Tempeature Sensor

Product DescriptionThis Maxim-made item is a digital thermo probe or sensor that employs DS18B20. Its unique 1-wire interface makes it easy to communicate with devices. It can converts temperature to a 12-bit digital word in 750ms (max).Besides,Website:, it can measures temperatures from -55°C to +125°C(-67F to +257F). In addition, this thermo probe doesn't require any external power supply since it draws power from data line. Last but not least, like other common thermo probe, its stainless steel probe head makes it suitable for any wet or harsh environmentFeature: 1:Power supply range: 3.0V to 5.5V 2:Operating temperature range:-55°C to +125°C (-67F to +257F) 3:Storage temperature range:-55°CC to +125°C (-67F to +257F) 4:Accuracy over the range of -10°C to +85°C:±0.5°C 5:3-pin 2510 Female Header Housing 6:Waterproof Stainless steel sheath 7:Stainless steel sheath 8:Size of Sheath:6*50mm 9:Pin Definition: RED:VCC      Yellow:DATA       Black:GND Package Contents:   1m Digital Thermal Sensor DS18B20*10Application:The DS18B20 Digital Temperature Probe provides 9 to 12 bit (configurable)  temperature readings which indicate the temperature of the device. Information is sent to/from the DS18B20 over a 1Wire interface, so that only one wire (and ground)needs to be connected from a central microprocessor to a DS18B20. Power for reading, writing, and performing temperature conversions can be derived from the data line itself with no need for an external power source.Because each DS18B20 contains a unique silicon serial number, multiple DS18B20s can exist on the same 1Wire 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.NTC Temperature Sensor Specification:Resistance25:1.0~500K Ohm----normal 2.2K,5k,10k,10k,15k,20k ohmPrecision:0.5%,1%,2%,3%,5%,10%B25/50 Value3270,3380,3470,3550,3700,3950,3990,4200 etcShell TypeInjection Molding------IP68 grade of waterproof Expoxy-----mainly used for indoor Metal(stainless steel,Ni-Cu,Cooper)-----fast response, there are different shapes:  bullet type, cylinder type, surface mounting type, screw type, Megestism type, clamp type.
