DS18S20 Temperature Transducer in Enclosure

We have mounted a DS18S20 on a PCB together with a RJ-12 socket which fits into a small plastic telephone socket enclosure. This allows you to easily mount the enclosure to a wall or other surface. A 6 wire telephone cable can be run from the KTA-001 to your controller or datalogger.

The DS18S20 digital thermometer provides 9-bit Celsius temperature measurements and has an alarm function with non-volatile user-programmable upper and lower trigger points. The DS18S20 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 °C and is accurate to ±0.5 °C over the range of -10 to 85 °C. In addition, the DS18S20 can derive power directly from the data line ("parasite power"), eliminating the need for an external power supply.

Each DS18S20 has a unique 64-bit serial code, which allows multiple DS18S20s to function on the same 1-Wire bus. Thus, it is simple to use one microprocessor to control many DS18S20s 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.
