515 Applications of Sensors

IoT Sensor Applications Across Domains

515.1 Overview

Sensors are the fundamental building blocks of Internet of Things (IoT) systems, serving as the interface between the physical and digital worlds. This series explores the diverse applications of sensors across 12 major domains, covering 61 specific use cases from smart cities to healthcare.

Comprehensive IoT sensor applications diagram showing six major application domains: Smart Cities (parking sensors, traffic monitoring, street lighting, waste management, air quality), Healthcare (wearable vital signs, patient monitoring, fall detection, medication tracking), Agriculture (soil moisture, weather stations, livestock monitoring, precision irrigation), Industrial IoT (vibration monitoring, predictive maintenance, quality control, asset tracking), Smart Home (occupancy detection, HVAC control, security systems, energy monitoring), and Transportation (fleet tracking, vehicle diagnostics, autonomous navigation, cargo monitoring). Each domain shows typical sensors used and data flow to cloud platforms. — IoT sensor applications across domains
