DS18B20 TO92 Sensor Digital Temperature

DS18B20 TO92 Sensor

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 -55ÁC to 125ÁC and is accurate to ±0.5ÁC over the range of -10ÁC to 85ÁC.

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.
