The
latest online issue of Sensors & Transducers Magazine is now available. Featuring a nifty
little transaxel accelerometer, with a "sensitivity of 5 mV/g and a measurement range of В±1000 g peak", a "
strain guage direct to PC" device, and a paper on
remote electromagnetic field monitoring!
So ... I guess you could build a robot that measures the bumpyness of
terrain and the strength of the magnetic field, all the while
outputting strain guage data to a PC.
Very clever ...
