Product Description:
Radio transceiver principle is: reporting, the transmitter is required to send out information, and sends out the current of different frequencies and wavelengths, so that the electrons of the transmitting antenna constantly change the direction of rotation according to the frequency.
The tail of the magnetic force line is broken out and popped out, and the two ends of its moving magnetic line continuously attract space free space and Dan quality.
Particles grow themselves and form flat wave waves with different frequencies and wavelengths in all directions of space.
This "wave" touches the radio receiving antenna and drives its surface free electrons to revolve around the antenna at the frequency and wavelength of the "wave" to form an alternating current. This weak current is amplified and becomes the receiving information of the receiver.
The introduction of this small transmitter is a good technology small production, the principle is very simple.
The 2 X dry batteries are connected with a key switch, a resistor and LED lamp. Press the button, the circuit is switched on, and there is current passing through the LED lamp, and the light is generated. When the key is released, the current is gone and the report byte is completed.
We know that telegram sends messages through the length of sound (or signal). And our small transmitter, according to the control switch time length to control the sound interval, can distinguish between long sounds or short sounds to achieve the purpose of sending information.
Specifications:

Experimental steps:the experiment is ready to know the experimental equipment: screw holes, switches, resistors, wires, LED lamps, battery boxes, sounder, screwdriver, diagonal pliers.
Experimental report:
The principle of radio technology is that the change of electric current in a conductor will produce radio waves.
With this phenomenon, information can be loaded onto radio waves by modulation.
When the radio waves propagate through the space to the receiving end, the electromagnetic field caused by the radio waves will generate electric current in the conductor.
The purpose of information transmission is achieved by demodulating information from current changes.
