This Moisture Sensor can be used to detect the moisture of soil or judge if there is water around the sensor, let the plants in your garden reach out for human help. They can be very to use, just insert it into the soil and then read it. With help of this sensor, it will be realizable to make the plant remind you : Hey, I am thirsty now, please give me...
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 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.
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.
The Arduino Mega 2560 is a microcontroller board based on the ATmega2560 (datasheet). It has 54 digital input/output pins (of which 14 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the...
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. There is an USB Uart converter included 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.
