A sensor data gathering environment that associates a sensor with a smart tag attached to a product. The sensor receives product identification data from the smart tag. An application, web service or a computing device associated with the sensor collects customer behavior data, such as a length of time the sensor is associated with the smart tag, the proximity of the sensor to the smart tag, the location of the sensor while in a threshold distance from the smart tag, and the like. The application, web service or the computing device associated with the sensor transmits the product identification data and the customer behavior data to a remote computing system for analysis. Based on the analysis, a message or communication is initiated to provide the customer with personalized customer service.
