Probably, every motorist at least once left his car on the street with half-open windows in the summer or with the lock unlocked. Naturally, leaving a car like this overnight is very dangerous, but today we will tell you about a tool that can protect any vehicle from theft. This device is the so-called volume sensor. This device allows you to respond to the slightest movements inside the car and, unlike shock sensors, does not give false alarms. So, let's figure out what this device is, how much it costs, what types there are.
What is it for?
The main task of each sensor is to respond to the penetration of thieves into the car and notify the driver with a sound signal that someone is fumbling in the car. It does not matter if your transport is open or closed. In any case, the volume sensor will notify its owner about various movements in a certain protected area (that is, in the cabin). False alarms are kept to a minimum here as this tool does not respond toto strike, but to move or approach intruders to the car.
Varieties
Today, all existing volume sensors can be divided into three types: microwave, infrared and ultrasonic. The latter variety is the weakest and least effective, and therefore it is almost impossible to find such devices on cars. Microwave volume sensors are characterized by poor sensitivity to the movement of various insects and dust. And infrared devices are the most modern, efficient and popular among domestic motorists.
Properties
Each volume sensor can be set to a certain range. But, in order for it to react essentially, you need to install it correctly. In each sensor model, the manufacturer himself indicates where and how to install it in the cabin. Some drivers even set an excessively large range so that anyone who came close to the car was "cursed" by the alarm. But if you look at it from an objective side, then such a setting is not effective, since every 5 minutes the driver will jump out into the yard and turn off the siren. And it will not bring any benefit to the battery.
Also an important characteristic of sensors is their effectiveness in relation to unauthorized penetration of intruders into the machine. And even if the thief quietly breaks open the door or turns off the shock sensors, he is unlikely to think about the existence of another security system that will just raisealarm.
Volume sensor: device price
Today, the average cost of a microwave sensor varies from 700 to 800 rubles. Well, the most effective, infrared, device will cost 1200 rubles. Considering how useful these sensors can be, the cost is quite reasonable.
Remember - if you take care to install additional security measures, your iron friend will never be stolen by car thieves.

Phase sensor "Kalina". Replacing the phase sensor
Using the phase sensor, it is possible to track the position of the camshaft. It is not installed in carburetor engines; they were not on the first copies of injection systems either. But it can be found in almost all engines with 16 valves. An eight-valve engine is equipped with such devices only if they comply with Euro-3 toxicity standards, have a phased or sequentially distributed injection of the fuel mixture
What should be the volume of oil in the engine and how to determine its level?
Engine oils are truly indispensable in a car, because their condition, properties, viscosity and degree of pollution determine the strength of a thin oil film, which provides parts with extreme pressure properties and absorbs all dirt and deposits. At the same time, this material protects the engine from corrosion, thereby increasing the service life of all its parts
