Description

Dr. Liu brings you the ultimate environmental logger hardware: SDI-Serial shield and dongle (picture 4)! This is SDI-12 and RS232 sensor logging made easy for you! If you are interested in data logging and telemetry in the field or in the home, check out this capable logger shield.

Free Arduino sketch for reading and logging sensor.

USB adapter also available for direct interface with PC/Mac/Linux without Arduino

Picture captions:
1. An assembled shield. Notice some screw terminal blocks are not soldered (until after the picture was taken).
2. An annotated version of the previous picture. This serves as a guide to assembly and connection.
3. An assembled shield with an Arduino xbee shield on top, a phi-panel LCD keypad interface connected to it and two SDI-12 sensors on a stereo splitter.
4. An assembled shield with a Rugged Circuits motor shield and an Arduino wifi shield (below). The wires are mockup of a logger shield that uses two RS232 serial sensors, one motor, and external power and a phi-panel LCD keypad interface. The mockup is actually used in a data logger developed by Dr. Liu for a researcher.

Functions (shield):

  • Connects to SDI-12 sensors like a serial device with the on-board SDI-Serial translator chip. You can connect SDI-12 sensors such as Decagon soil sensors to the shield and use Arduino MEGA’s Serial2 to talk to them directly, no library needed and sample code is included. Just plug the sensor into the stereo plug. This eliminates the guesswork of using others’ library and running into a tree trying to integrate several libraries together and see your project fall apart!
  • Connects to up to 2 RS232 serial sensors. Includes a MAX3232 breakout board so you can talk to two real RS232 devices with +- 12V logic on Arduino MEGA’s Seral1 and Serail3. Not using RS232? No problem, you can still hook up your TTL serial devices with the conveniently grouped screw terminal blocks.
  • A DS1307 real time clock is included on the shield, allowing your logger to acquire time stamps for data logging.
  • Connects your computer to any SDI-12 device. Fancy a PC or Raspberry PI data logger with SDI-12 sensors? An SDI-PC adapter costs over $100 and provide limited functionality. No problem, you don’t even need an Arduino. Just a TTL USB adapter (around $7) will connect the shield directly to a computer’s USB port. Open a serial monitor and type in your SDI-12 commands to explore the sensors, set addresses, and make a logger out of it! 12V power is required to power the sensors through a power barrel or screw terminal block.
  • Connects to 8 analog sensors easily! On-board screw terminals are arranged in 5V, gnd, and analog in patterns, allowing you to connect up to 8 analog sensors with ease. No messy jumper wires that fall off! Analog channel 0 is monitoring battery (Vin) voltage.
    Monitor your battery in a snap! A simple voltage bridge on analog channel 0 allows Arduino to monitor battery (Vin) voltage. No need for a proto board!
  • Use a wifi, ethernet, or other shield on top! The ICSP header is passed through.
  • Dedicated connector for a phi-panel LCD keypad system. This makes your logger so much easier to use if you didn’t already have a professional-looking display/keypad menu display system. Adding a menu system is easy as snap. Sample code is provided. What you send (through serial to phi-panel) is what you see (menu on phi-panel). No library is needed.

  • Other parts needed:
    Arduino MEGA 2560 Rev. 3 is needed for a fully functional logger.
    FTDI USB TTL adapter is needed to interface this shield with a PC or Raspberry Pi.

    Resources used on Arduino MEGA 2560:
    Serial1 is connected to MAX3232 for RS232 devices. You can use it if you’re not using an RS232 device on this port. In this case, don’t attach the MAX3232 breakout board.
    Serial1 is connected to on-board SDI-Serial translator. You can’t use this port for other activities unless you don’t intend to use SDI-12 sensors and are short of serial ports.
    Serial3 is connected to MAX3232 for RS232 devices. You can use it if you’re not using an RS232 device on this port. In this case, don’t attach the MAX3232 breakout board.
    I2C is connected to the DS1307 RTC. More I2C devices may be connected.
    Digital pin 2 and Analog pin A15 are connected to phi-panel connector. If you don’t use a phi-panel, you may use these pins freely.
    Analog pin A0 monitors battery/Vin voltage.

    Functions (dongle):
  • Connects to SDI-12 sensors like a serial device to Arduino with the on-board SDI-Serial translator chip. Audio jack and screw terminal blocks
  • Power barrel and screw terminal block
  • Future firmware upgrade will allow:
  • Battery monitor
  • 4 analog sensors

  • Other parts needed:
    FTDI USB TTL adapter for PC or Raspberry Pi
