hello, i have problem with using this sensore, sometimes when power on arduino the display show me -27°c( -127°C but i am using 7 digit numbers with only 2 numbers) if i reconect only the sensor power it work but after some times it show back, i am using 2 sensors trying change pull up from 4k7 to 2k2 and also capacitor 100uf between gnd and 5v, but i am still geting the problem. when iam using the 4k7 on both sensors the problem show only on OUT sensore with about 1 meter added cabels, but after 2k2 and capacitor the problem start sometimes OUT sensore and sometimes both or only IN sensore. maybe is problem with code or the sensor dont have enough time to read and send the data. i am trying also get temp by adress with adres of the senrsor and sometimes i cant get the addres from the sensor, but all is soldered together, i checked it two times for cold connection .as power i use car 12V with step down module about to 12->7.5 volst to dc jack. can someon help me pleas? sorry for my english if any problem to understand.
