Infrared sensor and infrared sensor system

The invention discloses an infrared sensor and an infrared sensor system, the infrared sensor comprises a shell and an infrared detection part, and the infrared detection part is arranged in the shell; the infrared sensor further comprises a micro-nano part, the micro-nano part is connected with the infrared detection part, the micro-nano part is arranged in the shell, and the micro-nano part is used for monitoring gas parameters in the shell, converting the gas parameters into gas electric signals and outputting the gas electric signals. According to the infrared sensor, the micro-nano part is arranged in the infrared sensor and can monitor the concentration of gas in the shell, the gas tightness of the closed shell can be analyzed through the gas concentration, and then the service life of the infrared sensor is judged; within a certain range, the sensitivity and accuracy of the infrared sensor can be improved by correspondingly adjusting the algorithm compensation of the infrared sensor. 本发明公开了一种红外线传感器及红外传
