Cảm biến nhiệt độ DS18B20 chống nước

INTRODUCTION

If you are familiar with our product, you will find there is waterproof temperature sensor named DS18B20. This waterproof temperature sensor kit is using the same probe——DS18B20 probe AS . It contains a probe with a resister module. So it is easy to connect on the Arduino board. 

The DS18B20 temperature sensor provides 9 to 12-bit (configurable) temperature readings over a 1-Wire interface, so that only one wire (and ground) needs to be connected from a central microprocessor. Compatible with 3.0-5.5V systems.
