Rancangan Monitoring Sirkulasi dan Stabilitas Suhu Ruangan Menggunakan Sensor Gas dan Sensor Suhu dengan Tampilan Pc Berbasis Atmega 8535

Abstract

This research is aims to circulate and stabilize the temperature to keep them clean and detect C02 in the model room. This system was developed using a monitoring plan that comes with Microcontroller ATMEGA 8535 as the central control of the entire system. This system includes several devices such as temperature sensors (LM-35) as a measure and control the temperature there is around. The system has two sensors are temperature sensors to detect air at room temperature and gas sensors to detect if there is interference or excessive concentration of gas in the room. The temperature of sensor has been tested, and the sensor will detect the temperature in the room, if the detected temperature exceeds the maximum temperature is set, then the fan will automatically turn on to cool the room if the temperature has returned to normal, then the fan will die. For a gas sensor, the sensor will detect gases harmful to humans, especially CO2. If the concentration of CO2 is already too much then the system will automatically activate the motor to open the vents, while the fan will work to suck air containing harmful gas to be released out of the room. PC serves to determine the status of the sensor system conditions. The resulting system produced measures the temperature of 30oC – 36oC with output voltage of 300 mV - 360 Mv. The temperature sensor (ICLM35) and gas sensors (MQ-2) was tested will work automatically if detected in accordance with the specified.
