SparkFun Atmospheric Sensor Breakout – BME280 (Qwiic): The SparkFun BME280 Atmospheric Sensor Breakout is an easy way to measure barometric pressure, humidity, and temperature readings, all without taking up too much space. SparkFun Indoor Air Quality Sensor – ENS160 (Qwiic): The SparkFun ENS160 Indoor Air Quality Sensor is a digital multi-gas sensor solution with four sensor elements that can be used in a wide range of applications including building automation, smart home, and HVAC. SparkFun Capacitive Touch Slider – CAP1203 (Qwiic): This little board acts great as a non-mechanical button. Use the three pads on the board or connect your own input for a great touch button or slider with no moving parts. Flexible Qwiic Cable (100 mm): Use these to connect up to four Qwiic boards in your kit. RGB and Gesture Sensor (APDS-9960): This board does a little bit of everything. You can measure ambient light or color as well as detect proximity and do gesture sensing all over I2C. Soil Moisture Sensor (with screw terminals): Ever wonder if your plant needs water? This sensor outputs an analog signal based on the resistance of the soil. Since water is conductive, the soil water content will be reflected in the soil resistance. Sound Detector: Ever need to know if there is noise in an area? This board will not only tell you, but it will also output amplitude as well as the full audio signal. Break Away Headers (Straight): Solder these pins to any of the breakouts to prototype on a breadboard. You'll want to solder these to boards that do not have Qwiic connectors such as the gesture sensor and sound detector.
