What is This Sensor? Answers to Your Questions

AI Thread Summary
The ceiling sensors in question are hydrogen sulfide detectors, designed to monitor gas levels in bathrooms and laundry rooms. They feature a 6-inch metal rod and resemble smoke detector frames but serve a different purpose. When hydrogen sulfide levels become too high, these sensors trigger the fire sprinklers as a safety measure. This system provides an early warning to prevent hazardous situations. Understanding the function of these detectors is crucial for safety in college facilities.

Sorry I don't have a picture right now. But this has had me wondering and I can't find anything online about it. In my college in all the bathrooms and laundry rooms I see these sensors in the ceiling which is just a 6" metal rod hanging. There are your regular smoke detectors and everything on the ceiling and then there are these things and I don't know what in the world they do. It just looks like your regular smoke detector frame with nothing but a metal rod hanging down.

It's a hydrogen sulfide detector. If levels get too high near the ceiling, the fire sprinklers activate. You are forewarned...
 

Thread 'How might electronics be different if AC voltage was 72V at 45 Hz?'

Hey guys. I have a question related to electricity and alternating current. Say an alien fictional society developed electricity, and settled on a standard like 73V AC current at 46 Hz. How would appliances be designed, and what impact would the lower frequency and voltage have on transformers, wiring, TVs, computers, LEDs, motors, and heating, assuming the laws of physics and technology are the same as on Earth?

Thread 'What happens if shielded cable has a short to the shield?'

While I was rolling out a shielded cable, a though came to my mind - what happens to the current flow in the cable if there came a short between the wire and the shield in both ends of the cable? For simplicity, lets assume a 1-wire copper wire wrapped in an aluminum shield. The wire and the shield has the same cross section area. There are insulating material between them, and in both ends there is a short between them. My first thought, the total resistance of the cable would be reduced...

Thread 'Why does the amperage go real high if there is a low voltage short?'

I used to be an HVAC technician. One time I had a service call in which there was no power to the thermostat. The thermostat did not have power because the fuse in the air handler was blown. The fuse in the air handler was blown because there was a low voltage short. The rubber coating on one of the thermostat wires was chewed off by a rodent. The exposed metal in the thermostat wire was touching the metal cabinet of the air handler. This was a low voltage short. This low voltage...
