RANCANG BANGUN MOBILE ROBOT PENDETEKSI GAS CARBON MONOXSIDE (CO) MENGGUNAKAN SENSOR MQ-7 BERBASIS ARDUINO

Various kinds of technology created in the environmental monitoring system that serves to avoid humans from harmful gases like Carbon monoxside gas (CO), this gas when inhaled human being in excess will cause adverse effects. In making this tool, robot detection Carbon monoxide gas (CO) function to avoid negative impacts on humans. This tool is controlled by an Arduino Uno manifold ATMega 328, this microcontroller controls the distance sensor SRF05 and using sensors Mq-7 as CO gas detection sensors. when the robot detects the presence of dangerous gas levels at line 1 meter of gas quickly detected by the ADC value 655 with a time of ± 2 seconds. When the robot detects the distance that close large value while the gas will be detected at a much travel time value of the detected gas will decrease. Keyword: Arduino Uno, Sensor SRF05, Sensor Mq-7, Motor DC. KAT
