usense USB Sensors

Supports the Vernier GoTemp and the TEMPer1 USB temperature sensors via libusb.

Vernier GoTemp!

The Vernier GoTemp! looks like this:


  • Expensive
  • Requires calibration
  • Probe is not salt-water tolerant.
  • When potted in epoxy, probe lasted 12 months


The TEMPer1 and TEMPerNTC devices look like this:

Supports the TEMPer, TEMPer1 (with external probe), and TEMPerNTC (with external probe)


  • Cheap
  • Factory calibrated
  • Probe on TEMPer1 is not salt-water tolerant over a long period
  • Internal hardware of the TEMPer1 has changed, from a USB Serial to a USB HID device

After about 3-4 months, salt water will get between the wire and the epoxy, and reach the integrated circuit inside. I do not recommend this device as-is for salt-water immersion.

However, this probe works fine for measuring tank temperature if you tape it to the outside of the tank, then tape some insulation over that.
