Soil Hygrometer Detection Module / Soil Moisture Prob  

 

Product Description and Features:

1. We use high-quality soil sensors produced by our company for soil moisture detection. The surface is treated with nickel plating and has a widened sensing area, which can improve conductivity, prevent rusting in contact with soil, and extend service life.

2. The product can control the soil humidity in a wide range, and adjust and control the corresponding threshold through the potentiometer. When the humidity is lower than the set value, DO outputs a high level, and when the humidity is higher than the set value, DO outputs a low level.

3. The comparator uses an LM393 chip, which works stably.

4. Equipped with fixed bolt holes for easy installation.

5. Sensitivity is adjustable (blue digital potentiometer in the figure is adjustable)

6. Power indicator light (red) and digital switch output indicator light (green)

7. Module dual output mode, simple digital output, and more accurate analog output.

8. Working voltage 3.3V-5V

9. PCB size: 3.2cm * 1.4

 

Wiring instructions (4-wire system):

1. VCC external connection 3.3V-5V

2. GND external GND

3. DO small board digital output interface (0 and 1)

4. AO small board analog output interface

Instructions:

1. The sensor is suitable for moisture detection in soil

2. The blue potentiometer in the module is used to adjust the threshold value of soil moisture. If it is adjusted clockwise, the controlled humidity will be greater, and vice versa

3. The digital output D0 can be directly connected to a microcontroller to detect low levels and thus detect soil moisture.

Purpose:

By adjusting the soil humidity control threshold through the potentiometer, you can automatically control the soil humidity of the vegetable garden, garden automatic watering, family flower pot, various electronic competitions, electronic building blocks, design, etc.

 

 

Soil Hygrometer Control Module 5V/12V

 

Introduction:

Starting below the set humidity refers to when the soil humidity is lower than the set humidity, the relay will automatically close, start spraying, water pumps, and other positions to perform posture actions, and automatically stop when the set humidity is reached.

Purpose:

By adjusting the soil humidity control threshold through the potentiometer, it can automatically control the vegetable garden, garden automatic watering, family flower pot soil humidity, various electronic competitions, etc. It is equipped with a high-power relay, which can control the high current equipment. When the humidity is less than the setting humidity, it can automatically start the relay to pull in, when the humidity is greater than the setting humidity, it can automatically disconnect, and has a delay function to solve the problem that the relay keeps flashing in the critical state of humidity without delay, It is a simple and practical humidity control system.

 

 

 

Product Introduction:

1. We use high-quality soil sensors produced by our company for soil moisture detection. The surface is treated with nickel plating and has a wider sensing area, which can improve conductivity, prevent rusting in contact with soil, and extend service life

2. The product can control the soil humidity in a wide range, and adjust and control the corresponding threshold through the potentiometer. When the humidity is lower than the set value, start the relay to pull in, and when the humidity is higher than the set value, disconnect the relay

3. The product has a delay function, with a delay of 3-5 seconds. When the humidity is detected to be in a critical state, the relay will not flash and there will be a stroboscopic phenomenon

4. The product adopts high-quality relays, which can withstand a load of 1500W and meet the requirements of most people

5. The product has power indication and relay closing indication

 

Module usage instructions:

1. The sensor is suitable for moisture detection in soil

2. The blue potentiometer in the module is used to adjust the threshold value of soil moisture. The humidity controlled by clockwise adjustment will be larger, and the humidity controlled by counterclockwise adjustment will be smaller

3. Due to the delay function of this module, when adjusting the humidity value, it is necessary to wait for about 5-8 seconds each time to observe the changes in the relay. The green LED light also changes accordingly until it meets the requirements

 

Capacitive Soil Moisture Sensor

 

Product features:

1. A new type of soil moisture sensor, this capacitive soil moisture sensor is different from the majority of resistive sensors. It uses the principle of capacitive induction to detect soil moisture, avoiding the problem of easily corroded resistive sensors and greatly extending their working life.

2. The sensor is equipped with a built-in voltage regulator chip, which supports a wide voltage working environment of 3.3-~5.5V, which means it can work normally even on the 3.3V main control board. Micro PCs such as Raspberry Pi only require an external ADC (Analog to Digital Signal) conversion module to work.

3. With an external screen and motherboard, you can have a conversation with your plants! See if the beloved one is thirsty and needs more water to nourish it~
