Compare and contrast at least three sensors. 1 page limit for description . 3 paragraphs Figures must be used Use sparkfun, omega, adafruit to find the sensor (or others if you find sensor systems) Write about the problem, how will you solve it, and what the solution will do for you Make sure to review more than one type or part of sensor and justify the selection You will be graded in your writing. Concise writing only, no fluff .State the price, specs, manufacturer and part number Due Sunday (7/15/2018) 5:00 PMExplanation / Answer
Sensors can be used for this purpose is 1. Infra red sensor,2. Ultrasonic or sonar distance measuring sensor 3. Capacitive proximity sensor, .
1. Infrared sensors consist of two LED like structures one transmitter another receiver. The transmitter transmits infra-red energy. The reciever collects it. Whenever the receiver collects signifacnt amount of energy it turns ons the signal processing cicuit.
2. Here the refelcted sound waves are detected.
3. Capacitive proximity sensors can be used for plastic door-frames.
Ultrasonic sensors are, for the most part, completely insensitive to hindering factors like:
Brighter surfaces are easier to detect for Infrared than dark surfaces, as the sensor doesn’t detect darker surfaces. Infrared sensor values normally fluctuate in variant light conditions.
