Product use: Through the potentiometer adjusting soil moisture threshold control, automatic in garden, garden automatic watering, family flowerpot soil humidity control, all kinds of electronic games, with high power relay, can control large current device, less than setting humidity automatic start relay, greater than setting humidity automatically disconnect and delay function, without delay of critical humidity state relay don't stop flicker problem solving is a simple and practical soil humidity control system. Product introduction: 1. Using the company's production of high-quality soil sensor for detection of soil moisture, and the surface of the nickel plating, widening of the sensing area can improve conductive properties, prevent soil contact is easy to rust, prolong service life; 2. The product can be a wide range of control soil humidity and control the corresponding threshold value by adjusting the potentiometer and the humidity is lower than set value, start relay, is higher than the set value, the relay is switched off. 3. Product with the function of time delay, delay 3-5 seconds when detected humidity in the critical state, relay will not blink, stroboscopic phenomenon; 4 products using high quality relay, can withstand the load of 1500W, to meet the requirements of most people; 5 products with power indicator and indicator relay; Electrical parameters: Supply voltage: 5VDC input current: more than 100mA Load: 10A 250V AC or 10A 30V DC (lower than the current in this range can be used) Module instruction: 1 sensors applied to the detection of soil moisture; Module 2. Blue potentiometer is used to soil moisture threshold adjustment, clockwise adjustment and control the humidity will be bigger, counterclockwise smaller; 3 due to the module with delay function, adjust the humidity value, once every tune need to wait about 5-8 seconds, see the change of the relay, the green LED lamp also has the corresponding change, until adjusted to meet the requirements.

Disclaimer: 1 This is a summary of the moisture sensor can be used to detect the moisture of the soil, when the soil is dry , the module outputs a high level , whereas the output low. Using this sensor make an automatic watering system , so that your garden plants need people to manage . 2 adjustable sensitivity ( shown in blue digital potentiometer adjustment ) 4 Operating Voltage 3.3V-5V 5 Module Dual Output mode , a simple digital output , analog output more accurate. 6 with fixed bolt hole for easy installation 7 small PCB board size : 3cm * 1.6cm 8 power indicator ( red ) and the digital switch output indicator ( green ) 9 using LM393 comparator chip , stable VCC external 3.3V-5V GND GND External DO small board digital output interfaces ( 0 and 1 ) AO small board analog output interface Instructions A soil moisture and humidity module most sensitive to the environment , usually used to detect soil moisture . Modules in the soil moisture reach the set threshold , DO port output high when soil moisture exceeds a set threshold, the module D0 output low ; Digital outputs D0 small plates can be directly connected with the microcontroller through the microcontroller to detect high and low , thereby detecting soil moisture ; Small plates digital output DO OUR relay module can directly drive the buzzer module , which can be composed of a soil moisture alarm equipment ; Small plates AO analog output modules can be connected and AD through the AD converter , you can get a more accurate value of soil moisture ;
