How Does the Pressure 14 Click Board™ Work?
The Pressure 14 Click Board™ is based on the ABP2LANT060PG2A3XX, a piezoresistive silicon pressure sensor offering a digital output for reading pressure over the specified full-scale pressure span from Honeywell Sensing and Productivity Solutions. Its characterized by long-term stability and accuracy, ultra-low power consumption, a wide pressure range from 0 to 60 psi, and its compatibility with plenty of liquid media. Also, it is a perfect choice for pressure measurements in automotive applications, industrial and consumer applications.
The ABP2LANT060PG2A3XX defines an I2C configurable ABP2 Series Amplified Basic pressure sensor calibrated and temperature compensated for sensor offset, sensitivity, temperature effects, and accuracy errors. ABP2 series represents flexible and versatile sensors at which the calibrated output values for pressure and temperature update at approximately 200 Hz. The liquid media option includes an additional silicone-based gel coating to protect the electronics under pressure port, enabling usage with non-corrosive liquids (e.g., water and saline) and in applications where condensation can occur.
The Pressure 14 Click Board™ communicates with MCU using the standard I2C 2-Wire interface and supports both Standard and Fast Mode with a transfer rate of 100 and 400kbit/s. Following the address and read bit from the MCU, the ABP2 Series digital pressure sensors can output up to 7 bytes of data, using a default I2C address of 40 (28h). Also, it uses an additional pin, the INT pin of the mikroBUS™ socket, used as an 'end-of-conversion' indicator. This pin sets HIGH when measurement and calculation have been completed, and then the data is ready to be clocked out.
The Pressure 14 Click Board™ is designed to be operated only with a 3.3V logic voltage level. A proper logic voltage level conversion should be performed before the Click board™ is used with MCUs with different logic levels. However, the Click board™ comes equipped with a library that contains functions and an example code that can be used, as a reference, for further development.
