Abstract

The invention discloses a temperature and humidity sensor and a method for detecting an automobile gas circuit by adopting the temperature and humidity sensor. The temperature and humidity sensor comprises a filter connector, the filter connector being internally provided with a cavity, and the filter connector being provided with a plurality of through holes; a temperature and humidity sensor module, mounted in the cavity of the filter connector; a sensor shell, connected with the bottom of the filtering connector; a wire harness, electrically connected with the temperature and humidity sensor module. The detection method comprises: using the temperature and humidity sensor for detecting the temperature and humidity of the automobile air channel. The temperature and humidity sensor is a brand-new designed product meeting the automobile characteristics in the automobile intelligent development stage, and solves the problem that in the prior art, no similar detection device exists in the automobile air channel to detect the air dryness of high-pressure air in the air channel. And the performance safety problem of related parts with a very large air source air dryness relation in automobile parts is also solved.

Description

technical field [0001] The invention relates to the technical field of automobile gas path detection, in particular to a temperature and humidity sensor and a method for detecting the gas path of an automobile using the temperature and humidity sensor. Background technique [0002] Currently, vehicles primarily use pneumatic systems for parking braking. The energy supply device and transmission device of the pneumatic brake system are all pneumatic components; the parking pneumatic brake system generally includes an air compressor, an air dryer, a multi-circuit protection valve, a manual brake valve, a quick release valve and a spring brake. moving cylinder. The air compressor directly provides the compressed air required for braking. The compressed air output by the air compressor enters the air dryer to dry and filter moisture, and then is controlled by the multi-circuit protection valve to enter the service brake air circuit and the parking brake respectively. Air circu...
