What is the difference between ds18b20 and ds18s20

If we match the sequence on the data sheet, we get that the middle pin white is the data and the third pin red is the power. Am I going to hurt anything if I try this?

Measures temperature in mS. Thank you for that. I tried having both data sheets up in front of me, but got lost trying to find the difference.

I think I will assume, given the ability to function with "parasitic power," that reversing the data and power leads will not cause harm.

It just won't work. That could be enough to have caused damage. I meant that I would assume the shield is ground. Then I would put 5v on one pin and data which is a 5v signal on a digital pin. Then, the data input to the sensor would be getting either a constant 5v, which it would expect when used in "parasitic power" mode, or a 5v data signal which it expects.

Either way, should be no harm done. The other pin power would be getting the opposite - a 5v data signal which should appear like noisy power and cause no harm, or a constant 5v, which it expects.

Seems safe to me. Now, that means there are 6 different ways to hook this up. Log in Register. Search titles only. Search Advanced search…. New posts. Search forums. Log in. For a better experience, please enable JavaScript in your browser before proceeding.

DS18B20 v DS Thread starter stocky Start date May 24, I knwo there is a difference - ie programmable resolution vs non-programmable I guess I cant use a DS instead of a DS18B20 then :- Anyone say different? Sorry Mate.

Man 2 page "Note the readtemp command does not work with the older DS or DS18S20 as they have a different internal resolution. Guess what i have heaps of and NONE of You can get 0. Good find! See also the Prof. Last edited: May 24, Cant use Readtemp on Pin 3 of an 08M! Last edited: May 25,
