We have ✅ 3 available of the SF-SEN-18367 in our Sydney warehouse.

Express post delivery (2-5 business days)

A sealed, waterproof DS18B20 digital temperature probe for precise measurements in wet or harsh environments. The sensor communicates over a 1-Wire interface, requiring just one data pin (plus ground) to connect to your microcontroller. It can even be parasitically powered from the data line.

Each DS18B20 has a unique silicon serial number, so multiple probes can share a single 1-Wire bus — ideal for multi-point temperature monitoring in HVAC systems, equipment, and process control.
