5Pcs A87 4 Channel Optocoupler Isolation Module High And Low Level Expansion Board For Arduino Description:1. Function: Use the low level to control the high level. Such as the use of single-chip 3V or 5V voltage control 9V or 12v voltage.2. HVCC should not exceed 24V. Output OUT1 / OUT2 / OUT3 / OUT4 output current equal to HVCC / 5.1K, absorption current 500ma.3. This module uses TLP281 chip (for Toshiba).4. Schematic:Input and output instructions: Input: IN1 / IN2 / IN3 / IN4, then the microcontroller or Arduino IO port, GND and the Arduino development board connected to the GND.IN1 / IN2 / IN3 / IN4 controls OUT1 / OUT2 / OUT3 / OUT4, respectively.Output: OUT1 / OUT2 / OUT3 / OUT4Output: HVCC: Connect the controlled high voltage positive, HGND connected to the controlled high voltage negativeUse: When IN1 is high, the corresponding OUT1 voltage is equal to HVCC, when IN1 is low, the OUT1 voltage is equal to HGNDUse examples The following example shows how to use the microcontroller's IO port to control the 24V motor rotation. Figure motor operating voltage of 24V,red ' ' that the motor power positive, black '-' that the motor power supply negative. When the microcontroller IO_0 output high, the motor rotate,when the IO_0 port output low, the motor stops rotating.Package included:5 x A87 4 Channel Optocoupler Isolation Module

5Pcs 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: 5 x Soil moisture detector module 5 x Probe 5 x 2P Jumper Cable
