Product Specification

Digital Output Pressure Sensor Cps121Compact Appearance, 3 X 5 X 1.2mm (Width X Length X Height)

• Calibration: Traditional solutions may rely on external calibration coefficients and require the host microcontroller to perform compensation calculations. In contrast, the CPS121 has internal calibration logic and is factory-calibrated, directly providing accurate pressure and temperature measurements without the need for external complex operations, making it more convenient to use.

• Output Format: Many conventional pressure sensors may output analog signals, which require subsequent analog-to-digital conversion. The CPS121 has a digital output, and pressure and temperature data can be obtained via the I²C interface, facilitating system integration.

• Power Consumption: Some regular pressure measurement devices have relatively high power consumption and are not suitable for battery-powered applications. The CPS121 has an average current consumption of less than 5 µA per measurement and a sleep state current consumption of less than 200 nA at 25°C, making it suitable for battery-powered scenarios due to its low power consumption.

• Clock Requirement: Some sensors need an external clock signal to ensure operation, which increases the complexity of system design. The CPS121 does not require an external clock, simplifying the system design.

Differential Advantages in Different Application Areas

• Smartphone Applications: Compared with ordinary environmental sensors with basic functions, the CPS121 can enhance the overall environmental sensing capabilities of smartphones with its high-precision pressure measurement ability. For example, it can more accurately determine altitude information and improve related functional experiences.

• Wearable Devices: In contrast to the relatively simple sensors in ordinary health and fitness tracking devices, the CPS121 has obvious advantages in high precision, low power consumption, and a compact size (3 x 5 x 1.2 mm). It can provide more accurate data support for health and fitness data monitoring (such as assisting in determining exercise status through pressure changes) without occupying much space and with low power consumption.

• Altimeter Applications: Compared with similar products with slightly lower precision, the CPS121 has a pressure absolute accuracy of ±0.1 kPa (±1.0 mbar) in the range of 0°C to 50°C and 95 kPa to 105 kPa, and a relative accuracy of ±0.01 kPa (<1 meter), which can provide extremely accurate altitude measurement values to meet high-precision measurement requirements.

• Weather Station Applications: Compared with some conventional barometric measurement devices, the CPS121's high-precision pressure and temperature measurement (temperature accuracy ±1.0°C) and stable and reliable performance make it a useful tool for meteorological data collection and can more accurately provide basic data for meteorological analysis.

• Industrial Equipment and Air Control Systems: Compared with traditional pressure monitoring and control components, the CPS121 has high media resistance and can adapt to various sensing media. It can stably and accurately perform pressure monitoring and feedback under different working conditions such as complex industrial environments, air flow and pressure management systems, ensuring the normal operation of the systems.
