VCC: 3.3V-5V. GND: GND. DO: digital output interface(0 and 1). AO: analog output interface. Instructions for Use: 1. Soil moisture module is most sensitive to the ambient humidity is generally used to detect the moisture content of the soil. 2. Module to reach the threshold value is set in the soil moisture, DO port output high, when the the soil humidity exceeds a set threshold value, the module D0 output low. 3. The digital output D0 can be connected directly with the microcontroller to detect high and low by the microcontroller to detect soil moisture. 4. The digital outputs DO shop relay module can directly drive the buzzer module, which can form a soil moisture alarm equipment. 5. Analog output AO and AD module connected through the AD converter, you can get more precise values of soil moisture. Package Included: 10 x Soil moisture detector module 10 x Probe 10 x 2P Jumper Cable

10Pcs CJMCU-MCP4725 I2C DAC Breakout Development Board Module Description: You’ve always wanted to output analog voltages from a microcontroller, the MCP4725 is the DAC that will let you do it! The CJMCU-MCP4725 is an I2C controlled Digital-to-Analog converter (DAC). A DAC allows you to send analog signal, such as a sine wave, from a digital source, such as the I2C interface on the Arduino microcontroller. Digital to analog converters are great for sound generation, musical instruments, and many other creative projects! This version of the CJMCU-MCP4725 Breakout fixes a few issues with the board including the IC footprint, the I2C pinout, changes the overall board dimensions to better fit your projects, and a few more minor tweaks. This board breaks out each pin you will need to access and use the MCP4725 including GND and Signal OUT pins for connecting to an oscilloscope or any other device you need to hook up to the board. Also on board are SCL, SDA, VCC, and another GND for your basic I2C pinout. Additionally, if you are looking to have more than one MCP4725 on a bus, the pull-up resistors on this board can be disabled just check the Hookup Guide in the Documents section below for instructions and tips on doing this. Feature: 12-bit resolution I2C Interface (Standard, Fast, and High-Speed supported) Small package 2.7V to 5.5V supply Internal EEPROM to store settings Package included: 10 x CJMCU-MCP4725 I2C DAC Breakout Development Board Module

10Pcs 5V 16M ATmega328P Arduino Compatible Version LilyPad 328 Main Board Description: The Arduino Compatible LilyPad is a microcontroller board designed for wearables and e-textiles. It can be sewn to fabric and similarly mounted power supplies, sensors and actuators with conductive thread. The board is based on the ATmega328 with the Arduino bootloader. The main board has a minimum number of external components to keep it as small (and as simple) as possible. The latest version supports automatic reset for even easier programming. The back side of the LilyPad is completely flat. It uses a surface mount programming connector, which keep the header from poking through. Specification: Microcontroller: ATmega328P Operating voltage: 2.7V ~ 5.5V (recommended 5V) Input voltage: 2.7V ~ 5.5V (recommended 5V) Digital I/O pins: 14 (of which 6 provide PWM output) Analog input pins: 6 DC current per I/O pin: 40mA Flash memory: 16KB (of which 2KB used by bootloader) SRAM: 1KB EEPROM: 512bytes Clock speed: 16MHz Note: Don't power the LilyPad Arduino with more than 5.5V, or plug the power in backwards: you'll kill it. Package included: 10 x Arduino compatible LilyPad ATmega328P
