Zusammenfassung:The present invention relates generally to sensor devices. More particularly, but not by way of limitation, the present invention relates to devices and methods for monitoring and communicating environmental conditions such as temperature, pressure, humidity, solar radiance, etc. A device and method for measuring temperature is disclosed. The device, for example, can include a thermocouple configured to generate a voltage indicative of a junction temperature; a memory device configured to store a unique device ID and to store data; a logic unit connected to the thermocouple and the memory device; an I/O interface connected to the logic unit, the I/O interface configured to communicate with a computer system; and an internal temperature sensor connected to the logic unit, the internal temperature sensor configured to determine a cold junction temperature.
