    Optical Sensors Essay

    • 990 Words
    • 4 Pages

    In today’s world sensors especially optical sensors have many emerging applications beginning from the medical diagnostics to detect the pollution in the environment. Because of these wide range of applications the challenges faced to design, proper functioning and maintenance of an optical sensor requires immense knowledge of optical, material, and environmental properties that could affect sensor performance in all aspects. The wavelength range of the laser, interactions between the signal and the target, the effect of the environment on the transmission of the signal, methods used to amplify the optical signal, and materials which are used to focus on and collect the optical signal are all important aspects of optical sensors. This report…

    1.1.1 Types of Sensor Networks Terrestrial WSNs: - In Terrestrial WSNs, nodes are distributed in a given area either in a pre-planned manner (sensor nodes are placed according to optimal placement, grid placement, 2-d and 3-d placement models) or in an ad hoc manner (sensor nodes are randomly placed in the target area by dropping it from plane). After all battery power is limited and it cannot be reenergized, terrestrial sensor nodes must be provided with a maximum power source such as solar…

    The Importance Of Sensors

    • 1321 Words
    • 6 Pages

    A sensor is a device that receives a stimulus, meaurand, or any input signal such as from heat, pressure, light, motion and many more, and responds with an electrical signal. This electrical signal then will decide what will be the result of an output. Depending on the input of the stimulus, the sensor will react to it in a particular way. Sensors are attached to an electrical device and they scan the surrounding environment. Then it converts the input signals to a voltage, current or charge.…

    This mechanism implemented with two sesnors which can detect a surface under the robot and move the robot accordingly. If the edge is detected on a platform by right sensor the robot will turn to its left and vice versa. When the robot detects the edge on both the sides it moves backward untill it doesn’t detect any edge and then moves to the right side a little and repeats the above process. Line following robot : Now, lets design a line following robot, for that, I need to pick a 50 ext block…

    The communication protocols used in connecting sensors form a network for collecting sensory information called BSN. Patients who are going about their day to day activity can receive quality health monitoring in real time by us of BSN. The BSN nodes are attached to these patients. On a predetermined period, the BSN collect health information such as pulse, blood sugar level and temperature and transmit it to a remote medical aid. This way, the medical personnel are able to keep up to date with…
