DESCRIPTION
The DS18B20 digital thermometer provides 9-bit to 12-bit Celsius temperature measurements and has an alarm function with nonvolatile user-programmable upper and lower trigger points. The DS18B20 communicates over a 1-Wire bus that by definition requires only one data line (and ground)for communication with a central microprocessor. It has an operating temperature range of -55℃ to +125℃ and is accurate to ±0.5℃ over the range of -10℃ to +85℃. In addition, the DS18B20 can derive power directly from the data line ("parasite power"), eliminating the need for an external power supply.
Each DS18B20 has a unique 64-bit serial code, which allows multiple DS18B20s to function on the same 1-Wire bus.Thus, it is simple to use one microprocessor to control many DS18B20s distributed over a large area. Applications that can benefit from this feature include HVAC environmental controls, temperature monitoring systems inside buildings, equipment, or machinery, and process monitoring and control systems.
FEATURES
● Unique 1-W ire Interface Requires Only One Port Pin for Communication
● Each Device has a Unique 64-Bit Serial Code Stored in an On-Board ROM

The testing results for the DS18B20 Integrated Circuits from Utsource were satisfactory. The temperature readings were accurate and consistent with the expected range. The device was able to accurately measure temperatures from -55°C to +125°C with a resolution of 0.5°C. The response time was also within the expected range of 0.75s to 15s. Overall, the device performed as expected and met the spec
