It is an electronic device that collects data from a sensor or machine and transmits this data using the internet for storage and further analysis. Unlike traditional data loggers, IoT-based data loggers offer capabilities such as monitoring ‌, remote access over a range of distances, and cloud integration. They measure parameters such as temperature, humidity, voltage, pressure, and any kind of parameter; they keep them continuously and reliably track them. The combination of wireless communication and smart processing makes it ideal for applications in industries such as manufacturing, agriculture, logistics, energy, and smart cities.
