naperlou; I was puzzled that the two heaters were not balanced, but I wouldn't have found that out if the overheat hadn't tripped. I contacted the manufacturer several times (e-mail) during the process. I don't know if it caused them to review their design.
You can only hope the feedback to the manufacturer prompted their engineers to make changes, Glann. Not necessarily, though. Let's hope that the move toward social media in design will help the feedback loop reach the design function.
GlennA, normally we are deploying multiple sensors at different places and average of the sensor values are accounted for decision making. Even most of such devices are equipped with more than one sensor for better accuracy. In such cases these types of failover can be minimized.
The design constraints were composed by someone with no experience building such a room. I was told the PLC would only have to monitor the room temperature and relative humidity - the air conditioners would use their internal sensors for temperature, and dehumidifying was assumed to be included.
I remember a saying I was told years ago: Do you know the best thing about beating your head against a brick wall ? It feels so good when you stop. I stopped worrying about the parts of the project that I had no input on or control over.
Engineers at Fuel Cell Energy have found a way to take advantage of a side reaction, unique to their carbonate fuel cell that has nothing to do with energy production, as a potential, cost-effective solution to capturing carbon from fossil fuel power plants.
To get to a trillion sensors in the IoT that we all look forward to, there are many challenges to commercialization that still remain, including interoperability, the lack of standards, and the issue of security, to name a few.
This is part one of an article discussing the University of Washington’s nationally ranked FSAE electric car (eCar) and combustible car (cCar). Stay tuned for part two, tomorrow, which will discuss the four unique PCBs used in both the eCar and cCars.
