    An Efficient FSR-based Approach for Self Notifying Chairs to Minimize Long Duration Sitting Postures
    (Institute of Electrical and Electronics Engineers Inc., 2023) Sarangam, K.; Appala, T.; Vani, B.V.; Sai Kumar, A.S.
    The basic principle of a force sensing resistor is that the resistance decreases with increase in force. This property of the sensor can be used to find its application on many devices and circuits. In this research paper, a FSR is used to find whether a person is sitting on a chair without change in position for too long. The creation of a straightforward tool to track a user's sitting time and issue a warning if it exceeds a predetermined time limit is described in this proposed work. To save the user the trouble of lugging it, the tool was installed on a chair. As experts say, every 20 minute a person should change his/her posture so as to maintain good health. A circuit is developed in order to acquire the change in signals from the FSR. In order to construct a user-friendly display, LabVIEW software was employed. It is anticipated that the user will be able to spend less time sitting down by using the tool. © 2023 IEEE.

    An Efficient Smart Gas Detecting System using MQ9 Sensor
    (Institute of Electrical and Electronics Engineers Inc., 2023) Reddy, B.N.; Appala, T.; Vani, B.V.
    Gas Detection System is most important system in any buildings. Now a days in factories so many poisonous gases are emitted from reactions especially in chemical factories it will helps to detect the presence of gas particles and the amount of spreading in air. Not only in factories other institutes, buildings, colleges etc especially it will detect the presence of fire and it will give an alert. Very minor leaks and their location can be found using visual inspection or portable detectors, but the detection process takes a very long time. In this paper, we developed system with MQ9 sensor which detects the poisonous gases like carbon monoxide, LPG gas etc. This proposed technique includes a buzzer alerting system that beeps repeatedly until the gas detection module fails to detect the gas in the surroundings. © 2023 IEEE.
