방수 DS18B20 고온 온도 센서 -3미터
(High Temp Waterproof DS18B20 Digital Temperature Sensor - 3m long)
개요
- 본 제품은 방수가 되는 DS18B20 고온 센서입니다.
- PTFE 재질 와이어가 장착되어 있으며, 센서의 최대 측정온도인 125도까지 사용이 가능합니다.
- 센서 출력은 디지털 출력이기 때문에 와이어 길이가 길어서 발생하는 데이터 손실이 없습니다.
- 3-5V 시스템과 사용이 가능합니다.
- Dallas 1-wire 프로토콜을 사용합니다.

문서
- You'll need a 4.7k resistor which is required as a pullup from the DATA to VCC line when using the sensor. Here's a CircuitPython/Python guide for these sensors. We don't have a detailed Arduino tutorial, but you can get started by using the Dallas Temperature Control Arduino librarywhich requires also the OneWire Library.
