Thermo 25 Click, as its foundation, uses the TMP127-Q1, a factory-calibrated digital output temperature sensor designed for thermal management and thermal protection applications from Texas Instruments. This sensor is characterized by high accuracy; a temperature range of -55°C to +150°C provides typical ±0.8°C accuracy, also containing a 14-bit ADC to monitor and digitize the temperature reading to a resolution of 0.03125°C per LSB. The wide supply voltage range, low supply current, and SPI-compatible interface make it ideal for various applications, including process control, environmental monitoring, domestic appliances, and many more.
The TMP127-Q1 possesses two operational modes: Continuous-Conversion (CC) and Shutdown Mode. In the CC mode, ADC performs continuous temperature conversions and stores each result to the temperature register, overwriting the result from the previous conversion, while the Shutdown mode reduces power consumption in the TMP127-Q1 when continuous temperature monitoring is not required. The TMP127-Q1 always powers up in the Continuous-Conversion mode, while the Shutdown mode can optimize current consumption for low-power applications.
This Click board™ communicates with MCU through a standard SPI interface (compatible with SPI or MICROWIRE bus specifications) supporting the two most common SPI modes, SPI Mode 0 and 3, with a maximum frequency of 10MHz. The SPI interface features a simplified no register map protocol with a read-write 4-wire configuration. Writing to the TMP127-Q1 will allow the system to use the Shutdown mode and read the device ID.
This Click board™ can operate with both 3.3V and 5V logic voltage levels selected via the VCC SEL jumper. This way, it is allowed for both 3.3V and 5V capable MCUs to use the communication lines properly. However, the Click board™ comes equipped with a library containing easy-to-use functions and an example code that can be used, as a reference, for further development.
