I am building a processing for a university project and am looking for some recommendations of components that will work well with the NI USB-6009. Due to this being a university project my budget is $100 and I require the following components:
a float switch or something similar
a two-way or three-way solenoid valve
a pump
a pH sensor
a temperature sensor
a camera
I understand that I may not have a sufficient budget for all of these components but any recommendations of products would be appreciated.
