Temperature sensor SD18B20 2m cable

This is a 1-wire temperature sensor in a waterproof stainless steel package, with a two-meter long cable. The DS18B20 uses a unique single-bus interface - a single data line carries both power addressing and temperature readings between many sensors and a controller, so you can chain several probes onto the same wire without extra components or dedicated wiring per sensor. That makes it a popular choice for multi-point temperature monitoring, from outdoor weather stations to equipment enclosures.
