Kit Sensor de Batimentos Cardíacos ECG AD8232 para Arduino

Digital Push Button (White)

This is a DC-DC buck-mode power module, with input voltage range of 3V - 15V and fixed voltage / current at fixed 5V / 600mA . Working frequency can reach 0.5 MHz . The module has high conversion rate and small size, easy to incorporate.

This semiconductor gas sensor detects the presence of combustible gas and smoke at concentrations from 300 to 10,000 ppm. The sensor’s simple analog voltage interface requires only one analog input pin from your microcontroller.

This Flame Sensor is sensitive to the flame, but also can detect ordinary light. Usually used as a flame alarm.
