Water Softener Salt Degree Monitor – Open Electronics

By on August 29, 2022

Water softeners work utilizing a course of known as ion alternate by which calcium and magnesium ions from arduous water are exchanged with sodium chloride (salt) through a particular resin. The water goes right into a strain vessel the place it strikes via the resin beads, and the calcium and magnesium are changed by sodium. The resin beads will ultimately develop into exhausted and unable to select up any extra arduous minerals. The recharge or regeneration course of passes a salt water answer via the resin beads which detaches the hardness minerals and flushes them harmlessly to the drain. The resin beads are left refreshed and able to make extra softened water.

Ion alternate water softeners are available in many styles and sizes however all of them have one factor in frequent, a brine tank that wants filling with salt each few weeks to ensure a daily provide of sentimental water. Water softeners usually are not precisely engaging items of kit and so they’re banished to some inaccessible place that means a particular go to is required to verify the salt stage. As a rule, the cue for including extra salt comes from family members griping about arduous water.


A match and neglect salt stage sensor is required that may ship a reminder when the salt is low within the softener. On this Instructable, a variety sensor is used to measure the salt stage within the water softener each few hours and the outcome posted on ThingSpeak. When the salt stage will get low, ThingSpeak will ship a reminder electronic mail to replenish the brine tank with salt.
All of the elements for this venture can be found on eBay, as common, the most cost effective elements come from Asia. Even having to purchase all of the elements, the full value will likely be about US$10. A mess of expertise like soldering or utilizing the Arduino IDE are wanted to make this venture. All these strategies are lined in different Instructables and usually are not repeated right here.
