Rancang Bangun Alat Ukur Kadar Hidrokarbon (HC) pada Gas Buang Kendaraan Menggunakan Sensor MQ-7 Berbasis Mikrokontroler ESP8266

Abstract

I have conducted research by making the title “Design of Hydrocarbon (Hc) Level Measurement Tool in Vehicle Exhaust Gas Using Mq-7 Sensor Based on ESP8266 Microcontroller. Using the components of the Mq 7 Sensor, 18650 Battery, ESP 8266 Microcontroller, Internet Of Things / Telegram. MQ-7 gas sensor as HC gas detector. As an indicator of Hydrocarbon (HC) gas, LCD and Tele are used to provide information about HC gas levels in the air based on air quality criteria. The measurement and calibration results of the design of the hydrocarbon (HC) measuring instrument against the MQ-7 gas sensor have been well calibrated. I hope that after doing this research the test results from my research show that the designed tool can measure hydrocarbon levels within the expected range with an adequate level of accuracy for environmental monitoring applications. Based on the testing results of the MQ-7 sensor testing that ppm values <36,000 produce good air while ppm values >36,000 produce alert air.
