IOT SENSORS are new-age next-gen sensors that collect data about a real-time variable in a measurable way. Such sensors enable IOT platforms to work intelligently with the data being shared across all connected devices across the network. The objective is to use data from the surroundings to enable everyday devices to function autonomously smartly.
Motion detectors are able to detect motion or movement of objects, humans, or animals. To a great extent such sensors are used in the security industry – for example automated gates or security alarms to prevent unauthorized intrusion in smart homes. Motion sensors are also used in watches that help detect location changes.
Modern businesses today depend on Internet-of-Thing sensors to prevent downtime and engage in predictive maintenance. The data gathered helps leaders to understand significant trends and make informed decisions. Multiple such sensors are used to design solutions for our smart homes, automate vehicles, enable seamless healthcare, and large-scale manufacturing.
These sensors help detect water quality. They are used by government bodies, researchers, and businesses in detecting the presence of harmful micro-organisms in potable water. Such sensors also play a key role in maintaining aquatic and marine life. In smart homes, hotels, and wellness centres, these sensors help in visitor safety in swimming pools.
There are ten popular IOT SENSORS that get used in building IOT applications. These are Noise sensors, Temperature sensors, Gyroscope sensors, Image sensors, Chemical sensors, Gas sensors, water-quality sensors, Humidity sensors, Motion sensors, and Optical sensors. These types are categorized based on the stimuli that they receive- sound, temperature, and so on.
Gyroscope sensors detect velocity or speed and are used in the automobile industry – for example, in-car navigation and anti-skid systems. These are used by the gaming industry in video games. Gas sensors are able to understand the change in air quality. Carbon dioxide detectors in homes and industries use this sensor type.
Optical sensors absorb light stimuli. They are used in the automobile and healthcare industry. For example, optical sensors in vehicles help in recognizing objects nearby, and in developing smart parking apps. These sensors are used in making different testers and equipment used for assessing the performance of different organs of the body.
Chemical sensors detect a change in chemical-levels in the atmosphere or liquids. These are used in the healthcare industry, for example, in blood pH tracker, and glucose monitoring devices. They also play a vital role in keeping a check on environmental pollution and in manufacturing industries.
Temperature sensors sense heat or temperature changes; while humidity sensors are able to detect the presence of water vapour in the air. Temperature sensors are mostly used in shop floor machinery while humidity sensors are used in HVAC systems and in meteorology offices for predicting weather conditions.
Image sensors convert an image into a digitized signal. They are used in surveillance areas, in the healthcare industry during patient diagnosis, in RFID tags, and barcode scanners. Noise sensors capture acoustic signals and are used by the construction industry and in smart homes for the safety of homes.
