DS18S20 temperature keeps jumping with owget

Rainer Dorsch

Hi,

 

I am wondering if anybody has seen this before: When I read temperature from a DS18S20, the value keeps jumping:

 

root@mohot:~# owget /10.67C6697351FF/type

DS18S20root@mohot:~#

root@mohot:~# owget /10.67C6697351FF/temperature

35.5571root@mohot:~# owget /10.67C6697351FF/temperature

36.9438root@mohot:~# owget /10.67C6697351FF/temperature

87.643root@mohot:~# owget /10.67C6697351FF/temperature

25.6785root@mohot:~# owget /10.67C6697351FF/temperature

65.7137root@mohot:~#

 

Any hint is welcome.

 

Many thanks

Rainer
