The Sonbest SLST1-9 is a digital temperature sensor based on the Dallas Semiconductor DS18B20 chip, housed in a thin‑walled stainless‑steel tube (0.15 mm) with IP67 protection. It uses a 1‑Wire bus interface for reliable, low‑cost communication and offers high sensitivity with minimal temperature lag.
The manual provides installation instructions, technical parameters, pin definitions, and ordering information. Key specifications include a measurement range of –55 °C to +125 °C, ±0.5 °C accuracy, 9.42‑bit resolution (0.0625 °C), 750 ms conversion time, and a power supply of 3 V‑5.5 V. The sensor can be mounted with an M10 thread and customized lead lengths up to 100 m.
