Will the cold weather affect the door sensing?

Cold weather will affect the induction of the door. The solution of key sensing failure in cold weather is that each remote control key is equipped with a mechanical key, which can be used to open the door. When the mechanical key is used to open the door, the anti-theft system of the vehicle will be triggered, and the alarm will be automatically lifted after the vehicle is started. As a result, the vehicle can't receive the signal, the remote control key is dead or the battery is too low, and the antenna of the door remote control transmitter can't be opened, resulting in poor contact.

Door induction principle

The principle of infrared sensor Generally, the human body temperature is constant, generally 37 degrees, so it will emit infrared rays with a specific wavelength of about 10UM. The working principle of passive infrared probe is to detect infrared rays emitted by human body. The infrared ray emitted by human body is about 10UM, which is enhanced by Finuer filter and concentrated on the infrared sensor.
