A car moves with a speed of 50 km/hr. What will be the speed of a stationary bicycle parked along the roadside measured by a speed sensor which is placed in the same car?

Sensors and Transducers topics include: Transducers types, characteristic parameters, static and dynamic characteristics.

Sensors and transducers are both electronic devices that measure or detect physical processes and phenomena. 

Here are some differences between sensors and transducers:
Sensors: Detect and respond to a specific input, such as light, temperature, pressure, or motion. Sensors convert the input into a measurable output.
Transducers: Convert one form of energy into another. Transducers have a broader function, encompassing sensors, actuators, and devices that convert energy between different forms. 

Here are some examples of sensors and transducers:

Current sensors: Measure the AC or DC current flowing through a conductor. They convert the current into a proportional electrical signal that can be measured and analyzed.
Pressure sensors: Generate a signal related to the pressure imposed. Typically, such a signal is electrical. Pressure sensors are often fabricated using thin membranes that flex under pressure.
Proximity sensors: Detect objects or signals that are near the sensor element. Inductive proximity sensors work by generating a magnetic field and detecting the current losses of said field when ferrous and non-ferrous detection objects are introduced into it.
Temperature sensors: Convert a temperature reading into an electrical output that becomes a proxy for the level of temperature. Temperature sensors are used in both industrial applications as well as in commercial and consumer products.
Humidity sensors: Measure the amount of water in the air and convert these measurements into signals that can be used as inputs to control or display devices.
