There are hook type weighing machine that take weight measurement. You can check out on amazon or [login to view URL] (like [login to view URL]) want it to be passing weight measurement via bluetooth to android phone... U will need to adapt the device to send data to android. U can buy or i can buy the device which will need to be prototyped the device should support weights upto 100 kg.. I am open to language to be used...c++, C# , Java., .net micro .... If it may require interfacing via Arduino or via rasberry pi or Netduino then let me know beforehand.. if it can be directly implemented, it would be all fine also....u will need to identify the base weihing machine which u would implement it upon... If Bluetooth is not available then the scale may be connected to the android device via usb cable
