Maxim/Dallas DS18b20 1-Wire Temperature Sensor IC provides 9-bit to 12-bit Celsius temperature measurements and has an alarm function with nonvolatile user-programmable upper and lower trigger points.

The Maxim/Dallas DS18b20 1-Wire Temperature Sensor IC communicates over a 1-Wire bus that by definition requires only one data line for communication with a central microprocessor. In addition, the DS18B20 can derive power directly from the data line, eliminating the need for an external power supply.

Each Maxim/Dallas DS18b20 1-Wire Temperature Sensor IC 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.

Maxim/Dallas DS18b20 1-Wire Temperature Sensor IC is a programmable resolution 1-wire digital thermometer in 3 pin TO-92 package. This digital thermometer provides 9bit to 12bit Celsius temperature measurements and has an alarm function with non-volatile user programmable upper and lower trigger points.

In addition, the device can derive power directly from data line by eliminating need for an external power supply. Each DS18B20 has a unique 64bit serial code stored in onboard ROM which allows multiple DS18B20 devices to function on the same 1-wire bus.

Thus, it is simple to use one microprocessor to control many Maxim/Dallas DS18b20 1-Wire Temperature Sensor IC devices distributed over a large area. Applications that can benefit from this feature include HVAC environmental controls, temperature monitoring systems inside buildings, equipment or machinery, process monitoring and control systems.

The Maxim/Dallas DS18b20 1-Wire Temperature Sensor IC measures temperature in degrees Celsius with 9 to 12-bit precision, -55C to 125C (+/-0.5C).
