Beat Sensors for Smart Environment Monitoring Systems

This paper introduces Beat Sensors which are suitable for smart environment monitoring as low power and small size IoT sensors. As a typical representative, the Ethanol Beat Sensor is realized to monitor the ethanol concentration from 0 to 200 ppm at almost 20 ppm resolution. Beat Sensor has large potential to address issues of smart environment monitoring such as air pollutions management. Moreover, the long distance (LoRa) communication protocol is applied to build a smart and energy efficient monitoring system.
