In my project i want to get the acceletometer data of vibrating object throught the arduino. but all the wires making my system very clumsy and effect the measurements badly. is there any accelerometer that could conncet the arduino wirelessly (with built-in bluetooth or something)??
I think that best will be to use arduino pro mini or similar and some wireles module (for example NRF24L01) and of course some accelerometer. This will be quite small and quite cheap (I think about 10$ for everything).
