Description

The DS18B20 Waterproof Digital Temperature Probe is designed for precise, non-corrosive liquid and environmental temperature monitoring. Unlike low-cost clones that suffer from frequent signal dropouts or calibration errors, this probe incorporates an Original DS18B20 Silicon Chip encapsulated within a durable, moisture-resistant stainless steel tube sealed with high-thermal-conductivity epoxy resin.

Utilizing Maxim/Dallas Semiconductor’s proprietary 1-Wire protocol, the sensor converts temperature readings directly into a digital signal (9 to 12-bit configurable resolution), eliminating signal degradation over long cable runs. The 1-meter flexible black cable is insulated with PVC, making it simple to deploy in remote, underwater, or outdoor sensing nodes.
