fier circuit of the entire control circuit to provide the DC voltage corresponding to the flip-flop IC1 low water tower water pump control circuit, triggering circuit IC2 corresponding to the high-water wells to pump water for the control circuit.When the water level inside the water tower probe B, D tower above the water line, IC1 pin is ground level, so that IC1 be set, high pin output relay J1 pull, contact J1- 1 is closed, because the motor is energized and pumping operation performed pumping; when the water level rises to probe a, corresponding IC1 is reset, low output enable J1 release, contact J1-1 disconnect power pumps stopped, thus the water tower to achieve automatic control. Well placed in the probe B, D, under normal circumstances, should a certain depth below the water surface, so IC2 (555) by 2 feet high and reset, low output enable pin J2 pull, touch point J2-2 is closed. When leaving due to continuous pumping B, D EXPLORATION high in the water, IC2 occur due feet set low, high output enable pin J2 release, contact J2-2 disconnect the motor off electricity stopped, thus avoiding motor idling, while the water level of wells for testing.
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
