The ds18b20 dig it al thermometer provides 9-bit to 12-bit celsius temperature measurement and has an alarm function with nonvolatile user programmable upper and lower trigger points. The ds18b20 communications over a 1-wire bus that by definit ion requires only one data line (and ground) for communication with a central microprocessor. It has an operating temperature range of - 55c to + 125c and is accurate to 0.5c over the range of - 10c to + 85c. In addition, the ds18b20 can derivive 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 mult iple ds18b20s to funct ion on the same 1-wire bus. Then, it is simple to use one microprocessor to control many ds18b20s distributed over a large area.
Features
Unique 1-wire interface requests only one port pin for communication
Each device has a unique 64-bit serial code stored in an on-board rom
- multidrop capability simplifies distributed temperature-sensing applications
- requires no external components can be powered from data line; power supply range is 3.0v to 5.5v
- measures temperatures from - 55c to + 125c (- 67f to + 257f) 0.5c accuracy from - 10c to + 85c.
- thermometer resolution is user selectable
- converts temperature to 12-bit digital word in 750ms (max) - user-definable nonvolatile (nv) alarm settings
- search command identifies and addresses devices whose temperature is outside programmed limits
- available in 8-pin so (150 miles), 8-pin sop, and 3-pin to-92 packs
- software compatible with the dsapplications include thermostatic controls, industrial systems, consumer products, thermometers, or any thermally sensitive s
