Resumen
A small card used for detecting hydrogen gas in a crystal growth system by the liquid phase epitaxy technique was designed and built. Thesmall size of the card enables its portability to other laboratories where leakage detection of hydrogen or other flammable gas is required. Carddimensions are approximately 10 cm long and 5 cm wide enabling easy transportation. The design is based on a microcontroller which reads thesignal from the hydrogen sensor and internally compares the read value with preset values. Depending on the signal voltage a red, yellow or greenLED will light to indicate the levels of concentration of the flammable gas. The card is powered by a 9 V battery.
