Standard size breadboard that is perfect for prototypes. It does even have power rails on the sides to allow for more than one power level. The one you will get is white and not transparent as in the picture.Breadboard
This is the pin compatible upgrded version of the ESP-01 chip.
ESP8266 is a highly integrated chip designed for the needs of a new connected world. It offers a complete and self-contained Wi-Fi networking solution, allowing it to either host the application or to offload all Wi-Fi networking functions from another application processor.
With its size, it is probably one of the best sensor in terms of accuracy, especially considering it has an output in μg/m3 directly. if you want to use it on a raspberry pi or on a computer, but you can always use the digital or uart output directly.
This is a normally closed G1/2 12VDC electric solenoid valves with barbed inlet and outlet ports, great for projects involving low viscosity fluid control. You can find it ubiquitous on applications like automatic faucets, foot operated faucets, drinking fountains etc.
This is a digital temperature sensor, that is already calibrated. The measurement is done where the sensor is, no need for long insulated wire or complicated ADC design.
This sensor is therefore also perfect for use with a Raspberry Pi, as it is not analogic, all the data is transmitted in digital One Wire protocol.
