Build a Circuit indication for RF Output Transmitters On Air

This is an On Air indicator, ie an indicator schema dr RF transmission, very simple and useful for those who like RF. This schema detects the RF output using a visual indicator, but with some modifications, the LED may be replaced by a relay or any other system that want to trigger when the transmitter is switched on. The output of the transmitter or other RF generator must be connected to this RF input schema.

Simple Circuit indication for RF Output Transmitters

List of components

Resistor R1 560Ω eighth
Capacitor C1 330pF disc
C2 Capacitor 0.1μF disc
Diode D1 1N34 or 1N60
D2 LED
Transistor Q1 2N3904 or equivalent

Air Flow Detector

Here we have used an incandescent lamp as L1.When the bulb is getting heat the resistance will be increased.As air flows over the filament it cools down, thus lowering its resistance.If you want to see the amount of air flow.You can use a meter for that..And I hope to give you HHO Technology so at that situation this schema will be so usefull Still We do some test on it.

Parts:

C1 47uF Electrolytic Capacitor
R1 100 Ohm 1/4W Resistor
R2 470 Ohm 1/4W Resistor
R3 10k 1/4W Resistor
R4 100K 1/4W Resistor
R5 1K 1/4W Resistor
U1 78L05 Voltage Regulator
U2 LM339 Op Amp
L1 #47 Incandescent lamp with glass removed
D1 LED

Note

# You have to brake the lamp with out removing the filament.
