So, recently I’m using flame sensor to make a project, and it requires a lot of sensor. I found not enough port for vcc and gnd, so I connect one port to a breadboard and share it with all the sensors I added.
Here are the sensors I have:
2 flame sensors
Would it make my fire sensor imprecise?
That's fine. In fact, that's what breadboards are for!
The accuracy in terms of sensitivity and selectiveness of your project will depend on many factors; the breadboard itself plays a role in this as well, but it will be very low on the list.
More relevant to consider are things like the distance between the sensor and the location of the flame, the presence of other source of IR radiation that can be misinterpreted by the sensor as a 'flame', the sensitivity/threshold setting on your sensor boards, etc.

Which Arduino are you using?
Many have sereral 5V and GND connections, so a breadboard might not be becessary
For example the Uno has Four pins for 5V and Five GND connections
I’m now using Mega 2560, and I got some other sensor and a l9110motor that makes me ran out of ports, so I decided to connect it all to single one
Yeah I know the condition is important, but the thing is when I use the picture below to modify one sensor, the others would all change
And also, when the motor connecting on the same breadboard moves, it will also change the attributes
Setting the sensitivity of the sensor using the potentiometer you have circled in the picture will only affect that specific sensor boards. The others will not be affected. If you do see a difference in the readings of all sensors if you adjust the sensitivity on one of them, there's either a hardware problem or a software bug.
Ah, so there's a motor, too. If you want to troubleshoot these problems, please post a schematic of your entire system as well as a good photo showing clearly how everything is connected.
My first thought is that you probably have a power supply issue causing a voltage drop when the motor is running, due to the supply of the sensors and the motor supply being insufficiently (or not at all) decoupled from each other.
Yeah true, I do think it’s power supply problem, but I can’t actually measure the current or voltage on such a small board. I’ll send you the schematic in few days
Ok, so ummmm, I found 1 of my flame sensor warmer than others, probably it’s bc of that
