This rain detector using two transistors, is a simple circuit that aims to alert the beginning of the rainfall. The applications for this circuit can be many, but the most obvious is to alert people who have their clothes drying under the sun or the wind, to put them under the roof before they get wet again.
Schematic diagram of the detector is presented in Fig. 2.42. Reference the generator of the metal detector is built on a capacitive treatacne on the transistor T1. Contour coil L1 is a sensor device. The capacitors C3-C6 are used to set the generator frequency to 50 kHz.
This is a ultrasonic motion detector (or movement detector) circuit. The circuit claimed has a high movement sensitivity. Even air moving (hot air rising, wind blowing) will trigger it when the trimpot is set near the most sensitive position. The transmitter sends out a steady ultrasonic tone at 40kHz. At this frequency the wavelength is ...

GigaHertz Signal Detector Circuit. This circuit is useful to detect microwave (gigahertz signal) sources like microwave oven, satellite communication devices, Mobile phones etc. It gives audio visual indications when it detects the Microwaves in the Gigahertz band. Microwave is the form of EM radiation with frequencies between 2 GHz and 300 GHz.
Mar 09, 2020 TWO-TRANSISTOR DC-AC CONVERTER SCHEMATIC CIRCUIT DIAGRAM. Assume that when the DC is applied to the given circuit, the T1 transistor is conducting with the current passing through the N2 and R1 resistors at the first moment. As the current from R1 flows from N1, it can not reach its maximum value immediately. (The maximum value is only after 5 t.)

AC motor windings. One of the characteristics of an alternating current motor (AC motor) is the number of rotor poles. This data will automatically give the number of windings that the motor has: # windings = # poles x 2. For example: If a motor has 4 poles, then the motor has 8 windings. If a motor has 6 poles, then the motor has 12 windings.
A simple metal detector transistors: (a) schematic diagram; b - design of the metal detector. The scheme collected on transistors operating in the mode of micro, and consists of an RF generator (100 kHz) on VT1, which is configured by the resistor R1 to the maximum sensitivity to metal objects. As the coils L1 and L2 are two frames (Fig. 2.50, b).
It is tapped at the first winding from the ground. L3 is made of 0.8mm copper wire, 8mm winding diameter, 3 windings at the FET side and 2 windings at the antenna side. Adjust the coupling between the two windings sides to get a maximum signal output amplitude. The circuit can be powered with a 9 volt battery. It consumes around 20mA only.
One kind of full-wave rectifier, called the center-tap design, uses a transformer with a center-tapped secondary winding and two diodes, as in the figure below. Full-wave rectifier, center-tapped design. Positive Half-Cycle. This circuit’s operation is easily understood one half-cycle at a time.
A circuit diagram or wiring diagram uses symbols to represent parts of a circuit. Electrical and electronic circuits can be complicated. Making a drawing of the connections to all the component parts in the circuit's load makes it easier to understand how circuit components are connected.
Two feedback windings (L1 and L2) using two turns each of 19 SWG wire are wound on the same core. These windings are connected to transistors T1 and T2 with a phase difference of 180o, as shown by the polarity dots in the figure. First wind the primary winding (90 …
Notes: This circuit is known as a latching circuit, because it “latches” in the “on” state after a momentary action. The contact in parallel with the “Run” switch is often referred to as a seal-in contact, because it “seals” the momentary condition of the Run switch closure after that switch is de-actuated.. The follow-up question of how we may make the motor stop running is a ...
