A Wireless and Batteryless Intelligent Carbon Monoxide Sensor

Abstract

Carbon monoxide (CO) poisoning from natural gas water heaters is a common household accident in Taiwan. We propose a wireless and batteryless intelligent CO sensor for improving the safety of operating natural gas water heaters. A micro-hydropower generator supplies power to a CO sensor without battery (COSWOB) (2.5 W at a flow rate of 4.2 L/min), and the power consumption of the COSWOB is only ~13 mW. The COSWOB monitors the CO concentration in ambient conditions around natural gas water heaters and transmits it to an intelligent gateway. When the CO level reaches a dangerous level, the COSWOB alarm sounds loudly. Meanwhile, the intelligent gateway also sends a trigger to activate Wi-Fi alarms and sends notifications to the mobile device through the Internet. Our strategy can warn people indoors and outdoors, thereby reducing CO poisoning accidents. We also believe that our technique not only can be used for home security but also can be used in industrial applications (for example, to monitor leak occurrence in a pipeline).

An Overview of Solid Fuel Processing, Kinetics, and the Advances in Minimizing Carbon Monoxide Emissions

“…Metal-oxides like tin oxide (SnO2) semiconductor sensor, a data acquisition system, and a communication system from remote terminal unit to a web server have been used for CO detection with an average error of 7.73 ppm, and a mean absolute percentage error of only 2.81% (Suryono et al, 2017). With a three-lead electrochemical CO sensor without battery (2.5 W), and the power consumption of only ~13 mW, a wireless system was set up and used with a Nordic Bluetooth dongle low power protocol to send a trigger to activate Wi-Fi alarms and notifications to the mobile device through the Internet (Chen et al, 2016).…”

Application of IoT in the Prevention of Carbon Monoxide Poisoning

“…In a preliminary study conducted by Chen et al, a smart gateway Wi-Fi alarm system and IoT notifications on mobile devices reduced CO poisoning incidents. (4) To prevent CO poisoning, in this study, we explored related problems and proposed the following solutions:…”
