Features

• Description
• This sealed digital temperature probe lets you precisely measure temperatures in wet environments with a simple 1-Wire interface. 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. Power for reading, writing, and performing temperature conversions can be derived from the data line itself with no need for an external power source.
• Beca*** 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 ***ful include HVAC environmental controls, sensing temperatures inside buildings, equipment or machinery, and process monitoring and control.
• Note:The pinout for this sensor is as follows:RED=Vcc BLACK=GND WHITE=SIG
