HOW DOES IT WORK?
Thermo 28 Click is based on the AS6221, a digital temperature sensor from ams AG with increased reliability and improved accuracy specifications optimal for thermal management and protection applications. It integrates a digital temperature sensor with a SI bipolar transistor as a sensing element, 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 ±0.9°C typical over a temperature range of 20°C to 42°C.
This Click board™ communicates with MCU using the standard I2C 2-Wire interface to read data and configure settings, supporting a high clock frequency operation. It also allows the choice of the four least significant bits of its I2C slave address by positioning the SMD jumper labeled ADDR SEL to an appropriate position providing the user with a selection of four slave addresses. In addition to communication signals, the AS6221 also possesses an additional interrupt alert signal, routed on the INT pin of the mikroBUS™ socket, indicating when a specific interrupt event occurs that depends on the value of the temperature reading relative to programmable limits.
This Click board™ can only be operated from a 3.3V logic voltage level. Therefore, 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.
