HOW DOES IT WORK?
Barometer 12 Click is based on the ICP-10125, a high-accuracy, low-power, 10-atm waterproof barometric pressure and temperature sensor from TDK InvenSense. It is a very accurate sensor and can measure pressure differences with an accuracy of ±1 Pa, enabling altitude measurement differentials as small as 8.5 cm, less than the height of a single stair step. In addition to high accuracy, this sensor consumes only 1.3μA at 1Hz, making it ideal for battery-powered applications. According to the datasheet table, the sensor shows the best performance when operated with the recommended temperature and pressure range. The sensor works at 1.8V, which it gets from the AP2112, a CMOS LDO regulator from Diodes Incorporated.
Barometer 12 Click uses a standard 2-Wire I2C interface to communicate with the host MCU supporting clock frequency up to 400KHz. To allow safe sensor operation on both 5V and 3.3V voltage logic, this Click board™ features the PCA9306, a dual bidirectional I2C bus and SMBus voltage-level translator from Texas Instruments.
This Click board™ can operate with either 3.3V or 5V logic voltage levels selected via the VIO SEL jumper. This way, both 3.3V and 5V capable MCUs can use the communication lines properly. This 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.
