An IoT solution to detect sit - in and stand - up from a chair, in a connected sensor network using ESP8266 boards.
Its a common requirement to detect the empty seats within a facility in various scenarios, whether it be an auditorium or an home care facility. The applications are limitless. But the manual or current web based solutions has various limitations and they cannot be extended beyond a few hundred seats. This study explores the MQTT based IoT implementation, which helps to sense the engaged seats, which are replicated using pressure switches, and sends the data to a web server through a bridge node. MQTT enables the data transfer even if the communication has high latency and low bandwidth, and gives a real time feedback to the server to track the changes in the seat positions immediately. This helps to establish a robust system with the capability to be expanded to any capacity requirement.
