A sensor includes a housing, a circuit board, and a sensor chip fixed on the circuit board. The housing defines a receiving cavity and a first channel extending through the housing. The first channel communicates with the receiving cavity and an outside of the sensor. The circuit board is at least partially received in the receiving cavity. At least a part of the circuit board is bonded and fixed to the housing by a thermal conductive glue. The sensor chip is adapted for sensing at least one of a humidity signal and a temperature signal of an environment in the receiving cavity. As a result, the monitoring accuracy is relatively improved.

Sensor and heat exchanger

The present disclosure discloses an infrared sensor, an infrared gas detector and an air quality detection device. The infrared sensor includes electrodes, a substrate, an isolation layer and a graphene film. The graphene film has a periodical nanostructure. The infrared sensor enhances the absorption of infrared light, and is capable of only absorbing specific infrared wavelengths, thus improving the selective performance of the infrared gas detector.
