Shipping
We are an online wholesale platform and shipping costs are charged separately for greater benefit to you.
Air freight costs are based on the weight of the product (including packaging bags and cushioning materials). For products under 2kg, freight is calculated in 50g increments. For products between 2kg and 4kg, freight is calculated in 100g increments. For products over 4kg, freight is calculated in 1kg increments.
If your order exceeds 4kg or the shipping cost exceeds $70, we recommend contacting our customer service for an accurate shipping quote. You will need to provide your zip code address when you contact us.
Air freight options include DHL, UPS, FedEx, and Yun Express, with a delivery time of 7-12 days.
When the weight of the express delivery exceeds 12kg or air shipping cost exceeds US$100 or sea shipping cost exceeds US$50, you can choose B2B shipping:
Air freight(10-14 days)
Yun quik boat sea freight (15-20 days)
Quik boat sea freight(20-25 days).

Processing starts after your payment confirmed. Normally, it needs 2-5 days. The processing time depends on the quantity of items.
1. This is a simple moisture sensor used to detect soil moisture. When the soil is dry, the module outputs a high level; conversely, it outputs a low level. Use this sensor to create an automatic watering device, allowing you to manage your garden plants without human intervention.
2. Adjustable sensitivity (adjustable by the blue digital potentiometer in the image).
3. Operating voltage: 3.3V-5V
4. Dual output modes: simple digital output and more accurate analog output.
5. Equipped with mounting bolt holes for easy installation.
6. PCB size: 3cm * 1.6cm
7. Power indicator (red) and digital switch output indicator (green).
8. The comparator uses an LM393 chip for stable operation.
PCB Interface Description (4-wire)
1. VCC: External 3.3V-5V
2. GND: External GND
3. DO: Digital output interface (0 and 1)
4. AO: Analog output interface
Instructions for Use
1. The soil moisture module is most sensitive to ambient humidity and is generally used to detect soil moisture.
2. When soil moisture falls below the set threshold, module D0 outputs a high level; when soil moisture exceeds the set threshold, module D0 outputs a low level.
3. The small board's digital output D0 can be directly connected to a microcontroller, which detects high and low levels to determine soil moisture.
4. The small board's digital output DO can directly drive our relay modules, buzzer modules, etc., thus forming a soil moisture alarm device.
5. The small board's analog output AO can be connected to an AD module; through AD conversion, a more accurate soil moisture value can be obtained.
