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

Really cool cat toy for even the most picky cat!
Color: A1-Red, Color: A1-Red
I love it, wow. Our cat is picky with toys, but even he was intrigued by it. It really kept his attention, which is hard to do. It comes with three modes: fast, slow, and interactive. The only thing is that hair can get all trapped up in it because it's a wheel, so keep your house clean I guess lol. The tail also came off once, so you gotta snuggly get it on up there. Really cool cat toy though, I'm happy I got it lol

Not worth the money
Color: A1-Red
My small Chihuahua loved this toy. It kept him entertained until it would stop working. He only gets about 10 minutes of play and it's no longer charged to use. I even bought a second one thinking the first one might have been just bad luck, but nope, the same problem. It seems most of these interactive toys are only given 2 to 3 stars. I'm disappointed but more importantly, my pup is even more.

Terrific product
Color: A1-Red
I adopted a 2 year old cat - she’s not much for a lot of the toys I have purchased for her, until this one! At first she seemed very cautious with it - but still followed it around - once I slowed it down (a few different options) she loves to play with it! Great purchase very pleased with it

Fun & Fast moving toy for my cats!
Color: A1-Red
This is such a fun little toy to keep my cats entertained. They were definitely weary about it for the first few days, but started to get used to it and play with it after a bit. I wish there was an even slower option because the slow option is still pretty fast, but at least it gets them up and moving. They will even play with the tail part when it's not turned on. Like others have said, it does collect hair pretty easily, but it's very easy to clean off. I don't have any dogs, but I could see smaller dogs loving this as well!

That it’s usable for more than one day
Color: A3-Pink, Color: A3-Pink
The toy itself is great and my puppy enjoyed it. My problem is that it didn’t come with a charging cord and none of mine fit. It never changed colors. Maybe if I had a charger cord it would be worth it, but right now it’s useless!!
