18B20 Sensor - Flat 50cm

This is a flat probe version of the DS18S20 Temperature sensor. The sensor has a 20 x 7.5 x 3.5mm flat plate with allowing for more surface area .Handy for when you need to measure something far away, or in wet conditions. While the sensor is good up to 125°C the cable is jacketed in PVC so we suggest keeping it under 100°C. Because they are digital, you don't get any signal degradation even over long distances! The DS18S20 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 DS18S20 contains a unique silicon serial number, multiple DS18S20s 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.With our plug-able terminal, there is no soldering required to connect to our IO Expansion Shield.
