1. A method for detecting stability of a ladder, the ladder comprising a pair of side rails, a plurality of steps that extend between the side rails, a sensor coupled with the ladder and configured to detect loading on the ladder, the method comprising:
communicating wirelessly, by a remote computing device, with the sensor;
detecting, by the remote computing device, a presence of a user on the ladder;
during the presence of a user on the ladder, monitoring the sensor; by the remote computing device, for an instability condition; and
when the instability condition occurs, generating an alert of the instability condition.
