Abstract: A temperature sensor device for a power distribution panel includes a Power over Ethernet (PoE) interface, a DC-to-DC step down converter, at least one infrared temperature sensor array, a microcontroller and a communication interface. The PoE interface is used to obtain a required power supply from the Ethernet network. The DC-to-DC step down converter steps down the power supply from a first voltage to a second voltage. The infrared temperature sensor array receives infrared rays radiated from a monitored area of the power distribution panel and generates a corresponding sensation signal. The microcontroller receives the sensation signal and generates an alert signal when the sensed temperature of the monitored area exceeds a preset threshold. The threshold can be dynamically adjusted according to time of day or day of months. The communication interface enables the communication between an external electronic device and the temperature sensor device for the power distribution panel.

Abstract: An infrared temperature sensor comprises a first communication port and a second communication port. A plurality of infrared temperature sensors can be cascaded to each other and connected to an external host controller through the second communication port. The external host controller can set up and administer the unique addresses of the plurality of the infrared temperature sensors through the second communication port, whereby to selectively perform multicasting communication or unicasting communication with the plurality of infrared temperature sensors through the first communication port. The infrared temperature sensor further comprises a second thermopile sensing element used to sense the thermal radiation of a package structure, whereby to compensate for the measurement error induced by temperature variation of the package structure. Thus, the measurement accuracy is increased.

Abstract: An infrared thermopile sensor includes a silicon cover having an infrared lens, an infrared sensing chip having duo-thermopile sensing elements, and a microcontroller chip calculating a temperature of an object. The components are in a stacked 3D package to decrease the size of the infrared thermopile sensor. The infrared sensing chip and the microcontroller chip have metal layers to shield the thermal radiation. To measure object temperature accurately under acute change in environmental temperature, this disclosure uses the duo-thermopile sensing elements, that one is the active unit for measuring the object temperature and another one is the dummy unit for compensating the effect from the package structure.

Abstract: An infrared thermopile sensor includes a silicon cover having an infrared lens, an infrared sensing chip having duo-thermopile sensing elements, and a microcontroller chip calculating a temperature of an object. The components are in a stacked 3D package to decrease the size of the infrared thermopile sensor. The infrared sensing chip and the microcontroller chip have metal layers to shield the thermal radiation. The conversion from wrist temperature to body core temperature uses detected ambient temperature and fixed humidity or imported humidity level to calculate the body core temperature based on experimental data and curve fitting. The skin temperature compensation can be set differently for different sex gender, different standard deviation of wrist temperature and external relative humidity reading.
