HOW DOES IT WORK?
Thermo 27 Click is based on the TMP114, a digital output temperature sensor from Texas Instruments with increased reliability and improved accuracy specifications optimal for thermal management and protection applications. The TMP114 consists of an internal thermal BJT (factory calibrated on a NIST traceable setup), a high-resolution analog-to-digital converter (ADC), a data processing circuit, and serial interface logic functions in one package. The voltage is digitized and converted to a 16-bit temperature result in degrees Celsius, giving a fully calibrated digital output with outstanding accuracy of up to ±0.3°C and temperature resolution of 0.0078 °C, typical over a temperature range of -10°C to 85°C.
The TMP114 possesses two operational modes: Continuous-Conversion (CC) and Shutdown Mode, designed for thermal management and protection applications. In the CC mode, ADC performs continuous temperature conversions and stores each result in the temperature register, overwriting the result from the previous conversion, while the Shutdown mode reduces power consumption in the TMP114 when continuous temperature monitoring is not required.
This Click board™ communicates with an MCU using the standard I2C 2-Wire interface to read data and configure settings, supporting a high clock frequency operation. The TMP114 also includes an alert status register with individual high and low thresholds along with adjustable hysteresis values., which indicates via the I2C interface when a specific interrupt event occurs that depends on the value of the temperature reading relative to programmable limits.
This Click board™ can be operated only with a 3.3V logic voltage level, while the onboard LDO, the AP7331, ensures that the recommended voltage level powers the TMP114. The board must perform appropriate logic voltage level conversion before using MCUs with different logic levels. However, the Click board™ comes equipped with a library containing functions and an example code that can be used as a reference for further development.
