Abstract

The development of technology in the digital era has a significant impact in various fields including home security. The existence of conventional door locks that are easily broken into and the risk of losing physical keys raises the need for a more sophisticated security system. This research aims to design an Internet of Things (IoT)-based home door security system that utilizes the Telegram application as a remote control medium. The system integrates a fingerprint sensor, keypad, and push button to open and close the door. Passive Infrared Receiver (PIR) sensor and ESP32-CAM to detect motion and take pictures that are sent to Telegram. In addition, the system is equipped with an Uninterruptible Power supply (UPS) to ensure the device remains operational during a power outage. The results show that the electronic door lock system works well. The motion detection system is also able to accurately detect activity around the door and send images to Telegram with a fast response time. In addition, the use of UPS to keep the system functioning despite the interruption of electricity supply proved to be effective. Based on the test results, it can be concluded that this IoT-based home door security system is effective, easy to use, responsive, and continues to function despite a power outage

Abstract

Waste management is one of the common issues faced by many cities worldwide. Many people dispose of waste carelessly, failing to separate different types of waste, leading to piled-up and scattered garbage. This problem is caused by a lack of public awareness about environmental preservation and the absence of quick access between garbage bins and waste collectors, resulting in waste accumulation. Based on these issues, a smart trash bin based on the Internet of Things was designed using NodeMCU ESP32 as its microcontroller. The bin lid operates automatically using an infrared sensor as an object detector and is equipped with a DFPlayer module that can produce sound. The waste separator uses three proximity sensors and a DHT22 sensor to differentiate between wet organic, dry organic, and inorganic metal and non-metal waste. In this study, a trash bin was also designed with an ultrasonic sensor to detect the bin’s capacity, and the data was then sent via the Blynk platform, allowing waste collectors to access it through a smartphone. From the test results, the three proximity sensors and the DHT22 sensor successfully differentiated between wet, dry, metal, and non-metal waste. The data obtained by the ultrasonic sensor was also successfully transmitted to the collectors via the Blynk application
