RANCANG BANGUN VENTILASI RUMAH OTOMATIS MENGGUNAKAN SENSOR ASAP SENSOR MQ-7 BERBASIS ARDUINO UNO

Abstract

Smog is a serious problem and occurs almost every year in Riau Province. This smog occurs due to forest and land fires (Karhutla). Based on data obtained from the Directorate of PKHL, Ministry of Environment and Forestry of the Republic of Indonesia. The method of making this tool is to design an automatic ventilation device in which there is already a filter. The filter is made with bagasse which was previously dried in the sun for approximately a week, after drying the bagasse in the oven for approximately 6 hours. After being in the oven, the bagasse which has become charcoal is also activated with a KOH solution until the washing process is carried out using Aquades and then in the oven again to dry it. After the filter is finished, the filter is placed in an automatic ventilation device that has been designed. Air will enter through the ventilation if the air content is categorized as good, or the level is below 25 ppm. Ventilation will be closed if the air content is poor, or above 25 ppm. When the air is bad, the fan will activate and channel the air into the filter chamber. Based on the results of the study, the air entering the filter room managed to filter the air well.
