Abstract: The inventive temperature sensor 10 may include a housing having an upper portion 18 and a lower portion 22. Upper portion 18 may include a cap 24 and a base 26. Cap 24 and base 26 may define a fluid passage 70 which is configured for enhancing the flow of ambient air into the region of a wall 60. A hole 54 may extend into wall 60 and be sized for receiving a temperature sensor 14 therein. In that manner, a temperature sensing device 58, such as a thermistor, may accurately and precisely measure the temperature of ambient air, while being protected by wall 60.
