RS232
for connection to computers or telemetry equipment (See SI8 and SI-8 below).
Sensors can be made with two control
These are called Goldline Sensors (see further down).
The analog output (voltage or current loop option) is continuous.
The digital ASCII character output updates every second.
Gold Line Sensors also have...
3-wire cable provides:
One output only: Monibus serial ASCII output (used in the weather
stations, see description below)
4-wire cable provides:
First output: Monibus
Serial ASCII output (see below) (yellow or orange wire)
4-20mA Current Loop output
(instead of Voltage Output) can be fitted for additional cost.
Monibus: Serial ASCII output:
0-5v TTL serial data bus.
The host polls each sensor separately for its readings, or each sensor can poll
the next after sending its own data.
output: Voltage 0-1V, or any range up to 4V
Frequency output: 2-10Hz (0-5v TTL)
The µSmart sensors may also be used with Datataker data loggers (opens new tab or window).

SI8 Converter: Monibus
to RS232 Serial Interface Unit: for interface to computer,
with power supply to run sensors. Data: click here See notes about command timing below.
It operates at 1200bps only.
It consists of a small box 72x43x27mm with 3 cables coming out, 2 at one end, the 3rd at the other end.. The cables are 0.65m long.
The 3 cables: RS232 with DB9F connector; Power (+ & , 6-28 volts unregulated DC);
Monibus triple cable (+, , & serial data)
The SI8 provides power to the sensors attached to it. Large picture of SI8
The SI8 gets this power either from
1) the host computer's RS232 port or
2) a supplied mains adaptor, or
3) 6 - 24V DC unregulated. This could be an external battery.
The SI8 itself uses about 7mA. Add to this the current drawn by the attached sensors.
The RS232 port on a 486 computer can supply 3 or 4 mA. (1 or 2 sensors)
The RS232 port on a Pentium computer can supply 8 to 10mA. (8 or 10 sensors)
Sensor cable length can be up to 4000m.
SI-8 Converter: as above,
except is powered from the computer's RS232 port:
A pair of wires are provided for connection of external power supply should the serial port's supply be insufficient. (5V to 20VDC max)
The RS232 port on a 486 computer can supply 3 or 4mA (1 or 2 sensors)
The RS232 port on a Pentium computer can supply 8 to 10mA. (8 or 10 sensors).
A pair of wires comes out of the unit which can be connected to a power source (6 to 24VDC) if required.
Sensor cable length can be up to 250m.
DB9F (25-pin female). SI-8:
Sensor Power Requirements
Water level 7mA, pH 5mA, Turbidity 10 to 16V DC at 15mA (45mA for Model 195 when wiping)
Soil moisture 4mA, Barometric Pressure up to 5mA
Wind Direction 2 mA,
Other sensors use up to 2 mA.
about timing of commands:
1) There is no dead time on the Monibus as such. The SI8 itself has no intelligence or storage facility. It passes the messages with negligible delay (a few microseconds). The sensors do have a delay in responding and this is necessary in order to make sure they have received the full command. There is no "end of command" character.
The end of command is indicated by a pause in transmission of approx two bytes duration. At 1200 baud this corresponds to a time of 16 to 20 milli seconds. After this time the sensor decodes the command and sends a reply if necessary.
2) In practice this reply will begin between 22 and 27 milliseconds after the last byte of the command has been sent.
3) The way to make sure that the sensors
are ready to receive a new command is to wait for the Monibus to be idle for at
least 30 milliseconds. This includes waiting for any responding sensor to finish
its message and then wait the additional 30 milliseconds.
NOTE: The sensors do not know the origin of any command on the Monibus.
They will respond to a command from another sensor as well as from the PC or a logger. This is what happens when the sensors are put in daisy chain mode. For example, you could put the TA1 and HU1 in daisy mode. Then you would only need to send the address of the TA1 and both sensors would reply in sequence. You can even pre-determine if this reply is to be on the same line or on three lines.
To use daisy chain mode in its simplest form you will need to have the sensors on sequencial addresses e.g. 2,3,4.
You can turn on daisy chain mode through the sensors' setup menus BUT as soon as power is broken, daisy chain mode will be switched off. If you want PERMANENT daisy chain mode you need to send a special command (ask for details).
4) The sensors can not store commands. They can only handle one command at a time. A string of commands will normally be ignored by all sensors. A gap in transmission of 30 milliseconds will cause the sensors to start to look for a new valid command.
Current Loop Outputs:
4-20mA current loop output can be fitted for additional cost.
Power voltage required for this is 13.6VDC to 28VDC.
Output cable required is 3-core: Power (13.6VDC to 28VDC), 4-20mA current output, and Ground.
The following voltage and pulse converters, V01, V02, etc, are similar to µSmart Sensors, as described near the top of this document, giving the µSmart outputs (Monibus, voltage , frequency). They can make many kinds of instruments and sensors compatible with the Monibus sensors and with Monitor Sensors data loggers.

Software for downloading the data from
The SmartLogger software is a basic program to help with downloading data from Monitor SmartLoggers,
graphing it, or saving it to an Excel file.
It also works through a GSM or dial-up modem connection.
Using a Terminal program
The µSmart data loggers, and the sensors (without a data logger), can be downloaded and controlled using a terminal program
(e.g. Windows HyperTerminal included with Windows 95, 98, XP, etc),
for setting up, unloading data in readable text format and storing to disk.
The user can access a sensor using the Windows HyperTerminal program. Screen shot: click here
Download our terminal program for Windows PC: Mterm.exe
new Windows Software searches for and finds sensors automatically,
either when connected to a Monitor Sensors data logger, or when connected to the serial port via SI8 (Monibus to RS232 Converter).
It logs data from sensors to disk in CSV text format which can be readily imported into spreadsheets or
data can be linked by DDE directly into applications such as a spreadsheet.
Trend plotting, etc, can then be done in the spreadsheet.
It also displays the most recent readings on-screen, including "dial" and "meter" readouts.
Can generate an SMS message on an alarm condition. (E-mail could be added).
Many other useful features.

Monitor Sensors can supply Ethernet
interfaces for the Monitor SmartLoggers,
and server software that can automatically retrieve the current readings and historical data from the logger.
The retrieved data can be optionally merged into a user supplied web page template
and automatically uploaded to a web server by ftp.
Two templates are provided - a current readings table and a web graph page.
The program includes a terminal interface that allows the logger to be customised and the data stored by the logger to be retrieved.
A running log of the program operation is saved regularly to help the user resolve any upload problems.

We also have been working on a GPRS
interface to our sensors and loggers.
This allows a group of sensors or logger to connect to server software over the internet using a GSM/GPRS modem.
This allows realtime data at a cost of about 10c a packet.
