Water Level Controller Circuit A water-level-controller circuit monitors the level of the overhead tank and spontaneously switches on the water pump whenever the level goes below a specific limit. The level of the overhead tank is indicated using 5 LEDs, and the pump is switched off when the...
We need to have this circuit working all the time, even during power outages, so the power supply circuit must have emergency backup battery systems. The circuit below is a 12V/1A UPS circuit; it is the simplest one. If using a siren of less than 10W, a 1A power supply can be used....
There are many doubts and questions in the comments section. When you attempt this circuit, read through the comments carefully. Also keep in mind that there are many guys who got the output perfectly. This circuit is really good for beginners. 6.Water Level Alarm Circuit So here is another...
Battery Voltage Monitor Simple Electronics Projects Circuit Diagram When the voltage level of the battery falls to 10volts, the voltage at the inverting terminal is less than the voltage at the noninverting terminal. The OPAMP output goes high. LED2 begins to emit GREEN light which indicates that...
4Circuit Operation 4.1Using PWM as the Controller 4.2Circuit Diagram Basic Working principle The basic working principle of a buck-boost converter can be understood with the help of the following explanation. Referring to the basic buck-boost topology diagram above, when the switch S is closed, ...
When there is a power outage, the controller will drive the LEDs. This mini emergency light is special in that it does not use a relay to turn the LED on and off. But it uses the transistor to act as the switch instead. It begins with AC power being fed into the circuit. There is...
Circuit diagram of 12V to 24V DC DC converter. 12V to 24V dc dc converter circuit Notes. For L1, I made 60 turns of 22SWG enamelled copper wire on Type No CS166060 Sendust core. The approximate dimensions of the core are as follows. Outer diameter=0.6 inch, inner diameter= 0.3 inch ...
7-Segment Display Light controller Circuit Typical7 Segment displaycurrents should be restricted to approximately 25 mA, which is normally carried out through series resistors. When fitted with resistors, the display illumination cannot be any further altered. The circuit demonstrated here, alternatively,...
The controller provides protection functions such as automatic recovery after power failure and water leakage detection, improving the system reliability. The controller LCD displays the operating status and time of components in the smart cooling product in real time. ...
Coincidence or should I stop randomly changing controller settings to observe the effect? It took me a while of searching but I found the culprit… a tripped circuit breaker. My guess… we are running the reverse cycle heat on the 240V AC compressors and the startup of the compressor ...
