We did some tests with a Newgen Medical treadmill:
DC Rainmaker made some tests about treadmill calibration:
But none of treadmill speed sensors which are currently on the market fit’s our needs. We found out with our Newgen Medical treadmill that if we have set the speed to 4 km/h for walking meditation on the treadmill and the speed is tracked with Treadtracker sensor and a training tracker, the treadmill computer as well teadtracker shows 4 km/m if no one walks on the treadmill.
But as soon as we step onto the treadmill and start walking, the speed which is indicated on the treadmill computer stays at 4 km/h, but the speeds which is indicated measured by the Treadtracker drops to around 3.2 km /h.
Treadmill computers are known to be not very accurate. But from what we have observed here we suppose that the speed in the Newgen Medical treadmill is given by the treadmill computer, and the speed correlates with the amound of current which is given to the treadmill motor, and this seems to be calcuated from a treadmill without a runner. It seems nothing which is measured from the treadmill.
But a Raspberry Pi treadmill speed sensor does not cost that much:
But it has to be recoded for our application. But we then can regulate our treadmill motor with the measured speed data. The easiest solution is eventually to replace the treadmill motor by a new one which offers all the schematics and the specifications. There a lot of treadmill controllers available. If we use a treadmill as our daily tool, it is eventually worth studying these instructions until we find one which fit’s our needs.
