Sensor Overview
What is Sensors
Sensors in a car are electronic devices that monitor physical conditions such as temperature, pressure, speed, position, and environmental changes. They convert these measurements into electrical signals and send them to the ECU, or Engine Control Unit, which acts like the brain of the vehicle.
The ECU then analyses this data and makes real-time decisions to control systems in the car. This communication ensures optimal performance, better efficiency, and enhanced safety.

Types Of Sensors
Core Sensor Applications
Data Collection
EZMotion records digital and analogue data simultaneously and synchronizes with accelerometers, load cells, and other collection equipment. Output supports formats including TXT, CSV, M, spindle, and CAD files.
Controller
EZMotion does not require a special controller and can operate from a passenger-seat computer with easy-to-use touchscreen software for fluid operation.
Sensor Product
Speedbox - Mini
Both the SPEEDBOX and SPEEDBOX MINI are very high accuracy non-contact speed sensors designed for professional automotive testing, industrial applications, and high-end motorsport environments.
They combine GPS and inertial data using an adaptive filter for exceptional performance even when GPS conditions are not ideal. CAN, RS232, and configurable digital pulse outputs are provided as standard.

MT Pulse Transducer
The MT pulse transducer has been specially developed for measurement of wheel speed in vehicles. It supports calculation of wheel speed, distance, and vehicle speed, making it suitable for slip, acceleration, ABS tests, and other measurement tasks.
The assembly uses a robust clamping system attached directly to the rim, with optional suction or magnetic body mounting. It is available with 25 to 5000 pulses per revolution.
ADAS Testing
Steering Effort Sensor
The innovative CLSx steering effort sensor measures torque, steering angle, and velocity with high precision. It also records acceleration in the center of the steering column across x, y, and z directions, along with rotational acceleration.
Its 24-bit high-resolution A/D converters deliver excellent signal quality and low-noise results, which is especially important for ADAS and autonomous driving validation.
Distance Measurement
LHT Light Height Sensor
The LHS is used for non-contact distance measurement, pitch and roll angle measurement, and dynamic camber angle measurement. It works according to the triangulation principle and is available in different measuring ranges.
The sensor is compact and lightweight, provides CAN and analogue outputs, and can be mounted on almost all vehicles with suction or magnetic holders depending on the version.

Force Measurement
Wheel Force Transducer
The 6-component Wheel Force Transducer WFT-Cx measures all forces and torques acting on the vehicle with high precision. Its robust housing protects against dirt, water, and snow for all-weather applications.
It is also available for small cars with rims from 13 inches, including a lighter WFT-Cxs variant for applications where weight matters.
Use Cases
Wheel Force Testing Applications
Acquire load collective data from prototypes
Use WFT systems during test drives to determine real component stress in new vehicle development, even across multi-day testing.
Fatigue testing on the test stand
Durable titanium and steel housings support component lifetime testing, with telemetric transmission options and compatible adapter reuse.
Function trials during winter
The waterproof design and wide operating temperature range support testing in ice, snow, meltwater, and rough terrain conditions.

FAQs
1. What are sensors in cars?
Sensors are electronic devices that detect and measure parameters like speed, temperature, pressure, and position, and send this data to the vehicle's ECU for proper functioning.
2. Why are sensors important in a car?
They improve safety, performance, fuel efficiency, and emissions control by helping the car make real-time decisions.
3. What are the most common sensors in a car?
Common examples include oxygen sensors, temperature sensors, speed sensors, ABS sensors, and parking sensors.
4. How do car sensors work?
Sensors collect data, convert it into electrical signals, and send it to the ECU, which processes the information and controls vehicle systems accordingly.
5. Can car sensors be repaired or replaced?
Most sensors are replaced rather than repaired, and the process is usually quick and cost-effective.
6. Are sensors used in modern smart cars?
Yes, modern cars use advanced sensors like radar, cameras, and lidar for features such as adaptive cruise control and lane assist.
