Our thanks to everyone who has sent us details of their instrument and helped us compile this list. Notes: ====== The "typical message string" gives an example of the sequence of characters sent by the instrument when it transmits data. Where the instrument requires a command to transmit data, this is shown below as the "prompt string".
represents a carriage return. represents a line feed. The "Windmill parse string" gives an example of how you might set up Windmill to extract data from the instrument. We haven't included this for instruments sending many items of data in one message. For more details of extracting data see https://www.windmill.co.uk/parse.html * Furuno Sonar Typical message string = $SDDBT,22.3,f,6.8,M,3.7,F Windmill parse string = \S"SDDBT"\S"f,"\E"," More details at https://www.windmill.co.uk/seafloormapping.html * MSI 3360 Scales Typical message string = 2001 LB GROSS Windmill parse string = \E4 * OBD - on board diagnostics Typical message string = 41 0D 37 Windmill parse string = \I06\E02 More details at https://www.windmill.co.uk/obd.html * Orbital Science OBIU with Motorola GPS Typical message string = Gps:@ 1/13/1999 22:04:02 Gps:Sec Latitude Longitude Sp Hed V T U Dop St Gps:02 +455248866 -1226843925 0 64 7 5 3 25 14 Gps:03 +455248875 -1226843911 0 63 7 5 3 25 14 Gps:04 +455248875 -1226843911 0 69 7 5 3 25 14 Gps:05 +455248888 -1226843994 0 59 7 5 3 25 14 Gps: Diff Corr Msg Sent To Gps Gps:06 +455248894 -1226843880 0 66 7 5 3 25 14 Gps:07 +455248902 -1226843875 0 55 7 5 3 25 14 Gps:Dgps Ack Rxed Gps:08 +455248913 -1226843863 1 57 7 5 4 22 10 Gps:09 +455248908 -1226843891 1 58 7 5 4 22 10 More details at https://www.windmill.co.uk/serial_driver.html#gps * Parallax BASIC Stamp Message string depends on your Stamp program.

Details are at https://www.windmill.co.uk/monitor117.html and https://www.windmill.co.uk/monitor118.html The previous examples showed how to attach the measurement spreadsheet, how to include data in the body of the message and how to set the e-mail to be from any address you pleased. This month: how to attach any file to the e-mail. You can download an example spreadsheet with the necessary macros from https://www.windmill.co.uk/excel/sendfile.xls Our thanks again to Brian Yeager of SCE & G for suggesting this addition. Function InsertFile(ByVal sfile As String) As String 'This function supports attaching a file to an ‘outgoing CDO e-mail.

Robot fish may track whales or pollution In the world of underwater robots, new Robofish are a team of pioneers. While most ocean robots require periodic communication with scientist or satellite intermediaries to share information, these can work cooperatively communicating only with each other, wirelessly, underwater. Messages were sent between the robots using low-frequency sonar pulses, or pressure waves.

Engineers have identified a biological mechanism in the mayflies that could enable sensors in stagnant environments to make air or water flow past them so they can detect harmful substances.

Because each Bluetooth device has its own distinct digital signature, its travel time can be tracked by detectors installed at intersections or along highways and other locations.

Developed by engineers at the University of Leeds, the sensor device gathers data on air temperature, humidity, air pressure, light, and soil moisture and temperature – information crucial to making key agricultural decisions about planting, fertilisation, irrigation, pest and disease control and harvesting.

The robot can navigate indoors where GPS navigation does not work, using sonar infrared lasers.
