I am trying to do a project where I have three different ultrasonic sensors fitted at three different places of my house and I have one Raspberry Pi. I cannot use the normal jumper wire since they are very small in length. Can I use normal line wires to connect those sensors to my Raspberry Pi? If not which type of wires should I use?
Actually the longest distance between one sensor to the Pi 3 is about 15m. Will there be any problem within that distance? Also is there any way of transferring sensor data from sensor to Raspberry Pi over WiFi without physically connecting them?
So can data be transferred over that distance(10-15 metres) without loss?
First - rather than relying on anecdote and opinion in an online forum, read the datasheet or specifications of the sensors you are trying to connect to determine the design limits of the signals they send and receive.
Second - maybe an alternative - put an RPi and a sensor on your 'workbench', connect them with 15 metres of 'normal line wire' and see it it works.
Puzzled by this:
is there any way of transferring sensor data from sensor to Raspberry Pi over WiFi without physically connecting them?
Using WiFi would not involve physically connecting them. But if the sensors already have WiFi why not just use it?
