The HX710B Digital Barometric Pressure Sensor Module is a high-precision pressure measurement board designed for detecting air pressure, water level, and liquid flow in Arduino, ESP32, STM32, and Raspberry Pi projects. The module combines a 0–40KPa pressure sensor with the HX710B 24-bit analog-to-digital converter, providing accurate and stable digital readings through a simple serial interface. It can be connected to a 2.5mm silicone tube to measure the pressure generated by water or air.
