Monitoring Design of Temperature and Humidity Issues in IoT-Based Train Passenger cars

The temperature condition of the training room is very important to provide good service for train service users, when the train is owned by PT. INKA often gets complaints in the form of temperature increases. The increase in temperature can be influenced by many factors, namely the level of train passenger density that exceeds the cooling capacity of the AC unit and some passengers who change the temperature of the AC via their Android/smartphone device. Besides that, the changing temperature conditions in the train room triggered damage to the air conditioner itself. A real-time air temperature monitoring system is needed in monitoring the air temperature inside the train. The Internet of Things is a very promising scientific development for optimizing daily needs based on smart sensors and smart tools that work together through the internet network. In the results of the experiment, the lowest temperature was at 08.00 with a temperature of 18C which was declared cold because the temperature exceeded the low temperature limit of the standard provisions for thermal comfort based on SNI 03-6572-2001, namely the temperature was below 20,50C or less than 20,50C, while the highest temperature at 13.00 with a temperature of 30C it is declared hot because the temperature exceeds the high temperature limit of the standard provisions for thermal comfort based on SNI 036572-2001, namely the temperature is more than 27,10C.
