Yocto-WatchdogDC

  

This device is an USB-controlled watchdog timer. When installed across a DC power cable, it can cut and restore the power whenever the control application fails to contact it.

The typical application is to power-cycle a crashed computer. As long the control application running on the the computer contacts the device on a regular basis, the power stays on. If, for some reason, the application stops to contact the device, the power will be cut for a short time. The will cause the computer to reboot.

The integration of this watchdog into existing solutions is easy, thanks to the fact that it does not require any device driver. The watchdog timer can be reset either using a command line, or using a simple function call to Yoctopuce library. The Yoctopuce library is available in for most programming languages, in source code form.

This device can also be used as a cheap solid-state relay. Please note that this device is not isolated: the output and the USB share the same ground.

This device can be connected directly to an Ethernet network using a YoctoHub-Ethernet, to a WiFi network using a YoctoHub-Wireless-g, it can even be connected to a GSM network thanks to the YoctoHub-GSM.
