there is some doc here (french ...) http://z-graphix.com/linux/temperature/howto.html what bugs me, is 1- how do you manage multiple sensors without using one rs232 per sensor or a way to connect with something else (like rj45/lan or usb; i want to use an old box which has 2 rs232 both used and 4-ports serial card seems not really cheap) above link has some part for usb but seems there is not all details. 2- how to manage sensor on distance > 10-20m: radio, wifi, ... thanks Regards Julien
