SpecMy job, as an undergraduate EE student, is to create a test rig for offsite electronics (environmental sensors hooked up to a data logger, 12V batteries and solar panels). The test rig should be able to evaluate output from sensors (serial TTL, analog voltage, 1-wire) and output required signals (TTL, voltage, pulse, 1-wire) that could be supplied to the data logger to test wiring connections, logger analog inputs, relays, etc.
For example, we are getting incorrect data from an ultrasonic sensor (MB7380) operating on TTL. I do not know if the sensor is outputting the correct signal, or if the logger is not reading the sensor correctly. The test rig should eliminate this problem, and help with QA/QC during fabrication.
At first I thought about using a DSO203 Pocket-Sized Oscilloscope which can also output 10Hz to 8MHz. (Datasheet here.) Although, I do not think that could evaluate the 1-wire thermometer--and it seems my adviser (not an EE) wants something more user friendly to the average Joe. I mean, it seems that I am supposed to create another PCB board with various probes and green and red LED pairs for good or bad (for each type of sensor).
What do you think? What would you do? My adviser has not given me any other requirements.
