Just a few of many:  IOD Data Loggers

Presentation to Scripps Technology Forum 15 Dec 2005.
PDF:  Just a few of many: IOD Data Loggers

DL1-Met Environmental Data Logger (2003)

Data logger with MultiMediaCard (MMC) socket and sensor interfaces for Intersema MS5534 Barometric Pressure Sensor, Sensirion SHT-75 Humidity Sensor, two temperature sensors, two anemometers (wind speed and direction), tipping bucket rain gauge, and LI-COR LI-200 Pyranometer.  Logger transmits data over a wireless network via a MaxStream 9XStream Radio Modem.

DL2-Met (2003)

Data logger with MMC socket and sensor interfaces for Paroscientific Digiquartz Barometer, Vaisala HMP-50 Humidity Probe, Eppley Labs Precision Spectral Pyranometer and Precision Infrared Radiometer.

DL3-PSensor (2003)

Data logger with MMC socket and sensor interfaces for Paroscientific Digiquartz Pressure Transducer, Seabird SBE-4 Conductivity Sensor, thermistor, and software uart.

DL4-GP (2005)

Data logger module with MMC/Secure Digital (SD) data storage designed to plug in to Application Specific Interface Modules (ASIM).  Three ASIM modules have been built to interface with the DL4-GP: DL4-IO1-Met, DL4-IO2-GPS-COMM, and DL4-IO3-GPS-COMM.

The DL4-IO1-Met (2006) provides an interface to a suite of meteorological sensors:  wind speed and direction, relative humidity, temperature (3 channels), solar radiation, barometric pressure, precipitation (2 channels), soil/fuel moisture (4 channels).

The DL4-IO2-GPS-COMM (2006) adds three asynchronous serial I/O ports to the DL4-GP through a multiplexed interface to USART1 on the MSP430 microprocessor.  One port is dedicated to a Trimble Lassen IQ 12-channel GPS.  The two other ports are set up for RS-232 serial communication (RX, TX, CTS, RTS).

The DL4-IO3-GPS-COMM (2008) is a follow on to the DL4-IO2.  It adds eight multiplexed asynchronous serial I/O ports to the the DL4-GP.  One port is dedicated to a Trimble Lassen IQ 12-channel GPS, two other ports are set up for RS-232 serial communication (RX, TX, CTS, RTS), and five ports are designed for 3V CMOS serial communication.  This hardware was designed for a project that needed to interface the logger to a Digi XStream 900 MHz radio modem, Judd Engineering Ultrasonic Depth Sensor, several Decagon ECH20-TE and 5TE Soil Moisture Sensors, and a Solinst Levelogger.

A time lapse camera system has been developed using the DL4.  The DL4 was used to take pictures twice a day with a Nikon D2Hs.  It has been deployed for the winter seasons (five months) of 2006-2007 and 2007-2008 in Yosemite National Park.
