E18-D80NK Infrared Photoelectric Switch Sensor Input Voltage: 5V Current Consumption: 25-100 mA Response time <2ms Sensor type: Diffuse reflective type Sensing range: 3-80 cm Cable length: 45 cm
Sound Sensor Module The sound sensor Module is a small board that combines a microphone (50Hz-10kHz) and some processing circuitry to convert sound waves into electrical signals. This electrical signal is fed to on-board LM393 High Precision Comparator to digitize it and is made available at OUT pin.
