IoT sensors refer to sensors used in smart applications, which require uninterrupted connectivity to carry out real-time data analytics. They require common connecting platforms for collecting and analyzing data. IoT sensors are based on the computing concept that considers every physical object to be connected to the Internet to communicate with each other. Sensors are the most important component in the IoT ecosystem. They gather required data from their surroundings and communicate it to the concerned operators. Image, temperature, pressure, ultrasonic, light, and position sensors, accelerometers, and gyroscopes are the key sensors in the IoT ecosystem.
