on I2C devices the power supply is not transferred to the data and clock lines as these are open drain so they only switch low and need to be pulled high via a pullup resistor, some modules have these on board so if you wish to use 5V they should be removed and replaced with resistors to the 3V3...

on the ads1115 there are 2k7 resistors on the board which pull the sda and scl lines high to Vcc, if you remove these you can run the device from 5V and pull the Comms lines high to 3V3 with 4k7 or 3k3 resistors separately instead. the 18B20 can be treated similarly by supplying with 5V and...

uploaded the new build everything working nicely on my esp32 C3 super mini board just need to check my pressure calibration with the ADS1115 and XGZP6847A looks to be working. excellent work thanks

I have the solution for the sleep issue I have just set the voltage above the config setting (just as with the gravitymon project). I have an issue with the pressure blanking out with a small positive value, does this need to be calibrated with full pressure before it will work? I can read small...

i have been testing this out on an esp32 C3 super mini board with the ADS1115 and a xgzp6847, i have it working but have a snag, it went to sleep and refuses to wake up, is there any way to disable the sleep function as i won't be needing it, i want the device to be always on. also the display...

i think that would work perfectly as the devices are internally calibrate with a dedicated chip and work between 0.5V and 4.5V with a linear profile, mine are 0 to 200kpa.

i used copper pipe to adapt from 3mm to 8mm (both sizes are used in refrigeration) to connect into the spunding valve pressure guage point soldering the two pipes sizes together, the ads1115 facility will be helpful to get this project working for me as i have plenty of them

have you considered the xgzp6847 pressure sensor? cheap small and can be contained on the PCB in the project box with just a 3mm pipe to connect to the fermenter/keg, uses the analog input to the ESP32 and runs from 0.5V to 4.5V on a 5V supply but can run on 3.3v. it's the device i am using at...

great i will definitely have a look at this, have been using pressure monitoring on an esp8266 for a long time now to keep an eye on my pressure ferment but it's quite a simple setup compared to yours

i haven't used the unit for any kind of control other than manual adjustment of element power. I find the neck temperature gives some indication of when i am at the ethanol product point and therefore at the hearts production, i understand that the still temperature should be able to give an...

update to the project, missed out the output to the two temperature sensors on the diagram. The tester is to determine the addresses of the two temperature sensors and assign them to the correct place within the code, rename to .ino and run in Arduino. DeviceAddress TopHeat =...

Hi I have been distilling for the last year and a half and put together this device to show the temperature of both the neck and keg of my still, also as I live at 1500 meters I have included a BME280 to calculate the boiling point of methanol, ethanol and water so I have an idea what the still...

thanks, i must have an issue with my network setup then.

if there are no endpoints defined will anything be shown?

Hi Mper I have constructed the gateway unit in the hope it will show me what the gravitymon C3 super mini devices are send out as i am having difficulty with the push targets. does this devices screen echo the data received over WiFi direct before pushing the data on? so far all i can see on the...

I have been using a rapt pill for over 1 year now, very helpful for tracking the ferment and catching problems especially with sugar washes, one critique is that it doesn't like going out of the area of the wifi and into a repeater out the same ssid. it works with my pressure fermenter very well...

check your door seal, it happened to me and that was the cause.

is it possible to use a PCF8574 for I/o to drive the relays?

did you ever manage to get this display working? I have one that I would like to use

I make black and tan regularly but sometimes when one or two ales don't turn out quite as desired blending can fix or improve
