1- Draw a basic circuit to make use of a photoreceptor (your choice, photovoltaic, photoresistor, ect.) to turn a light off when daylight hits the sensor.
2- Draw a strain gauge circuit and its external components to attach to a conveyor mounted only at the ends to measure the load at the center of the conveyor. What type of testing would you need to do to establish a baseline and calibration curve for this sensor?
3-What is an open collector input why is it used on sensors.
4-List three types of vibration sensors and discuss how they operate.
