HOW DOES IT WORK?
Barometer 9 Click is based on the ENS220, a state-of-the-art barometric pressure and temperature sensor from ScioSense for applications such as activity tracking and indoor navigation/localization. This sensor stands out for its ultra-low power consumption and high accuracy, offering a dual-mode communication interface that can operate through digital I2C or SPI interfaces. Embedded within a CMOS ASIC, the ENS220's capacitive pressure sensor facilitates a compact package size while ensuring robust resistance to environmental changes. The integration of a capacitive read-out mechanism contributes to its minimal power usage. It boasts a high sensitivity to pressure and incorporates an ultra-low noise 24-bit ADC converter, minimizing pressure noise significantly. The sensor also includes a precision temperature sensor, providing stable, temperature-compensated pressure readings with quick response times.
Key features of the ENS220 include a pressure range from 300 to 1200hPa, exceptional absolute accuracy within ±0.5hPa, and relative accuracy of ±0.025hPa, which translates to an altitude resolution of around 20cm. Its ultra-low pressure noise of 0.1Pa RMS at a 2Hz sampling rate and the ability to adjust the sampling rate up to 1kHz, achieving 0.9 Pa RMS, is also noteworthy. Additionally, it delivers temperature measurements with an accuracy of ±0.1K and a resolution of 8mK.
Barometer 9 Click offers flexibility through its support for both SPI and I2C interfaces, selectable via the COMM SEL jumpers. By default, the I2C interface is active, supporting Fast mode operation up to 400kHz, whereas the SPI mode accommodates clock frequencies up to 1MHz. The sensor's interrupt feature is a significant addition, enabling it to alert the host processor about specific events, such as pressure thresholds, through the INT pin, optimizing for ultra-low power consumption scenarios.
The ENS220 operates optimally at 1.8V, a power supply level provided by the TLV700, a low-dropout (LDO) regulator from Texas Instruments, sourced directly from the selected mikroBUS™ socket's power rail. Because the ENS220's power supply is 1.8V, this board also facilitates appropriate logic level conversion via the TXS0108E voltage level translator from Texas Instruments.
This Click board™ can operate with either 3.3V or 5V logic voltage levels selected via the VCC SEL jumper. This way, both 3.3V and 5V capable MCUs can use the communication lines properly. Also, 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.
