| Mar 18, 2023 at 19:19 | comment | added | Martel | @andyaka If my understanding is correct, a hall-effect sensor is a device with a hole through which I can pass the wire I want to sense, and then get an ouput of 0 to a few volts (less than 3, depending on the current going through the wire) on one of its pins. That seems safe and within my grasp, am I wrong? | |

| Mar 18, 2023 at 18:55 | comment | added | Martel | @DDuck I could, however if I could learn how to actually be able to sense current that would be greate for me. | |
| Mar 18, 2023 at 18:51 | comment | added | Martel | @Andyaka I didn't know the existence of those, thanks. It turns out there is a YouTube video in which a person does exactly what I want with a current transformer: youtube.com/watch?v=Z3YSHhS39Bc However, this seems pretty unsafe given my lack of experience and taken into account I would like this 'mechanism' to be connected 'all the time', without supervision. (I mean, because of the burden resistor) | |
| Mar 18, 2023 at 18:49 | comment | added | Martel | @justme The purpose of sensing is just to display the information somewhere. With regards to the socket with LED, good point, I didn't realise it. That discards that option. It's true as well that any adaptor between the socket and the heater is another point of failure, but given that's not 'home-made', I would expect it to be pretty safe. | |

| Mar 18, 2023 at 14:43 | comment | added | Justme | What is the purpose of sensing? If you have such an socket adaptor with a lamp/LED, it only tells if the socket adapter has power, it does not know if the heater is even plugged in or if the fuse has blown, and heater has a thermostat so it will also don't always consume current but only when heating. And you don't have to break the LED out, you can just sense the light. But any adapter or wiring between 2kW heater and socket is just extra point of failure that can heat up and burn your carpet if it can't handle current. Typically it is recommended to not use any extension cords. | |
