This 12-inch (30-cm) cable has 26 AWG wires with a 3-pin female JST PH-style connector that works with Sharp analog distance sensors that have mating PH connectors. The other ends of the wire are terminated with male pins for 0.1" housing. The wire color scheme matches the Sharp distance sensor pinout: red for power, black for ground, and white for signal.
This 7 segment LED Keypad Shield is an Arduino LCD Shield with a 4 digit 7 segment digital tube display (common cathode). It has 5 buttons that can be used as menu select buttons or control buttons, using I2C to drive the digital tube for an easy user experience.
The A-Star 32U4 Micro is a tiny programmable module featuring Atmel’s ATmega32U4 microcontroller. It packs a Micro-USB interface and 18 digital input/output pins (of which 7 can be used as PWM outputs and 8 as analog inputs) onto a board measuring only 1? × 0.6? and ships preloaded with an Arduino-compatible bootloader.
The CCS811 Air Quality Breakout is a digital gas sensor solution that senses a wide range of Total Volatile Organic Compounds (TVOCs), including equivalent carbon dioxide (eCO2) and metal oxide (MOX) levels. VOCs are often categorized as pollutants and/or sensory irritants and can come from a variety of sources.
The turbidity sensor detects water quality by measuring level of turbidity. It is able to detect suspended particles in water by measuring the light transmittance and scattering rate which changes with the amount of total suspended solids (TSS) in water.
The Arduino Uno Wi-Fi is the new Arduino Uno with an integrated Wi-Fi module! The board is based on the ATmega328P (datasheet) with an ESP8266 Wi-Fi Module integrated (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator.
