Are you using Resistors in your Circuit..
beautiful, thank you for giving reef-pi a shot :-0) . Welcome to reef2reef. Temperature sensors all share a common wire, GPIO 4. Irrespective of how many you use, it's called one wire bus.Hello everyone.. I wanted to start with saying amazing job on Reef-Pi. I dont have mine up and running the tank yet but it should be soon. I also have a few questions I'm going to have 3 temp probes do I just select any pin I'm not using for my other two probes or are there certain pins I need to use? Also hows the PH probe going? I have not seen anything on how to hook it up. Sorry when it comes to the programming side of things I'm not very savvy. So understanding how the tech end of things work I'm lost, and trying to learn as much as I can. Thank you.
Attached a pic of my Reef-pi in progress.
I am in process of finishing up the pH monitor build. It will be published next week hopefully, Its been for few months now, but I never got to document the build guide.
My Next project . will be one day when its to cold to work
No resistors on the pi hat the optical sensor has a 3 pin connection that goes to a break out board with 4 wires going to the sensor.Are you using Resistors in your Circuit..
Here is the example i used to wire mine. I think your missing the resisters unless they are on the back side of your hat .
In your dashboard configuration under ato you have nothing selected. this will cause this error.. removing the ato from the dashboard totally and check the ato sensor in the ato tab.
It will take a few min for it to start working..
Your circuit and configuration looks correct for photo electric sensor. Are you using float switch ?Here's the circuit.
The error message comes up every time the sensor tries to take a reading I have it set for every 10 seconds.
ATO page.
Thank you for the help on the temps and also on the ph I'll be keeping an eye out for it. I haven't ordered the PH probe yet but I want all my jack for everything installed before I mount the box. Thanks again.. and amazing job.
your circuit looks fine to me. If you probe the three pin (5v, GND and GPIO 17) on the male header jumper, do you get expected reading, particularly when you put the sensor in and out of water?No resistors on the pi hat the optical sensor has a 3 pin connection that goes to a break out board with 4 wires going to the sensor.
ugh. that s a bummer. Feels like a lot of wasted money now.
In your screen shot above the Dashboard Configuration under ato on the right you do not have a ATO Selected ..
@Erica-Renee is simply awesome :0)
