## Overview

The DWEII Air Pressure Sensor Module Board is a compact, high-precision digital barometric sensor designed for Arduino and similar platforms. Operating within a 0-40KPa pressure range and 3.3-5V voltage, it supports liquid level and air pressure detection via 2.5mm soft tubing. Sold in packs of six, it offers excellent value for multi-sensor projects, featuring easy integration without I2C bus complications.

## Description

Introduction: Size: 19*18mm (2mm fixing hole) Voltage: 33-5V Pressure: 0-40KPa This module adopts high precision AD sampling chip and 0-40KPa air pressure sensor And it can connect 25mm soft tube and detect the water level and other air pressure Adopt 5K ohm resistor bridge sensor, and specific air pressure value needs calculating Package includes: 6x 33-5V Digital Barometric Pressure Sensor Module

Review: These work great on my old school Arduino but I did learn a few things about how to get set up with them. First, they are not I2C devices and don't put them on a I2C bus with other things. You can use regular IO pins and some simple code (that you can google) to get your readings. And as they are not actual I2C devices, you don't really need pull-up resistors on them, I got readings with regular PINMODE commands on D6 and D7. There is a mode to get temperature readings if you delve into the data sheet. Overall, these just work for me but I had to adjust my design to keep them off my I2C bus.
Review: I was able to connect with these easily using the HX711 platform within ESPHome. The measurement was good, however I soon found out the that sensor leaks air. I am measuring water tank level in a 50 gallon tank with a dip tube. Initially, the device correctly measures the head pressure when I submerge the tube, however the reading slowly decreases over time, and water slowly fills the tube. Just to confirm the theory, I submerged the pressure sensor in a glass of water and watched the bubbles slowly seep out from the bottom of the pressure sensor. You can see one such bubble in the attached image. I removed the pressure sensor from the board. It is marked Longway LWP040.

*by D***R on 24 November 2022*

I have tested 3/6 of them, and they don't work. I tested on pi, with working i2c bus (that has other things on it, that correctly show in i2cdetect.) maybe I am doing something wrong, but they really don't seem to be standard functional i2c devices.
