A dispensing assembly (205) has a dispensing chamber housing (425), a temperature control device (450), a thermal sensor (460), and an interface (530). The dispensing chamber housing has an inner surface, an outer surface, and a wall thickness. The inner surface partially defines a dispensing chamber ~(405) for receiving a quantity of a substance. The temperature control device at least partially surrounds the dispensing chamber housing. The temperature control device alters a temperature of a substance in the dispensing chamber. The temperature control device and the thermal sensor are located on a substrate. The substrate is wrapped around an exterior surface of the dispensing chamber housing. The interface is connected to the temperature control device and the thermal sensor. An interface connector (520) is connected to the interface. The distance between the temperature control device and the thermal sensor is approximately equal to the wall thickness of the dispensing chamber housing.
