AUDIOWELL I sensor technology APA Ultrasonic Sensor The APA ultrasonic sensor is the key component of the automatic parking assist system. It uses ultrasound to measure the distance to obstacles near the vehicle, from which the size of the parking space and the vehicle's position can be calculated. It operates at a different frequency from the reverse parking sensor to avoid interference. Features - Long detection range, up to 5000mm - Excellent directivity - No interference with reverse parking sensors Applications - Automatic parking system

UPA Ultrasonic Sensor UPA ultrasonic sensor is the core component of Parking System. It uses ultrasound to measure the distance between the vehicle and the front and rear obstructions. Features - Measuring range 150mm-2500mm - Low power consumption - High reliability - Excellent waterproof performance and weatherability Applications - Parking assist system - Blind zone detection Audiowell Catalogue

AUDIOWELL I sensor technology Assembled Parking Sensor The assembled parking sensor is an assembled ultrasonic sensor module, which consists of sensor, silicone ring, plastic housing and cable. It can be connected directly with the signal processing module, and is the key component of a parking system. Features - High sensitivity, low power consumption and strong antiinterference ability - Adaptable to a diversify of ECUs and car models - Excellent waterproof performance and weatherability, suitable for humid and dusty environments Applications - Parking assist system

Digital Ultrasonic Sensor The Digital Ultrasonic Sensor uses the ultrasonic time-of-flight principle to accurately measure the distance between the sensor and the obstacle. The sensor outputs digital distance signal and self-test information with various communication protocols such as LIN bus and 2/3-wire IO, which makes it suitable for a variety of intelligent parking systems. Features - Digital signal output - High accuracy and reliability - Built-in circuit which matches the self-developed transducer Applications - Intelligent parking systems - Blind spot detection systems - Obstacle...

AUDIOWELL I sensor technology Ultrasonic BSD Sensor The Ultrasonic BSD Sensor is designed for blind spot detection. Featuring a wide detection angle and a long measuring distance, this sensor can detect other vehicles located to the driver's side and rear. Features - Blind zone detection - Wide detection angle - 3.5M detection range - High accuracy Applications - Blind Zone Monitoring Solution

Open-type Ultrasonic Sensor ROA system ( Rear passenger monitoring system) uses open type ultrasonic sensor to measure the moving object in the vehicle rear seat. The principle is TOF (Time of flight). When there is any moving object in the rear seat, such as human or pet, the driver will be reminded by the alarm. Features - Large detection range - Good immunity to interference Applications - Rear passenger monitoring system (ROA system) - Anti-theft alarm device Audiowell Catalogue

AUDIOWELL I sensor technology DEF/AdBlue Sensor is designed to measure the level of the urea solution (DEF/AdBlue) in the Selective Catalytic Reduction (SCR) system for diesel engines. Unlike the traditional reed level sensor in which the float sender can get stuck, this sensor uses ultrasonic wave to measure the liquid level and therefore contains no moving part. It has higher accuracy and reliability than typical reed sensors. This product can also be used as a diesel level sensor. Features - Continuous measurement - High accuracy (four times as high as the traditional reed level sensor)...

Hall Speed Sensor The Hall Speed Sensor detects the speed and direction of gear rotation based on hall effect. Measurement is accomplished without contacting the target gear. It measures the change of magnetic field induced by gear tooth and tooth gap with dual differential signals. The output signals are two-channel square waves with 90°phase shift, and the direction of rotation is determined by their lead/lag phase shifting. Features - High reliability even in harsh environments - Wide measurement range ensures high accuracy for high/low speed - Digital output for easy programming...

AUDIOWELL I sensor technology Low Frequency Buzzer The low frequency buzzer is a piezoelectric buzzer with frequency lower than 1 KHz and no coil structure. It consumes only one third of the power of electromagnetic buzzers and fully complies with EMC standards. Features - Low resonant frequency - High immunity to electromagnetic interference Applications - Parking system

The piezoelectric buzzer generates mechanical deformation of piezoelectric ceramic plates by reverse piezoelectric effect, which induces the vibration of vibrators and forms sound wave in the air. This one-piece electronic sound device is widely applied in automotive electronics, security alarming, etc. Applications - Paking alarm system - Anti-theft alarm system Audiowell Catalogue
