Specifically, the level and state of the oil are attached by attaching a sensor to the dipstick. The present invention relates to an oil dipstick that provides scientific management of driver convenience and vehicle optimization.

In general, the vehicle is equipped with a dipstick in the mission oil and engine oil, and the dipstick is used to check the condition of the oil by visually observing the oil level (level or amount), color and viscosity. . Since this leads to very subjective judgment, it is not only difficult to determine the correct oil state, but also causes inconvenience for the user.

Engine oil and mission oil in the vehicle are very important materials for lubrication and heat dissipation to protect the metal structure from mechanical friction and heat generation of the vehicle. However, these oils are denatured as the oil's role increases as the use time increases. Therefore, the oil must be replaced in this case to maintain the optimum state of the vehicle. To understand the condition of the end of life of this oil, open the cover of the vehicle with the oil and pull out the dipstick gauge with the stop and engine starting off, and visually check the oil level (volume) and color (state). Figure out.
