Application Integration Monitoring Carbon Monoxide (Co) Gas Level Based on Esp8266 and Telegram

A study designed an integrated carbon monoxide (CO) gas level monitoring application with ESP8266 and Telegram modules. Carbon monoxide is a toxic gas that is undetectable by human senses, so real-time monitoring is important to prevent health risks. This system uses an MQ-7 sensor to measure the gas concentration, which is then transmitted via ESP8266 and informed to the user via Telegram. The methodology includes design, functionality testing, and performance analysis under various conditions. The results show that the system is effective in detecting CO levels and providing a quick response, thus raising awareness of the dangers of toxic gases and offering a practical solution for air quality monitoring. This research is expected to contribute to the mitigation of health risks due to exposure to carbon monoxide gas.
