Hi friends, i have 3 sensors which i can get accurate readings until i wire another tempreature sensor.
Even if i connect its GND pin to Arduino, results become inaccurate.
Grumpy_Mike suggested me to use 0.1uF decoupling capacitors and gave me a link (some schematics and explanation) about it. I think i understand how to use but i am not sure and i don't want to burn another circuit anymore

Can you please tell me how to use this capasitors to prevent inaccurate readings?
By the way thanks to Grumpy_Mike because of his great help.
Thanks
