This circuit diagram is a circuit of a humidity detector. The sensor consists of two sets of thin wires, each of which is closely spaced, about 2 mm. When there is raindrop falling or the air humidity is very high, the two sets of wire wires constitute the wire path, and the 6V power supply voltage is applied to the base of the transistor BG1 through the resistor R1, so that BG1 is turned on, and the voltage drop on R2 makes the thyristor SCR1 is turned on, and the alarm sends an alarm signal. The alarm can only be stopped by opening the switch K. Transistor BG1 is 2N3706, which can be replaced by domestic model 3DK9B.
We engineer loudspeaker solutions that offer great durability, quality sound, and peak performance. When an electrical signal is applied to the voice coil it generates a magnetic field. The voice coil and magnets within the Speaker interact causing the coil and attached cone to move, generating sound. Our loudspeakers incorporate large magnets and particular voice coils to handle a broad range of frequencies and sounds. Additionally, our loudspeakers can be configured in multiple cone materials, sizes, shapes and gaskets to adapt to different operational environments. We have provided loudspeaker solutions for both indoor and outdoor applications. Our loudspeaker designs can be found in home theater systems and on the handlebars of some of the most exquisite motorcycles.
