Arduino; Chlorination; Water treatment system; Intelligent systems; . The sensors are for environmental conditions like air temperature. it is only accurate at higher flows. Phase 2: water level adjustment to add or drain by itself. I found that I had to do my own 2 point calibration in order to get an accurate result. For example, if you are trying to kill wee beasties in your pool, you are interested in the HOCl (hypochlorous acid). Build KnowFlow: automatic water monitor. if you cannot get a chlorine sensor for air, you might as well let the output of the exhaust go through a water bubbler so the chlorine gas is solved/captured in the water. #0072c6 . Your best bet would probably be to interface with a colorimeter. Why you want to quantify the chlorine matters. If nothing happens, download GitHub Desktop and try again. Since a P-only loop worked well enough and that safety considerations should be taken seriously in this project, I left it as is. Other environmental conditions such as air temperature are measured and reported as well. Then would also have to control the pool filter when to turn on/off and maybe add remote options for controlling it and setting on timer. THOUSAND OAKS, Calif.

Pass the BNC of ORP's circuit board though the rightmost hole of the waterproof box, fix it to the mounting plate with screws, install EC and pH in the same way. Adding a chemical like chlorine helps keep the water clean. 18.28 kB - Since they describe this as being a Pool & Spa Redox sensor and described as long lasting, I strongly suspect that theres non-lab-grade sensors (which is what youre talking to) that last a bit under this use. Requirements: relatively inexpensive (under $100us), works with Arduino, waterproof and used to detect chlorine in water. 2.14 kB - With this two point you can write the exact equation for pH -sensor value . I gave you some links. It would need to be water proof. You might find that a simple conductance meter will work just fine? From phidget user forum site on adapting equation for Arduino connection: Does it means my formula will be 0.0178*(Vin*200)-1.889 as my input is (0V-5V)? The code used for both is almost the same, with only one factor to be modified. The fluid being measured must not contain any cleaning agents (e.g. Roel Van de Paar 106K subscribers Subscribe 6 416 views 1 year ago Arduino: A waterproof Chlorine Sensor Helpful? How you go about getting the water, and adding the reagent, well, that's certainly going to be half the fun. If you add too many chemicals at the wrong time you waste lots of money; add too few chemicals and your pool water quality won't be good enough to swim in. Agree Note! Can this data be translated to customer in a way they understand it i.e. The display will be for showing on the system packaging the current state of the pool water quality. Did some background development testing with Arduino and Wi-Fi (, Researched different types of sensors (air temp, water temp, light exposure, etc.) Control temperature for up to 8 separate processes! There are three "gates" in the front of the temperature signal adapter board. The you try to imagine what type of program you would write to read the sensors -- then to display the sensors. Connect S to digital pin number 8 on Arduino board. - (GND) pin: is a ground connection. Most important question to answer is can the probes be used to accurately predict overall water quality? That data is then uploaded to xively.com where the data is not just. Filtration pump will not run after that hour, {"PubPeriod":30} -> set the periodicity (in seconds) at which the system info (pumps states, tank levels states, measured values, etc) will be published to the MQTT broker, {"PumpsMaxUp":1800} -> set the Max Uptime (in secs) for the Ph and Chl pumps over a 24h period. My Jandy Chlorine generator sucks and spare parts are hideously expensive. For my 50m3 pool the Kp default values are 2000000 for the pH loop and 4500 for the Orp loop.
