        <description>Water meter monitoring

Hardware

Using a ESP32 with QMC5883L compass module. TBD

Accuracy

Quite accurate, each interval (max to min to max) from the water meter appears to be 32.5ml, this was confirmed over the course of a few days and about 1.6 m³ of water (about 49 thousand intervals).</description>

Some Eee PC customizations via shell script

	*  Disable suspend to ram when AC adapter is plugged in and the lid is closed.

        <description>LCD Display

MJKDZ I2C board from eBay.

Notes:

	*  eBay search for board
	*    * I2C address is actually 0x20, not 0x27
	*  I&#039;m using the New LiquidCrystal library
	*  Need pull-up resistors on SDA and SCL lines (A4 &amp; A5 pins)

Test Code

#include &lt;Wire.h&gt; 
#include &lt;LiquidCrystal_I2C.h&gt;

#define lcdAddr 0x20 // set the address of the I2C device the LCD is connected to
// create an lcd instance with correct constructor for how the lcd is wired to the I2C chip

Still not working. Might be software or hardware, I&#039;ll need to check it on a digital oscilloscope.

        <description>Sump pump Monitor



My parents have a cistern and a sump pump which would be useful to have some sort of water level monitoring.

In the past, we would check the cistern level with a pressure gauge calibrated in inches of water. There was a rubber squeeze bulb which which would pressurize a plastic line which fed into the cistern, and the resulting level would be shown on the gauge.</description>
