Product Description

The role of car sensors:

 

1. Real - time Monitoring Function
   • Air Pressure Monitoring: The valve - stem sensor is capable of real - time monitoring of the air pressure inside the tire. During vehicle driving, the tire air pressure changes due to various factors, such as temperature changes, road conditions, and vehicle load. The sensor accurately detects these air pressure changes through internal pressure - sensitive elements. For example, when a car travels on a highway for a long time, the friction between the tire and the road generates heat. According to the ideal gas law, the increase in temperature leads to a rise in air pressure, and the sensor can promptly capture this change. Moreover, it has a relatively high monitoring accuracy, usually being able to be precise within a certain air pressure range, for example, with an error within ±10kPa, thus providing drivers with accurate tire air pressure information.
   • Temperature Monitoring: In addition to air pressure, the valve - stem sensor can also monitor the temperature inside the tire in real - time. When the tire is driving at high speed, braking frequently, or carrying heavy loads, the internal temperature rises rapidly. The sensor uses temperature - sensitive elements such as thermistors to detect temperature changes. For instance, when a vehicle brakes urgently, due to the frictional heat transfer between the brake disc and the wheel hub, the tire temperature may rise sharply, and the sensor can immediately detect this change and send out the data. Generally, its temperature monitoring range can cover from low - temperature environments to the maximum temperature that the tire may reach, such as from - 40°C to 125°C.
2. Data Transmission Characteristics
   • Wireless Transmission Method: Most valve - stem sensors use wireless communication technologies to transmit data. Common ones include Bluetooth technology, ZigBee technology, or dedicated radio - frequency (RF) communication bands. This wireless transmission method avoids complex wiring problems, making the sensor installation more convenient and not affecting the overall appearance of the vehicle. Taking Bluetooth transmission as an example, the sensor can establish a connection with the receiver inside the vehicle or the owner's smartphone and other devices, enabling the driver to obtain the tire air pressure and temperature data either inside the car or within a certain distance (usually, the Bluetooth transmission distance can reach about 10 meters).
   • Stable Data Transmission: To ensure the accuracy and timeliness of the data, the data transmission of the valve - stem sensor is highly stable. It adopts a series of signal - processing and anti - interference technologies. In the complex electromagnetic environment of the vehicle, such as the electromagnetic interference from the engine and the signal interference from on - board electronic devices, it can still ensure the stable transmission of data. For example, by using specific frequency bands and modulation methods, as well as data encryption and verification technologies, errors and losses during data transmission are reduced, and the transmission success rate can usually reach over 90%.
3. Early - Warning Function
   • Alarm with Preset Thresholds: The valve - stem sensor can preset alarm thresholds for air pressure and temperature. When the tire air pressure is lower or higher than the set safe air pressure range, or when the temperature exceeds the set safe temperature, the sensor will immediately issue an alarm. For example, when the tire air pressure is lower than 190kPa (this is a common lower - limit alarm setting value) or higher than 280kPa, the sensor will issue an audible - visual alarm or a vibration alarm through connected devices (such as the vehicle's dashboard or the owner's mobile APP). Similarly, when the tire temperature exceeds 100°C, the alarm mechanism will also be triggered, reminding the driver to take timely measures, such as stopping to check and adjusting the air pressure, effectively preventing safety accidents such as tire blowouts.
   • Fault Alarm: In addition to abnormal air pressure and temperature alarms, the valve - stem sensor can also alarm for its own faults. If the pressure or temperature - detecting elements inside the sensor fail, or if the wireless communication module has problems and cannot transmit data normally, it will also send out a fault alarm signal. This ensures that the driver will not receive incorrect tire - state information due to sensor failure.
4. Durability and Adaptability Characteristics
   • Durability: The valve - stem sensor usually has good durability and can adapt to various harsh environments of vehicle driving. Its outer casing is generally made of durable materials, such as high - strength plastics or metal alloys, which can resist certain degrees of collision, vibration, and corrosion. During vehicle driving, the tire will be subject to road bumps, stone impacts, etc. The sensor, installed on the valve - stem, also needs to withstand these external forces. For example, its outer casing can withstand an impact force of at least 100N without damage, and it can still work normally under long - term vibration environments (such as driving on bumpy roads), with a service life of several years.
   • Environmental Adaptability: The sensor can adapt to a variety of different environmental conditions. Whether in a high - temperature desert environment (with a temperature reaching over 50°C), a cold polar environment (with a temperature as low as below - 40°C), or in humid coastal areas or high - altitude areas, it can work properly. This is because its internal elements are specially designed and packaged, and can resist the effects of temperature changes, humidity changes, and air pressure changes, etc. For example, its pressure and temperature - detecting elements adopt waterproof and moisture - proof packaging technologies, and will not have short - circuits or excessive measurement errors even when the humidity reaches over 90%.
