The Thermo 3 Click Board™ is based on the TMP102 digital temperature sensor from Texas Instruments, 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.
Alert pin
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.
Application
Because of its accuracy, the Thermo 3 Click Board™ is ideal for thermal-management and thermal protection applications, especially for extended measurements (in thermostats, office machines, industrial instrumentation applications).
