Wireless cadence sensor affected by temperature?
I bought a new cyclocomputer with wireless cadence. It's @#!$ cold out there. When my bike is indoors, I can spin the pedals, hear the magnet "click", and see the cadence display on my computer. When I go for a ride, I get cadence for only a few minutes, then no cadence.
I have stopped and checked to be sure the magnet/sensor are still in range (they are). Temperature seems to be the only difference. Btw, there is no problem with the speed sensor, it keeps working in the cold. If it isn't obvious already, the speed and cadence sensors are separate; it's not a combined unit.
Is this a common problem? Or maybe I've just got a weak battery in the cadence sensor? I don't have any spare CR2032's right now, else I would have swapped one in before posting this.
