3Pcs MAX7219 Red 8 Bit Digital Tube LED Display Module For Arduino MCU Description: MAX7219 is an integrated serial input / output common-cathode display drivers, which connects the microprocessor and 8 bit 7-segment digital LED display, you can also connect a bar graph display or 64 separate LED. Includes an on-chip type B BCD encoders, multi-channel scanning loop, segment word driver, but also a 8x8 static RAM that stores each data. Only one external register is used to set the current of each LED segment. A convenient four-wire serial interface can connect all common microprocessor. Each data can be addressed in the update without rewriting all displays. MAX7219 also allows the user to select each data encoding or no coding. The entire device includes a 150μA low-power shutdown mode, analog and digital brightness control, a scan-limit register allows the user to display 1-8 bit data, there is an all LED light detection mode. Feature: 0.36 inch Common cathode Only need three IO ports can drive 8 bit digital tube The module compatible of 5V / 3.3V microcontroller (51 / AVR / STM32...) PCV board four corners of the fixed copper stud, which can effectively precent short circuit accidents happen Wiring instructions (a program, for example, you can pick any IO port definition can be modified in the program): VCC to 5V, GND to GND, DIN to P00, CLK to P02, CS to P01 Note: VCC and GND do not reversed, it would burn the chip. 51 MCU P0 port requires pull-up resistor, if your device does not have a pull-up resistor can be connected to other ports data lines. Package included: 3 x MAX7219 8 bit digital tube module 12 x Copper pillar 12 x Screws

3Pcs Soil Hygrometer Humidity Detection Moisture Sensor For Arduino Description: This is a summary of the soil moisture sensor can be used to detect moisture, when the soil is dry, the module outputs a high level, whereas output low. Using this sensor make an automatic watering system, so that your garden plants without people to manage. Operating voltage: 3.3V~5V. Adjustable sensitivity (shown in blue digital potentiometer adjustment) Dual output mode,analog output more accurate. A fixed bolt hole for easy installation. With power indicator (red) and digital switching output indicator (green). Having LM393 comparator chip, stable. Panel PCB Dimension: 3cm x 1.5cm. Soil Probe Dimension: 6cm x 2cm. Cable Length: 21cm. 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: 3 x Soil moisture detector module 3 x Probe 3 x 2P Jumper Cable
