There are several types of sensors commonly used in IoT, including: Temperature Sensors – These sensors measure and monitor temperature changes. Humidity Sensors – They track the level of humidity or moisture in the environment. Proximity Sensors–Within a limited range, these sensors detect the presence or absence of things. Motion Sensors – These sensors detect movement, enabling applications like security systems. Light Sensors – Light sensors measure the intensity of light, adapting devices to ambient lighting conditions. Pressure Sensors – These sensors measure pressure, enabling applications like weather monitoring or tire pressure monitoring systems. Gas Sensors – They detect the presence and measure the concentration of gases, ensuring safety in various environments. Accelerometers – Accelerometers measure acceleration or changes in motion, commonly used in fitness trackers or navigation devices. GPS Sensors – GPS sensors provide location information, facilitating tracking and navigation applications. Image Sensors – Image sensors capture visual information, enabling applications such as surveillance cameras or facial recognition systems.
