  • Publication number: 20230349768
    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.

  • Publication number: 20220316951
    Abstract: An infrared temperature sensor comprises a thermopile sensor and an infrared reflector, wherein the infrared reflector reflects the infrared ray radiated by a target to a first thermopile sensing element of the thermopile sensor to sense the temperature of the target. By appropriately designing the reflecting surface of the infrared reflector, a horizontal viewing angle of a sensing range of the infrared temperature sensor can be larger, while a vertical viewing angle is smaller. The thermopile sensor further comprises a second thermopile sensing element, which can sense the thermal radiation of a package structure, whereby to compensate for the measurement error induced by the temperature variation of the package structure, which results from the variation of the environmental temperature. Thus, the measurement accuracy is increased.

  • Publication number: 20210364359
    Abstract: An infrared temperature sensor comprises a thermopile sensing chip. The thermopile sensing chip includes a chip substrate, a thermopile sensing unit, a heater and a temperature sensing element. The thermopile sensing unit is disposed on the chip substrate, receives infrared thermal radiation from a target and outputs a corresponding infrared sensation signal. The heater is disposed on the chip substrate and used to heat the chip substrate to a working temperature. The temperature sensing element is disposed on the chip substrate, senses the working temperature of the chip substrate and outputs a corresponding working temperature signal. In operation, the infrared temperature sensor can maintain the thermopile sensing unit at the preset working temperature. Thereby, a single-point temperature calibration is sufficient to obtain more accurate measurement results in a broad environmental temperature range.
