YINGHUA International Power Cord 3.3V 40KPa
Digital barometric pressure sensor module measures 0-40 kPa for liquid level control at 3.3 V
- Measures pressure up to 40 kPa for liquid level control
- Operates from a 3.3 V supply for low-voltage systems
- Digital output simplifies microcontroller integration
- Supports 3.3 V to 5 V range for flexible power options
3.3–5 V Pressure Sensor Module
This digital barometric pressure sensor module operates from a 3.3 V to 5 V supply and measures up to 40 kPa. It is designed for builders who need a compact board to monitor liquid water level or atmospheric pressure in a custom project.
Integration Notes
The board connects to a microcontroller via a standard digital interface and requires a regulated 3.3 V or 5 V rail. It frees the host from implementing an analogue front-end, but buyers who need a wider pressure range or an analogue output will have to look elsewhere.

Questions about this item
What is the maximum pressure the 40KPa sensor can measure before it saturates?
The module reads up to 40 kilopascals; beyond that point the output stops increasing and the reading remains at full scale.
How much current does the board draw when it runs continuously from a 3.3V supply?
The sensor operates from 3.3V and draws only a few microamps in active mode, so heat and power stay negligible during all-day use.
