Briefing Sensor Lab Elevator Instrumentation Circuits & PSPICE Radio

Sensors A Sensor is a device which responds to a certain stimulus 2 Main Types of Sensors Digital and Analog Digital- on or off Analog Sensors can read different input values Analog Sensors must be consistent and show exhibit a linear pattern for different stimulus values

Analog Sensors Optical Range Finder: Returns a value based on the distance the sensor is from something Light Sensor: returns a value based on the amount of the light the sensor detects Ultrasonic Range Finder: uses sound to detect the distance the sensor is from an object

Elevator Goal: Construct an elevator which goes to two different floors and stays at these floors when corresponding buttons are pressed Sensors were a requirement for this project The Construction of the elevator had to be logical because the motors had limited power and the Lego's easily caught on each other

Our Elevator Design

Programming Elevator Efficiency- Although this elevator only had two floors the program needed to allow itself to be expanded Adjustment of power of engines based on construction of elevator Using Sensors to create a system to control the elevator

Instrumentation Lab Objective: The application of an oscilloscope is to measure the voltage of different signals. Signals: D.C. vs. A.C. DC Power Supply: generating voltage from -25v to 25v.

Circuits Lab What we did: Built circuits and tested voltages Found voltages across resistors Tested Diodes Why we did it: Learned how to analyze and evaluate circuits. Series and Parallel Learned about most basic circuit (resistor circuit). Learned about Ohms Law Learned about Diodes
