Monday Kids Mobile Phone Signal Flash Light DIY Kit 3-12V Radiation Power Electronic DIY Kit Fun

ICSK053A Precise DIY Kit Mobile Phone Signal Flash Light 3-12V Radiation Power

Phone call lights kit can be used to sense the GSM signal display, sensing distance up to 1 m, it is a very interesting DIY kit.

1. Electrical Characteristics

1). Supply voltage: 3 to 12V;
2). Sensing distance: about 1 m;
3). PCB board size: 2.2 cm * 2.8 cm;
4). Scope: GSM mobile phone signal, not available for CDMA mobile;

2. Circuit theory:

The main circuit is amplified antenna sensor signal circuit and circuit. Sensing signal through the antenna 3 to S8050 transistor amplifier to drive the LED, so that light up. When no signal is detected, no calls or no GSM phones, LED circuit is not only detects the signal to light up LED.

3. Assembly consideration:

Inductance of production:
Inductance 0.25 to 0.5 MM enameled available in pen core above can be around 5-10 laps. After a good round with a blade to scrape paint inductor 2, so we go soldered to the board.
