Current-voltage conversion circuit is often used in the current detection circuit, shown 6-19 ring inverter air conditioner current detection circuit, the circuit is mainly use

d to detect the size of the supply current of the compressor motor. When the current is too large, you may damage the compressor motor, and even will burn the motor coil using current detection circuit for detecting the supply current, if found abnormal supply current, the air conditioner will automatically display the error code and immediate protection. When the AC 22V power supply for the compressor, the current transformer L2 induce a current signal, and then rectified by the VD2, Rl0 and Rll partial pressure and C13 cicada after wave input to the MB89865 feet. Current transformers and rectifier diode VD2 current consumption of the compressor will turn into a DC voltage supplied to the CPU (foot of snow, the A/D conversion and detection in the CPU, such as the voltage increases, will be protected. Diode VD] as a clamping diode, when the output voltage VD2 high voltage over 5v, VD1 DC voltage clamped at 5v.
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.....
