1.29 Wipers
Wiper

1、 Overview of the plan:
The wiper gears can generally be divided into the following 7 types:
1. Self sensing wiper. There is a rain sensor on the front windshield, which can choose to turn on the wipers and select the appropriate gear according to the amount of rain. The two mainstream rain sensors that are currently widely used are optical rain sensors and capacitive rain sensors.
2. Quick scraping. The car wiper is used for fast and continuous wiping in heavy rain and rainstorm.
3. Normal scraping. The car wiper is used for continuous operation during moderate to light rain.
4.0 gear. Stop the gear and place it in this gear when not using the car wiper.
5. Spray water and scrape. Spray out wiper fluid and activate the front wiper to clean the front windshield. Mainly used for cleaning windshield, there are two methods of button or push control. Stop pressing or push and reset yourself, and the wiper will automatically stop.
6. Scratch it. It will automatically reset (i.e. automatically stop after one scraping) in the opposite direction of the normal scraping start direction. Mainly used when there is no rain but water on the windshield.
7. Intermittent scraping. When there is not much rain, when using this gear, the wiper will wipe every few seconds.
