HX710B Digital Barometric Pressure Sensor Module 0-40KPa Water Level & Liquid Flow Controller for Arduino

Description

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. This module is especially useful for measuring the water level in tanks, hydroponic systems, and reservoirs by converting water pressure into liquid height. Since you are building automated watering and in
