Thermo 3 Click carries TMP102, a digital temperature sensor IC with a tiny footprint of only 1.6mm x 1.6mm. The Click is designed to run on a 3.3V power supply only. It communicates with the target MCU through mikroBUS™ I2C pins (SCL, SDA), and an additional Alert pint (INT on the default mikroBUS™ configuration).
TMP102 digital temperature sensor
Without requiring calibration, TMP102 is accurate within 0.5°C. Measurement range is between -25°C to 85°C. An integrated 12-bit ADC allows for measurement resolutions down to 0.0625°C.
You can set up an overtemperature alert using the ALERT pin (which sends an interrupt to the target board MCU). The sensor creates a highly linear output and therefore simple to use.
The ADD SEL jumper
Thermo 3 Click has an ADD onboard jumper (zero ohm resistor) for specifying the I2C address.
