Brief description
18 | 19 |Four main metrics are measured and periodically reported over MQTT and a 3.5" Nextion touch screen: water temperature and pressure, pH and ORP values.
20 | Pumps states, tank-levels estimates and other parameters are also periodically reported
21 | Two PID regulation loops are running in parallel: one for PH, one for ORP
22 | An additional simple (on/off) regulation loop is handling the water temperature (it starts/stops the house-heating system circulator which brings heat to a heat exchanger mounted on the pool water pipes)
23 | pH is regulated by injecting Acid from a tank into the pool water (a relay starts/stops the Acid peristaltic pump)
24 | ORP is regulated by injecting Chlorine from a tank into the pool water (a relay starts/stops the Chlorine peristaltic pump)
25 | Defined time-slots and water temperature are used to start/stop the filtration pump for a daily given amount of time (a relay starts/stops the filtration pump)
26 | Tank-levels are estimated based on the running-time and flow-rate of each pump.
27 | Ethernet connectivity parameters can be set through a webpage accessible from the LAN at http://PoolMaster.local.
28 | If an ethernet connection is available, the internal clock (RTC) is synchronized with a time-server every day at midnight.
29 |
30 | An API function enables telling the system what the outside air temperature is. In case it is below -2.0°C, filtration is started until it rises back above +2.0°C
31 | Communication with the system is performed using the MQTT protocol over an Ethernet connection to the local network/MQTT broker.
32 |
33 | Every 30 seconds (by default), the system will publish on the "PoolTopicMeas1" and "PoolTopicMeas2"(see in code below) the following payloads in Json format:
34 | {"Tmp":818,"pH":321,"PSI":56,"Orp":583,"FilUpT":8995,"PhUpT":0,"ChlUpT":0}
35 | {"AcidF":100,"ChlF":100,"IO":11,"IO2":0}
36 | Tmp: measured Water temperature value in °C x100 (8.18°C in the above example payload)
37 | pH: measured pH value x100 (3.21 in the above example payload)
38 | Orp: measured Orp (aka Redox) value in mV (583mV in the above example payload)

42 | ChlUpT: current running time of Chl pump in seconds (reset every 24h. 0secs in the above example payload)

How to compile
69 |
70 | - this code was developped for two main hardware configurations (see list in the hardware section below):
71 |
-
72 |
- Controllino-Maxi or 73 |
- Arduino Mega 2560 + Ethernet shield + relay shield + RTC module
75 | 76 | 77 |
Compatibility
78 | 79 |For this sketch to work on your setup you must change the following in the code (in the "Config.h" file):
80 | - possibly the pinout definitions depending on your wiring
81 | - the unique address of the DS18b20 water temperature sensor
82 | - MAC and IP address of the Ethernet shield
83 | - MQTT broker IP address and login credentials
84 | - possibly the topic names on the MQTT broker to subscribe and publish to
85 | - the Kp,Ki,Kd parameters for both PID loops in case your peristaltic pumps have a different throughput than 1.5Liters/hour for the pH pump and 3.0Liters/hour for the Chlorine pump. Also the default Kp values were adjusted for a 50m3 pool volume. You might have to adjust the Kp values in case of a different pool volume and/or peristaltic pumps throughput (start by adjusting it proportionally). In any case these parameters are likely to require adjustments for every pool
Tips
88 | Before attempting to regulate your pool water with this automated system, it is essential that you start with:89 | 1- testing your water quality (using liquid kits and/or test strips for instance) and balancing it properly (pH, Chlorine, Alkalinity, Hardness). Proper water balancing will greatly ease the pH stability and regulation
90 | 2- calibrating the pH probe using calibrated buffer solutions (pay attention to the water temperature which plays a big role in pH readings)
91 | 3- adjusting pH to 7.4
92 | 4- once above steps 1 to 3 are ok, you can start regulating ORP
93 | 94 | Notes:
95 | a/ the ORP sensor should theoretically not be calibrated nore temperature compensated (by nature its 0mV pivot point cannot shift)
96 | b/ the ORP reading is strongly affected by the pH value and the water temperature. Make sure pH is adjusted at 7.4
97 | c/ prefer platinium ORP probes for setpoints >500mV (ie. Pools and spas)
98 | e/ the response time of ORP sensors can be fast in reference buffer solutions (10 secs) and yet very slow in pool water (minutes or more) as it depends on the water composition
99 | 100 |
Details on the PID regulation
101 |
102 | In this project the Arduino PID library is used to start/stop the chemicals pumps in a cyclic manner, similar to a "PWM" signal.
103 | The period of the cycle is defined by the WINDOW SIZE parameter which is fixed (in Milliseconds). What the PID library does is vary the duty cycle of the cycle.
104 |
105 | If the computed error in the PID loop is null or negative, the duty cycle is set to zero (the ouput of the function PID.Compute()) and the pump is never actuated.
106 | If the error is positive, the duty cycle is set to a value between 0 and a max value (equal to the WINDOW SIZE, ie. the pump is running full time).
107 |
108 | So in practice the ouput of the PID.Compute() function is a duration in milliseconds during which the pump will be activated for every cycle.
109 | If for instance, the WINDOW SIZE is set to 3600000ms (ie. one hour) and the output of the PID is 600000ms (ie. 10mins), the pump will be activated for 10mins at the begining of every hour cycle.
110 |
111 | On the default Kp,Ki,Kd parameter values of the PID:
112 | By default in this project, Ki and Kd are null for stability reasons and so the PID loop is only a P loop, ie. a proportional loop.
113 | Adding some Ki and Kd to the PID loop may theoretically increase regulation performance but is also more complex to adjust and could result in instabilities. Since a P-only loop worked well enough and that safety considerations should be taken seriously in this project, I left it as is.
114 |
115 | For my 50m3 pool the Kp default values are 2000000 for the pH loop and 4500 for the Orp loop. They were chosen experimentally in the following way:
116 |
117 | I experimentally checked how much chemical was required to change the measured parameter (pH or Orp) by a certain amount. For instance I determined that 83ml of acid changed the pH by 0.1 for my 50m3 pool. The flow rate of the acid pump being 1.5L/hour, we can then determine for how many minutes the pump should be activated if the pH error is 0.1, which are (0.083*60/1.5) = 3.3minutes or roughly 200000ms.
118 | And so for an error of 1 in the pH PID loop, the pump needs to be activated 10 times longer, ie. during 2000000ms, which should be taken as the Kp value. The same reasoning goes for the Kp value of the Orp PID loop.
119 |
120 | On the WINDOW SIZE:
121 | Various parameters influence the speed at which an injected chemical in the pool water will result in a variation in the measured pH or Orp.
122 | Experimentally I measured that in my case it can take up to 30minutes and therefore the injection cycle period should be at least 30mins or longer in order not to inject more chemical over the following cycles thinking that it required more when in fact the chemical reactions simply needed more time to take effect, which would eventually result in overshooting.
123 | So in my case I setlled for a safe one hour WINDOW SIZE (ie. 3600000ms)
