Pressure 20 Click Board™

Product Code: MIKROE-5153

How Does The Pressure 20 Click Board™ Work? The Pressure 20 Click Board™ as its foundation uses the ICP-20100, a high accuracy, low power, barometric pressure, and temperature sensor solution from TDK InvenSense. It integrates a capacitive pressure sensor for monitoring pressure changes in the range from 30kPa to 110kPa with an accuracy of ±20Pa over a wide operating temperature range. The ICP-20100 achieves the industry's lowest pressure noise of 0.4Pa RMS while attaining the industry's lowest power consumption and retains excellent temperature stability with a temperature coefficient of ±0.4Pa/°C. This MEMS sensor consists of a capacitive pressure sensor whose capacitance changes according to the pressure applied. An integrated temperature sensor on the same MEMS sensor allows accurate temperature measurements. Other industry-leading features include up to 20-bits output data, programmable digital filters, calibration, FIFO, and programmable interrupts. The Pressure 20 Click Board™ allows using both I2C and SPI interfaces with a maximum frequency of 1MHz for I2C and 12MHz for SPI communication.

The selection can be made by positioning SMD jumpers labelled as COMM SEL in an appropriate position. Note that all the jumpers' positions must be on the same side, or the Click board™ may become unresponsive. While the I2C interface is selected, the ICP-20100 allows choosing the least significant bit (LSB) of its I2C slave address using the SMD jumper labelled ADDR SEL. This Click board™ also possesses an additional interrupt pin, routed to the INT pin on the mikroBUS™ socket, indicating when a specific interrupt event occurs, such as FIFO overflow/underflow, the threshold over/underrun, and more. The Pressure 20 Click Board™ can be operated only with a 3.3V logic voltage level. 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.
