If you are looking for some inspiration for your next project you might want to have a look at the NetSensor kit from hobbyist.co.nz. Of course this is a nice bundle of hardware and code that looks like it works very well and would be handy. You could probably do something similar with the equipment you have on hand by looking through the project details.Â
