MS-TPD - Temperature and Flow Sensor 1-Wire Pins one (ground) and three

Pins one (ground) and three (Vdd) of the DS18B20 are connected together internally

converting TTL input signals to ASCII output

The responsive touch surface relays the 16-digit address through the device to your computer when it is in full contact with the iButton®

The iButton® Memory Typer™ is part of the iButton® Typer™ family

MS-TPD - Temperature and Flow Sensor 1-Wire Pins one (ground) and threeThis sensor measures temperature using a DS 2438Z with an operating range of 40C to +85C. It is not calibrated, but empirical data proves it to be accurate within a few degrees of actual temperature. The sensing device is partially enclosed and mounted to the rubber tubing attachment, so the time to respond to temperature change will be relatively slow. The sensor should not be placed in direct sunlight, as the radiant heat will become trapped inside
