Help With a design Help With a design littlechef (Chemical) (OP) 10 Apr 15 04:22 We are trying to make a wifi enabled, Waterproof, sensor that can read the following and transmit to a Ipad or computer for constant monitoring: PH Levels Temperature Yeast Counts Degradation of yeast The sensor needs to be disposable and link up in an incubator (sterile environment). Any help would be great. RE: Help With a design IRstuff (Aerospace) 10 Apr 15 06:27 Is this for school?

I can do anything. I can do absolutely anything. I'm an expert!

So, no probs. Yeast Counts and Degradation of yeast seem to be very specialized measurements. ABER is doing something similar for bioreactors - have you been in touch with them? The rest seems to be packaging and WiFi, ZigBee or some other IoT application. Fairly standard. Gunnar Englund www.gke.org -------------------------------------- Half full - Half empty? I don't mind. It's what in it that counts. RE: Help With a design djs (Electrical) 10 Apr 15 18:13 I would think that the sensor for the yeast would depend upon what medium that the yeast is in. For example if the yeast were in air or water a particle counter might work.
