0.1Hz-30000Hz Schumann Resonance Pulse Sine Wave Generator Audio Frequency Saved When Power OFF Edition 0629

Usage Tips:1. Using materials, the frequency stability of products is good;2. This product can not only output 7.83Hz Schumann wave, but also add programmable frequency modulation technology, which can adjust the frequency in the range of 0.1Hz-30KHz;3. The frequency reference of digital circuit crystal oscillator is more stable and anti-jamming;4. The power supply interface adopts DC5.5*2.1 or Micro-USB interface, which is convenient to use. The USB terminal can work when plugged into a charging treasure or USB charging head or other USB power supply equipment.Product description:Shumanbo itself does not directly act on sound or video products to improve the sound quality, but on the spatial environment, so that people's body and mind can be relaxed, the body's perception of sound and images can be improved, the healthy work efficiency of the human body can be improved, and psychological pressure can be relieved. This product can not only output 7.83Hz Schumann wave, but also adjust the frequency in the range of 0.1 Hz - 30 kHz. The frequency reference of digital circuit crystal oscillator is more stable and more anti-jamming.Product parameters:Green compact :Antenna waveform: sine waveInterface waveform: sine wavePower supply interface: Micro-USBPower supply voltage: 5VRated power consumption: Less than 1WDefault frequency: 7.83HzAdjustment range: 0.1Hz-30000HzVoltage amplitude of sine signal: 3VVoltage amplitude of square wave signal: 5VChange the frequency method:Enter the frequency directly and press the lower left key to complete the setting.For example, press [7][.][8][3] and then press [OK] to set the default power-on output to 7.83Hz, and the setting range is 0.1-30KHz.Note:Due to different printing batches, if there are slight differences in the words in kind, it will not affect the use.Color:GreenMaterial:PCB+Plastic+MetalPackage Contents:1 * signal generatorOnly the above package content, other products are not included.Note: Lig
