Earners of the Electronic Sensors and Devices badge have developed the skills necessary for understanding the fundamentals of electronic sensors and devices. They've learned components, features, functions, applications, and troubleshooting of sensors, tranducers, thermocouple meters, varistors, zener diodes, thermistors, detectors, attenuators, and transmitters. They've studied the types, importance, and operation of oscilloscopes. They've explored forms of modulation and demodulation.
