DS18S20Z+

The DS18S20Z+ is a 1-Wire parasite-power Digital Thermometer. 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. 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.

• Unique 1-Wire® interface requires only one port pin for communication
• Parasite power mode requires only 2 pins for operation (DQ and GND)
• Simplifies distributed temperature-sensing applications with multidrop capability
• Flexible user-definable non-volatile (NV) alarm settings with alarm search command identifies device
