The team had a breakthrough this week by mounting the fully integrated RFID system and ultrasonic sensors to the doorway. This system is successfully able to detect the movement direction, the room, and the identity of one tagged object! Additionally, a printed circuit board concept was created to simplify the organized mess of our system. The mechanical engineers can now re-design the RFID antenna housing to accommodate the printed circuit board. With our ultrasonic sensors now functioning as intended and with the proven success of our system at reading one RFID tag at a time, the team has an exciting prototype to demonstrate to the judges at Prototype Inspection Day 2 on April 1st.

Further tuning will be made to the RFID reader power and the ultrasonic sensor sensitivity to allow for multiple tags to be detected and logged in our database. A housing system will be made to improve the wire management on the RFID reader. After overcoming our roadblocks with the ultrasonic sensors, the team has garnered the momentum needed to deliver a fully functioning product by the final design review. Go Gear Guardians!
