Water Flow Valve Timer Controller Circuit
The article details about an automatic water flow controller timer circuit which switches a valve mechanism ON/OFF as per a set predetermined timing sequence. The idea was requested by Mr. John Clarke. Technical Specifications I’ve seen your site and designs and wondered if you could help with a controller I’m trying to design to control […]
Light Activated Water Level Controller Circuit
The light activated water level controller circuit explained here has the advantage of being corrosion free and much reliable than the traditional moisture sensor type of water sensors. Circuit Operation One slight downside of this LDR based sensor is that the tank interior always needs to be illuminated by some kind of light source such […]
Analogue Water Flow Sensor/Meter Circuit – Check Water Flow Rate
In this post I have explained a simple water flow meter/sensor circuit using hall effect sensor and a pulse counter circuit. Referring to the diagram shown below, we can see an arrangement consisting of a circular enclosure having a couple of pipes drilled in and a circular turbine shaped wheel installed inside the enclosure. How […]
Water Softener Circuit Explored
In this post I have explained a circuit design which can be used for softening hard water and for descaling it into soft water. The idea was requested by Dimple rathode. Technical Specifications My name is Dimple and i am an electronic hobbyist. I look up to your blog whenever i have any doubt regarding […]
How to Measure Dissolved Oxygen in Liquids
In this post I have explained a sensor device used for measuring the level or amount of dissolved oxygen in water and other fluids. The idea was requested by Mr. Amit Technical Specifications I didn’t find sensors or sensor modules for Dissolved Oxygen or pH readings for us to use with controllers for our projects. […]
