Yocto-Knob Ethernet

   

Combine a Yocto-Knob with a YoctoHub-Ethernet to get an autonomous appliance with built-in network connectivity:

Yocto-Knob

YoctoHub-Ethernet

The Yocto-Knob device provides easy reading of 5 input buttons, contacts, switches or potentiometers (knobs). It is a kind of USB analog-to-digital converter (adc). It can also be used to read any analog resistive sensor, such as photodiodes.

On the device, 5 tiny LEDs constantly show the value of the 5 inputs, and 5 micro-switches connected in parallel to the inputs simplify the testing of your project.

The YoctoHub-Ethernet is a Fast-Ethernet module that can host three Yoctopuce modules to access them remotely. It can be powered either by a USB Micro-B cable, or directly from the Ethernet cable (PoE compatible with 802.3af standard).

Three Yoctopuce modules can be connected directly, one of which can be fixed directly on the YoctoHub-Ethernet and connected using a Board2Board-127 connector. More devices can be connected thanks to the YoctoHub-Shield extension. The YoctoHub-Ethernet can power Yoctopuce devices up to 2A.

Android™ app Valarm Pro v1.1.0 includes support for the incredibly fun and useful Yocto-Knob sensor! You can use these sensors/switches/dials to trigger alerts and/or record the conditions of a variety of cool stuff you might need to monitor. All without any programming: just configure Valarm on the host Android and away you go. Here are some ideas:

- Monitor any equipment with LED status lamps
- Monitor and alert you to the level of fluid (water) in a reservoir or tank (either in fifths, or with e-tape)
- Monitor burglar-alarm switches on doors and windows
- Alert you of flooding/presence of water on the floor or in a tub
- The lights go out unexpectedly in your indoor hydroponic garden
- Measure how far open a door or flap is (this is how the MAF sensor in some cars works)
- How many times your dog goes in and out the pet door every day
- Alert you when your laptop comes and goes from its stand, how much milk is left in the fridge, or anything else that might exert pressure/weight.
- Many, many more possibilities!

See http://valarm.net/yoctopuce for more information.

Cheers,
Edward.

When the Yocto-Knob device is connected with the samsung tab two is not implemented. These instructions are for your attend.
Please give your kind attention as soon as possible.



Thank You.

Can I use the Yocto-Knob device to measure the low voltage e.g. from a Lipo cell that powers a RaspberryPi?
Best regards,
Nic

@nic: No, the Yocto-Knob is meant to interact with resistive devices only (switches, potentiometers, photo-transistors etc...). Injecting current in the Yocto-Knob inputs is very likely to fry it.

i want to use it with potentiometer. but i don't know how can i connect it with potentiometer. i know that potentiometer have 3 lines(Volt, ground, output). which line is appropriate to each yocto-knob's channel?
Can you tell me by the picture?

@dudwo5929: use the potentiometer center contact with any of two other ones, as described in the user manual:

Don't worry, even if you do it wrong, you won't break anything.

Yoctopuce, get your stuff connected.
