Applying Frugal Innovation to Humidity and Temperature Monitoring

This paper illustrates a possible solution to monitor humidity and temperature in indoor scenarios where it is crucial to maintain their values between predefined thresholds (e.g., museums). The system architecture is composed of wireless sensors, a gateway also including a wireless receiver and a Raspberry PI, a cloud database and a user interface. We illustrate how our system can be implemented following a frugal innovation approach, using non expensive wireless sensors and weather stations to create a cloud IoT real-time infrastructure.
