Abstract
Method for conveying driving conditions includes determining when a vehicle is within a set distance from an activatable sensor using a proximity sensor coupled thereto. Only when the proximity sensor determines that the vehicle is within the set distance from the activatable sensor, the activatable sensor is activated (from a deactivated state) to measure or detect a property or condition of the travel surface or the environment around the travel surface that affects interaction between tires of the vehicle and the travel surface using a measuring or detecting component, and communicate the sensor-generated information directly from the activatable sensor to the vehicle or occupant thereof. Energy is provided to the activatable sensor from an energy harvesting system associated with the activatable sensor to enable it to measure or detect the property or condition of the travel surface or the environment around the travel surface.
