Sensors Introduction

 

Sensors in IoT

Sensors in IoT are devices that detect and respond to changes in the environment. They collect data such as temperature, humidity, pressure, light, and motion, which is then transmitted to IoT systems for analysis and action. These sensors enable smart devices to interact with the physical world and automate processes across various industries.

Two IoT Sensors with Definitions

1. Temperature Sensor:

• A temperature sensor measures the degree of hotness or coldness in an environment.
• It converts temperature readings into electrical signals for monitoring and control purposes.
• Commonly used in smart thermostats, weather stations, and industrial temperature regulation systems.

1. Proximity Sensor:

• A proximity sensor detects the presence or absence of an object, or measures the distance to an object, without physical contact.
• It uses electromagnetic fields, light, or sound to sense objects.
• Often employed in security systems, automated doors, and industrial machinery for object detection.
