Introduction

This is a

waterproofed

version of the

DS18B20 Arduino

Temperature sensor

(https://www.dfrobot.com/product-689.html). Handy for when you need to

measure something far away, or in wet conditions. While the sensor is good up

to 125℃ the cable is jacketed in PVC so we suggest keeping it under 100℃.

Because they are digital, you don't get any signal degradation even over long

distances! The DS18B20 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.Usable with 3.0-5.5V systems. Because

each DS18B20 contains a unique silicon serial number, multiple DS18B20s can

exist on the same 1-Wire bus. This allows for placing temperature sensors in

many different places. Applications where this feature is useful include HVAC

environmental controls, sensing temperatures inside buildings,equipment or

machinery, and process monitoring and control.
