From 9 to 12-bit resolution measurements, Thermo 2 click board communicates with the target MCU through a 1-Wire interface.
We’re kicking off a series of new clicks with 1-Wire interface. Just to show how much you can do with only a single port pin available from the MCU.
Two things make the DS1825 IC that’s on Thermo 2 click especially suitable for applications where you need a multitude of sensors as part of a data logging network. First, each sensor has a unique 64-bit address. Second, you can setup a unique ID for each sensor using a 4-bit location address. That means you can connect up to 16 sensors to a single bus.
Thermo 2 click has four jumpers that for conveniently setting up that 4-bit address.
Another, equally convenient jumper, is for selecting one of two available mikroBUS™ pins for the sensor output.
As for the measuring range, Thermo 2 click handles between –10°C to 85°C, with a ±0.5°C accuracy. According to the data sheet, the sensor converts the temperature to a 12-bit word in no more than 750 milliseconds.
