1. SENSOR BASED MONITORING
Emerging Technologies

2. Introduction
 Sensors are devices that respond to a physical,
stimulus heat, sound, light, pressure, magnetism,
motion etc to convert that into an electrical signal.
 They perform an input function
 Devices which perform an output function are
generally called actuators .
 Both sensors and actuators are collectively known
as transducers.

3. Types of Sensors
 Smart sensors hybrid
 Integrated smart sensors
Application of Sensors
In industries machines and equipments are
monitored and controlled for temperature ,
humidity level, pressure and also vibrations.

4. Advantages of Sensors
 The smart sensors take over the conditioning and
control of the sensor signal and the load on the
control system, allowing faster system operation.
 It provides high accuracy, not achievable with along
control systems and central processing .
 Individual controllers can monitor and control more
than one process variable.

5. Disadvantages of Sensors
 If upgrading to smart sensors, care has to be taken
when mixing old devices with new sensors, since
they may not be compatible.
 If a wire is fails, then the total system is down.
