I'm low on stock. I'll be recounting my stock and making new batches ready to ship late August. In the meantime, the qty stays 0. PC Win 7/10/Mac/Linux/Raspberry PI/Beagle Bone Black compatible

This product is an extension board for the following product(s) and only works when you have one of these products.

• SDI-12 USB adapter
• SDI-12 Data Logger (will be posted soon!)

This extension board with SDI-12 USB adapter gives you 4 SDI-12 terminals to easily add more SDI-12 sensors to your existing project.

SDI-12 sensors are widely used in environmental monitoring including soil, streams, plants etc. On the other hand, data loggers designed for SDI-12 sensors are usually expensive and proprietary, making it harder to monitor and study soils and streams on a budget. This SDI-12 USB adapter makes it possible to directly interface SDI-12, Analog sensors, and GPS with a PC/Mac/Linux/RPI/BBB, on a budget. I have built numerous SDI-12 sensor data loggers. This is my latest design that is very easy to use. It also comes with free and open-source data logger program (Python script) for all operating systems. A section on SDI-12 sensors will guide you through it. A $5 Raspberry PI Zero is more than sufficient to log data.

Included features:

• 4 SDI-12 sensor terminals
• 8-pin male header to be soldered to your SDI-12 USB adapter
• Pass-through extension board header will accept future extension boards of various types
• 4 M3 standoffs, 8 washers (2 on each standoff), 4 screws, and 4 nuts for securing the extension board

You may stack several of these and other extension boards to a single SDI-12 USB adapter. If you order this item with SDI-12 USB adapter(s), I will solder the 8-pin header to the SDI-12 USB adapter(s) in your order.
