Product DescriptionSoil Moisture Sensor Module
This Soil Moisture Sensor Module can be used to detect the moisture of soil or judge if there is water around the sensor, let the plants in your garden reach out for human help. Insert this module into the soil and then adjust the on-board potentiometer to adjust the sensitivity. The sensor would output logic HIGH/LOW when the moisture is higher/lower than the threshold set by the potentiometer. With help of this sensor, it will be realizable to make the plant remind you: Hey, I am thirsty now, please give me some water.
Features:
Digital output, easy to adjust.
Nickel plating to avoid corrosion.
Working voltage: 3.3V-5V
On-board LM393 chip
Dimension of the board: 3.2cm * 1.4cm
YL-100 Soil Moisture Detection Sensor Module 3pin.
This module is a simple moisture sensor, use measuring moisture and humidity resistance change.
More dry soil, the smaller the output voltage. The more humid the output voltage increases.
The module will be inserted into the soil through the AD converter voltage signal can be detected in soil moisture.
With FOR Arduino, small pumps and other modules automatic watering system
Module size: 60 * 20mm
Operating voltage :3.3-5V
Output voltage: 5V power supply, about 0-3.7V (3.7V voltage is fully immersed in water)
The output voltage is for reference only, because of the different water quality factors, please actual measurements.
This module is a consumable item, will be affected by environmental corrosion, life is about 12 months.
Package Included:
Soil Hygrometer Detection Module Soil Moisture Sensor Analog Output For arduino

Reliable, No‑Mess Pads That Actually Work
Size: X-Large, Style: 40 Count
I’ve tried a bunch of different puppy pads, but these Amazon Basics ones are easily the most reliable. The 5‑layer design really does make a difference—no leaking, no soggy spots, and the quick‑dry top layer keeps my puppy from tracking wet footprints around the house. They absorb way more than I expected, and the plastic backing has never let anything seep through to the floor.
The size is perfect for daily training, and the pads stay flat instead of bunching up. My puppy took to them right away, and cleanup is super easy. For the price and the quality, these are honestly the best value pads I’ve found. Highly recommend for puppies, small dogs, or even senior dogs who need a little extra help.

They're okay-ish. Not suitable for a lot of liquid.
Size: Regular, Style: 100 Count
I use these for my opossums. They work okay-ish, but I continue to use them for the quantity and price. They're not very large animals. Make sure you are changing them out after a single pee. These really can not handle a lot of liquid. My girls both refused litter training, and so puppy pads are my only option. If your animal has large pees, I do not recommend these because it will not be able to absorb it all, and you're gonna have a mess! Thats the word I have been looking for. They can't absorb a large amount of liquid.

GOOD PRODUCT AND PRICE
Size: Regular, Style: 100 Count
The puppy pee pads are very well made at a good price. I purchased the same size pads with the same count from a competitor of Amazon, and they were more expensive, much thinner and when I tried to unfold them, some would stick together and the pads would rip.
