SMECD04 Adjustable 7.83 Hz Schumann Resonance Signal Generator, 0.01 Hz–100 kHz with Overvoltage, Overcurrent and Surge Protection

Design thoughts: The old version is a popular and popular Schumann wave signal generator, but it also has many defects, such as: some frequencies cannot be set correctly, sometimes the LCD cannot start normally, the power supply is easy to burn out, etc. The upgraded version SMECD04 of eletechsup has improved these defects of the old version and retained its excellent functions. Their comparison is as follows:

Old version:
Normal key input
Many frequencies are missing
No power surge protection
No power overvoltage protection
No power overcurrent protection
No Parameters Power-off saving

Upgraded version:
Encoder input
Frequency is continuously adjustable
With power surge protection
With power overvoltage protection
With power overcurrent protection
With Parameters Power-off saving

Product Features:
1 Working voltage: DC 5V
2 Working current: 13-20MA
3 Power interface: DC5.5*2.1
4 Default frequency: 7.83Hz
5 Adjustment range: 0.01Hz~100000Hz (Continuously adjustable)
6 Waveform: Sine wave/Square Wave/Reverse Square Wave

9 Size: 150*140*26MM(Without shell) ,155*145*18MM(With shell)
10 Weight : 296g(With shell)

How to use:
1 Connect the board to a DC 5V power supply, and the LCD will display ''Sin(Hz):7.83''.
2 Then place it in a suitable position to experience the Schumann Resonances signal.


SMECD04 signal generator 0.01HZ-100000HZ adjustable, the steps are as follows:
0.01-99.99HZ: step 0.01HZ
100.0HZ-999.9HZ: step 0.1HZ
1000HZ-9999HZ: step 1HZ
10000HZ-99999HZ: step 10HZ
Frequency 0.01HZ-100Khz adjustable
