Digital Clock Activated Water Level Controller Circuit
An automatic clock time triggered water level controller circuit which responds to a real time clock input is discussed in the following article. The design also includes a water detection stage which makes sure the initialization takes place only in the presence of water in the tank or the pipe. The idea was requested by […]
How to Build an Ozone Water/Air Sterilizer Circuit – Disinfecting Water with Ozone Power
We are all familiar with thundering and lightning during stormy weathers and know how the effect is responsible of producing a lot of ozone and negative ions in the atmosphere. The same concept has been employed in the proposed water and air sterilizer circuit. Properties of Ozone Ozone is a pale blue gas having a […]
Remote Controlled Wireless Water Level Controller Circuit
For multi-storey buildings where water tanks could be at considerable heights over building terraces, monitoring the levels automatically could become a major issue. RF remote control modules have become pretty cheap nowadays which could be effectively used for solving the inconvenience. I have explained how to make and install a wireless water level controller circuit […]
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. […]
Refrigerator Motor Soft Start Circuit
Refrigerators tend to draw appreciable amounts of current each time their compressor switch ON, and this could happen many times per day. A soft start circuit to the compressor motor could probably tackle this issue and help save electricity. The idea was requested by Mr. Naeem Khan. Technical Specifications I need your help regarding to […]
