This sensor uses the one wire protocol to talk with the microcontroller. Here, we will show how to use the waterproof temperature sensor (DS18B20) with your Arduino. Stainless steel tube 6mm diameter by 30mm long.Applications where this feature is useful include HVAC environmental controls, sensing temperatures inside buildings,equipment or machinery, and process monitoring and control. This allows for placing temperature sensors in many different places. 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.īecause each DS18B20 contains a unique silicon serial number, multiple DS18B20s can exist on the same 1-Wire bus. While the sensor is good up to 125☌ the cable is jacketed in PVC so we suggest keeping it under 100☌. Handy for when you need to measure something far away, or in wet conditions. This is a waterproofed version of the DS18B20 Temperature sensor.
