Designed for easy assembly and ideal for frequent travelers, it ensures your plants stay perfectly hydrated with minimal effort. ## Description Product description This is a must have tool for a connected garden! It will be helpful to remind you to water your indoor plants or to monitor the soil moisture in your garden. Through adjusting the potentiometer to control the soil humidity threshold,can automatic watering the vegetable garden, garden, control the flower pot soil moisture. Particularly suitable for people who travel frequently! Usage Test relay module: connect the relay module VCC to 5V, GND to ground, IN to GND, the relay will jump, and when IN is suspended, the relay will resume, so repeatedly, you can hear the relay "Kaka" sound. Test the soil moisture sensor module: Connect the fork probe and transmitter module with two DuPont wires. The transmitter module VCC is connected to 5V, GND is grounded. When the power is on, the red power light is always on, and the green (blue) light is flashing once. The fork probe is used. Directly inserted into the water, the green (blue) color indicator light is on. The red line of the water pump is connected to 5V, the black line is grounded, the pump works, pay attention to the test for 1 second, and it is not allowed to work in the air for a long time. Connect the system, powere on and if the pump has been working, it is correct. Because in the air, the probe can not detect the humidity, there is no problem if it is installed correctly in the pot. package listing 1xRelay module 1xMini water pump 1xPlastic Battery Storage Case Holder 1xUSB power cable 10xJumper wires 1x0.5m Vinyl Tubing 1xSoil Moisture Detector Module Review: Used it for experimenting. Worked for what I needed. Review: This took longer to put together than I expected. There are basically no instructions, and some of the writing on the relay is in Chinese, and unfortunately I can't read Chinese. So I had to search to figure out which the NO COM and NC ports were. I added a pic of the translation in case it helps someone else. The wires are extremely thin and they break easily while trying to make connections. This would have been nicer to put together if the pump wires were stripped back a little more to begin with. Turns out the wiring diagram for this is wrong. If you connect the pump's red wire to the "NO" aka Normally On port on the relay, as shown in the description picture, the pump will run when the sensor reads wet, and turn off when it reads dry. Attaching the wire to the "NC" aka Normally Closed port instead makes it work as expected. This was an interesting little project, but not suitable for someone who isn't willing to do a lot of independent problem solving. ## Features - Through adjusting the potentiometer to control the soil humidity threshold,can automatic watering the vegetable garden, garden, control the flower pot soil moisture. - Include Relay module, Mini water pump, Plastic Battery Storage Case Holder, USB power cable, Jumper wires, 0.5m Vinyl Tubing and Soil Moisture Detector Module. - Note:Do not pour water directly on the sensor. The humidity of the water will rust the sensor. - Easy assemble, make your life more automated, particularly suitable for people who travel frequently! ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07VRMRQWR | | Brand Name | AITRIP | | Control Type | Continuous variable control over soil moisture threshold | | Customer Reviews | 3.8 3.8 out of 5 stars (28) | | Fit Type | Flexible Tubing | | Hose Length | 0.5 Meters | | Manufacturer | AITRIP | | Material | Plastic | | Model Name | b7161dce-b242-4e04-9637-22f804d4b0e8 | | Model Number | b7161dce-b242-4e04-9637-22f804d4b0e8 | | Number of Pieces | 16 | | Number of Sets | 1 | | Pattern | Linear/Grid | | Plant or Animal Product Type | Plastic | | Power Source | Usb Power | | Size | 0.5 meters | | Special Features | Automatic Watering | | Style | Modern | | UPC | 701715429604 | ## Product Details - **Brand:** AITRIP - **Material:** Plastic - **Model name:** b7161dce-b242-4e04-9637-22f804d4b0e8 - **Size:** 0.5 meters - **Style:** Modern ## Images ![AITRIP Soil Moisture Sensor Kit Automatic Watering System Manager with Mini Water Pump for Arduino DIY Kit (Automatic Watering System) - Image 1](https://m.media-amazon.com/images/I/61hKXAKM7bL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by D***Y on 21 March 2020* Used it for experimenting.

The probe doesn’t work, and the usb wire serves no purpose? I replaced the probe with a better option and it works fine now. I’d say this package deal is worth 5 bucks as a mess with it and then throw it away kinda thing. But don’t trust it to water your golden apple trees ;) ## Frequently Bought Together - Soil Moisture Sensor Kit Automatic Watering System Manager with Mini Water Pump for Arduino DIY Kit (Automatic Watering System) - Arduino Uno REV3 [A000066] - ELEGOO UNO Project Super Starter Kit with Tutorial and UNO R3 Board Compatible with Arduino IDE --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/274979528-aitrip-soil-moisture-sensor-kit-automatic-watering-system-manager-mini](https://www.desertcart.be/products/274979528-aitrip-soil-moisture-sensor-kit-automatic-watering-system-manager-mini) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-05-22*
