What are sensors? Give static and dynamic characteristics of sensors. How sensors differs from actuators? Discuss the role of Sensors and Actuators in IoT. Also elaborate, How Machine to Machine (M2M) technology differs from IoT.

Sensors are devices that detect and measure physical phenomena from the environment and convert them into signals or data that can be processed, interpreted, and used by electronic systems. They are integral components in various fields, including IoT (Internet of Things), where they play a pivotal role in collecting real-time data from the environment. Sensors can be designed to detect a wide range of physical, chemical, and biological factors such as temperature, humidity, motion, pressure, light, sound, and more. The data collected by sensors is then transmitted to other devices or systems for analysis, action, or decision-making processes.

Static Characteristics of Sensors:

Static characteristics refer to the sensor’s performance under steady-state or non-varying conditions. These characteristics are essential in determining the accuracy and reliability of the sensor’s measurements. Some key static characteristics of sensors include:

1. Accuracy: This refers to how closely the sensor’s output matches the true value of the measured quantity. A sensor with high accuracy will provide readings that are very close to the actual value being measured.

2. Precision: Precision refers to the sensor’s ability to provide consistent results when measuring the same quantity under the same conditions. _________ ______ ___ ________ __________ _____ _________.
