Issues with current practice
High interest by public for more personalized info and by
industry/government for more connected solutions as IoT
Traditional monitoring equipment
• High price and maintenance cost;• High precision but requires professionals.
“Professional "sensors
Lower cost but small, compact, easy for deployment;
Less precision but good performance in certain range.
Consumer grade sensors
• Cheap and small for personal and family usage;• Indication purpose, not scientifically reliable.
