IL300 Optical Audio Signal Separator Low-Frequency
Linear optocoupler IL300 One of the diode is part of the output circuit, the other is used as feedback. IL300 optocoupler is suitable for both direct and transfer AC signal with a bandwidth of 200 kHz via a linearity of up to 0.01%. The function is stable in terms of temperature, while the temperature coefficient is only ± 0.05% / oC. The effective value of the insulation voltage, which lasts at IL300 trial period is 1s 5300V. Transmitter, the input side is emitting diode AlGaAs. Operating current can be between 0.5 mA to 40 mA, the best linearity is at 5 mA. On receiving feedback side of the silicon photodiode operating at a radiation source current. optical transmission occurs at a wavelength of 890nm.
MQ-4 ATmega48 Gasleckdetektor
Gas-Detektor-Schaltung ATMEGA48-mikrocontroller basierend auf dem verwendeten gas sensor-MQ-4 gas, wenn es erkennt Summer mit Warnton zusätzlich zu den RGB LEDs, die mit einem warning-status gemeldet, die in der blinkend grün grün, blinkend rot, rot.
