Over the past few years, the IoT has become one of the most important technologies of the 21st century. Now that we can connect everyday objects (appliances, cars, thermostats, baby monitors) to the Internet via embedded terminals, seamless communications are possible between people, processes and objects. Thanks to low-cost computing, the cloud, Big Data, analytics and mobile technologies, physical objects can share and collect data with minimal human intervention. In this hyper-connected world, digital systems can record, monitor and adjust every interaction between connected objects. However, the environmental sector is struggling to maintain its state of cleanliness due to the multiple services offered by the IoT. To this end, we provide you with devices for measuring environmental pollution, by measuring the microgram level per cubic meter of atmospheric pollutants.
