Module description 1. the module uses genuine quality relay, normally open interfaces Maximum load: AC 250V/10A, DC 30V/10A; 2. using SMD optocoupler isolation, driving ability, stable performance; trigger current 5mA; 3. the module Operating voltage 5V; 4. the module can be high or low by a jumper setting trigger; 5. fault-tolerant design, even if the control line is broken, the relay will not operate; 6. the power indicator (green), the relay status indicator (red) 7. the interface design of human nature, all interfaces are available through a direct connection terminal leads, very convenient 8. module size: 50mm*26mm*18.5mm (L*W*H) 2>. Module interface 1. DC+: positive power supply (VCC) 2. DC-: negative power supply (GND) 3. IN: can be high or low level control relay 3>. Relay outputs 1. NO: normally open relay interface 2. COM: Common Interface Relays 3. NC: normally closed relay interface 4>. High and low level trigger options It is low level trigger when jumper connect to LOW pin It is high level trigger when jumper connect to HIGH pin Soil Moisture Sensor: 1. This is a simple water sensor can be used to detect soil moisture when the soil moisture deficit module outputs a high level, and vice versa output low. Use this sensor produced an automatic plant waterer device, so that the plants in your garden without people to manage. 2. Sensitivity adjustable the blue digital potentiometer adjustment (Figure) 3. Operating voltage 3.3V-5V 4. Module dual output mode, digital output, analog output more accurate. 5. With fixed bolt hole for easy installation 6. PCB size: 3cm * 1.6cm 7. Power indicator (red) and digital switching output indicator (green) 8. Comparator LM393 chip, stable Interface Description (4-wire) 1. VCC: .3 V-5V 2. GND: GND 3. DO: digital output interface (0 and 1) 4. 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 Wholesale to save you more money! 10pcs Perfect 5V Relay SIP-1A05 Reed Switch Relay for PAN CHANG Relay 4PIN 4PCS 1/8"Plastic Electric Air Gas Water Solenoid Valve Normally Closed 12V DC 5pcs NE555 Square Wave Duty Cycle and Frequency Adjustable Module 5PCS NEW 3W White COB High Power LED Stripe LED Light Emitting Diode 10pcs 4010S 40mm x40mm x10mm Brushless DC Cooling Fan Perfect 10pcs MAX7219 Dot Matrix Module Control Display Module Cascade DIY kit Perfect 4pcs Liquid Level Controller Sensor Module Water Level Detection Sensor Perfect 2PCS NEW 30W 5730 Pure White LED Light Emitting Diode SMD 220V 85mm Perfect HOT Category On sale _Wholesale_ __Combination__ ___Sensors_ _ICs & Processors_ _Arduino_ Cables & Connectors_ LCD Modules_ Power Modules _Switches_ _ Electrical Connectors_ Valves__ __ Car Fuse__ Wireless Modules Wireless Bluetooth Relay Modules Breadboards _PCB Boards____ __LED____ ____DIYs___ ___ Resistors _ SHIPPING PAYMENT RETURNS FEEDBACK ABOUT US Address: Please make sure your Paypal address is updated and accurate.
