DS1920-F5 Economic Temperature iButton (-55°C to +100°C)




Minimum Order: 3 units

The DS1920-F5 is not a standalone Data Logger and cannot store the readings. It acts like a normal temperature sensor that has to be permanently connected to a computer. One or more units can be connected in series.
The DS1920 Temperature iButton provides 9-bit temperature readings, indicating the temperature of the device. Information is sent to / from the DS1920 through a 1-Wire Cable interface. Power to the DS1920 for reading, writing, and temperature conversions is sourced from the 1-Wire data line itself.

DS1920-F5 iButton Economic Thermometer

The DS1920 Temperature iButton provides 9-bit temperature readings, which indicate the temperature of the device. Information is sent to/from the DS1920 over a 1-Wire interface.
Power for reading, writing, and performing temperature conversions is derived from the data line itself.
Because each DS1920 contains a unique silicon serial number, multiple DS1920s can exist on the same 1-Wire bus.
This allows for placing temperature sensors in many different places.
Applications where this feature is useful include HVAC environmental controls, sensing temperatures inside buildings, equipment or machinery, and in process monitoring and control.
