Abstract:
1. A temperature measuring apparatus comprising: a microprocessor; a first thermal sensor linked to the microprocessor and having a relatively high thermal absorbency; and a second thermal sensor linked to the microprocessor and having a relatively low thermal absorbency, wherein the microprocessor is configured to receive from each of the first and second sensors a first temperature reading and a second temperature reading, the first temperature reading being indicative of a temperature sensed at a first instant of time, the second temperature reading being indicative of a temperature sensed at a second subsequent instant of time, and wherein the microprocessor is further configured to determine at least one environmental condition based on the relative change in temperature sensed by the first sensor from the first to the second instant of time, and based on the relative change in temperature sensed by the second sensor from the first to the second instant of time.
