Digital Barometric Air Pressure Sensor 0-40KPa

The Digital Barometric Air Pressure Sensor 0–40KPa is a precise and reliable sensor module created for measuring low-range air pressure and liquid water levels. Because it provides digital output, it ensures easy integration with microcontrollers, automation systems, and industrial instruments. As a result, it is widely used in water tanks, pipeline pressure monitoring, medical devices, and smart liquid-level projects.

Performance and Accuracy

This module uses a high-sensitivity pressure transducer to detect pressure changes between 0 and 40KPa. Moreover, it delivers highly stable readings with minimal drift, even during long-term operation. Additionally, the built-in amplifier circuit provides clean and accurate voltage or digital signals, making it ideal for microcontroller platforms such as Arduino, ESP32, Raspberry Pi, STM32, and PLC systems.

Furthermore, the sensor responds quickly to pressure changes, allowing real-time monitoring for automation applications. Its compact and lightweight design makes installation simple, even in small or enclosed environments. Because it is factory-calibrated, users can expect consistent performance without complicated setup.

Liquid and Air Pressure Applications

One of the most common uses of the Digital Barometric Air Pressure Sensor 0–40KPa is liquid-level monitoring. When connected to a water tank or reservoir, it converts pressure at the tank bottom into an accurate water-level reading. Therefore, it is an excellent choice for smart irrigation systems, water pump automation, livestock water tanks, and industrial fluid monitoring.

Similarly, it works well for barometric pressure detection, airflow measurement, vacuum systems, and environmental monitoring devices. In addition, hobbyists can use it in DIY weather stations, atmospheric science projects, or custom robotics builds.
