STMS – Surface Temperature Monitor Surveillance

1-wire system

1-Wire is a device communications bus system designed by Dallas Semiconductor Corp. that provides low-speed data, signaling, and power over a single signal. It is typically used to communicate with small inexpensive devices such as digital thermometers and weather instruments.
