THERMO 2 click carries DS1825, a programmable resolution digital thermometer IC with a unique 64-bit address. The click is designed to run on a 3.3V power supply. The board communicates with the target microcontroller through a 1-wire interface. Using the onboard jumper you can select between two outputs: GP1 (default mikroBUS™ AN pin), and GPO (default PWM pin).
The sensor aboard THERMO 2 click measures temperature within a range from –10°C to 85°C with ±0.5°C accuracy.
You can specify the resolution of the measurements, from 9 to 12-bit, depending on the application. Because each DS1825 has a unique 64-bit serial code, many of them can function on the same 1-wire bus.
The 4-bit location address lets you set up a unique ID for up to 16 sensors that operate on a single 1-Wire bus.
The board features a set of four onboard jumpers (zero ohm resistors) for specifying a unique address for the sensor.
A separate jumper lets you select the sensor’s output between GP1 and GP0 pins.
THERMO 2 click also features four Address Select jumpers for setting a unique ID for the sensor (allowing for up to 16 sensors to operate on a single 1-Wire bus).
