Here's the old, historical text from our ancient cable -  We had a completely custom version of this cable manufactured just for us! We had to buy 50,000 custom resistors in order to have this cable manufactured. No other "Samsung compatible" OTG Y-cable currently available has been manufactured to this specification. You think the cable from Amazon or Newegg will work? Wrong. Ours is the only one that works, so save your money and get it here. Otherwise it won't work. :)

Customers all around the world have said this cable is amazing!

This cable lets you connect your Valarm Pro-equipped Android device to a USB Valarm Compatible Sensor at the same time as charging with a charger.

The Y-cable has 3 ends:

  • Male micro USB end (right-angle connector) plugs into your device
  • Female full size USB end plugs into your sensor (or USB hub) with a USB cable
  • Female micro USB end takes in power (e.g., from the wall, solar panels, car cigarette lighter / accessory charger)

Confirmed, Supported Devices:

  • Galaxy S3 (tested T999, GT-I9300)
  • Galaxy S4 (tested SHG-537)
  • Galaxy Note 2 (tested N7100)
  • Galaxy Note 3 (tested N900A)

* DOES NOT WORK WITH S2, S5, Note 1, Note 4, Tab 2 or Tab 3, nor any Note Tablets e.g. 8.0, Note 10.1, Note 10.1 2014!!! * We have never claimed this cable will work on these devices, and customers who tried anyway have reported that it DOES NOT. *

Note that this cable is intended for remote environmental monitoring with the Valarm Pro app. It requires a power source to work and it may not work with big hard drives.

Cables like this are critical for long-term Valarm remote environmental monitoring deployments such as those done at La Brea tar pits, vineyards / agriculture, and Los Angeles Natural History Museum.
