Hi everyone, I'm working on a project to replace a failing "smart habitat" for my dart frogs. I have connected 3 types of sensors, 2 of each type, and I can read and use the values and averages thereof. I can set and save values for timers I'm using to control the lights and sprinklers through a r…

Thanks @jremington for the decicion tree. I have added a timer in the conditions to prevent conditions to influence each other rapidly. I am still looking into hysteresis for the sensor readings. Not sure how to implement it yet, but for now I think a 10 seond delay will be alright (if I wrote it co…

[image] arneko: I am still looking into hysteresis for the sensor readings. Not sure how to implement it yet There is nothing much simpler than the hysteresis algorithm: if value exceeds upper limit { turn on } if value exceeds lower limit { turn off } else { do nothing }

[image] anon57585045: There is nothing much simpler than the hysteresis algorithm: The principle is simple, but I am unsure where or how to implement it. Or if I already have it and should leave it at that. I get data from sensor 1 and sensor 2 and combine them to make readingAverage. If ( …

[image] arneko: if (AirTempA > maxAirTemp && != hold) { This is incorrect in C. Does it even compile?

Indeed it does not. I was just sketching my ideas. I've now changed them to " hold == false "

If you make any changes, please repost the entire modified sketch. We can't offer concrete suggestions on "ideas", if we do, they are also just "ideas". It's a better policy to attempt to write actual code. If you are attempting to communicate the logic of the program, C code is a bad way to do it.…

alright, I'll try to keep ideas and code seperate and compile any code before I post them. Currently this is the state of the code: void climateControl() { static unsigned int maxAirTemp, minAirTemp; static unsigned int maxHumidity, minHumidity; //static unsigned int maxWaterTemp, minWaterT…

i find it difficult to understand for sure what the logic is i think the code could be simplified by broadly creating an if statement for when the temp > max threshold and under that condition consider other conditions such as the humidity, ... i think digitalWrite()s to motors and relays could a…

[image] gcjr: i find it difficult to understand for sure what the logic is And I thought I was too stupid to understand that too.

after trying to go thru the code, it seems it mostly boils down to the following. the PWM value is proportional to the air temperature within the limits. i don't understand your use of timers void climateControl () { unsigned long msec = millis(); tempAir = map (analogRead (A1), 0, …
