| Summary: | Home security has become a prime concern in recent years. As technology is emerging every second, abundant IoT-based smart surveillance systems have been developed and implemented with many modern features to keep the home safe. The proposed project is an extended approach to the existing home security system. The project aims to reduce false alarm rates of the existing home security system by using a Dual Technology motion sensor. Dual-technology sensors are sensors that combine two different types of technology. The dual-technology sensor uses both PIR and ultrasonic sensors, activating the trigger only when both sensors detect any motion of an object. The proposed setup effectively reduces false alarms caused by inanimate objects. The trigger caused by the Dual Technology sensor sends a message alert to the specified phone number through the Twilio Programmable Messaging API. Ultrasonic technology is sensitive to motion toward and away from the detector; passive infrared technology (PIR) is sensitive to motion across the field of view. The future implications of the project are great as it can also be used in the Automation of lighting in homes, offices, and libraries.
