APPLICATIONS
• temp.control (heating, air conditioning, food and stock cooling)
• monitoring and alarming (server cabinets and rooms)
• temperature data logging (long time analysis)
• production quality control (industrial, medical, food processing)
SOFTWARE AVAILABLE
• Dallas DS 18B20 digital temperature sensor with 12 bit resoultion
• Wide range: –55 °C to +125° C / –67 °F to +257 °F
• Accuracy: ±0.5 °C (–10 °C to +85 °C) / ±0.9 °F (+14 °F to +185 °F)
• Dallas 1-wire interface
• Rubber encapsulated cable (33 cm /1 ft.) and housing with mounting hole
TECHNICAL SPECIFICATIONS
• Unique 1-Wire® interface requires only one port pin for communication
• Derives power from data line (“parasite power”) – does not need a local power supply
• Multi-drop capability simplifies distributed temperature sensing applications
• Requires no external components
• User – definable non-volatile temperature alarm settings
• Alarm search command identifies and addresses devices whose temperature is
outside of programmed limits (temperature alarm condition)
• Software compatible with the DS 1822-PAR
• ideal for use in remote sensing applications (e.g., temperature probes) that do not have a local power source
• Thermometer resolution is user-selectable from 9 to 12 bits
• Converts temperature in 750 ms (max.)
• Wide range: –55 °C to +125 °C / –67 °F to +257 °F
• Accuracy: ±0.5 °C (–10 °C to +85 °C) / ±0.9 °F (+14 °F to +185 °F)
