Description
DS18S20Z is a 1‑Wire digital temperature sensor in the DS18S20 family from Maxim/Dallas. It measures ambient temperature from −55°C to +125°C with 9‑bit resolution (about 0.5°C steps). It communicates on a single data line (plus ground) and can be powered parasitically from the data line or from a dedicated supply. Each device has a unique 64‑bit ROM code, so many sensors can share one 1‑Wire bus. Temperature is read via the scratchpad memory after issuing a conversion on the bus. It’s easy to use with microcontrollers and is supported by common libraries (e.g., OneWire, DallasTemperature for Arduino; 1‑Wire on Raspberry Pi). Typical applications include hobbyist temperature sensing, data logging, HVAC, and environmental monitoring. Note: DS18S20Z is a variant/branding of the DS18S20—check datasheet for exact packaging and power options.
