Humidity and Temperature Sensor Module
Features
- DHT22 Is a compound digital temperature and humidity sensor which outputs calibrated digital signals. Thanks to the dedicated digital module acquisition technology and temperature and humidity sensing technology applied to the module, dht22 comes with very high reliability and excellent long-term stability.
- DHT22 Includes a capacitive moisture sensor and a NTC temperature measuring element which is connected to a high-performance 8-bit microcontroller, resulting an excellent quality, super fast response time, strong anti-interference ability and extremely cost-efficient.
- Compared with sht10 temperature and humiditiy sensor, DHT22 Enjoys a higher precision and lower price, Making it an ideal choice for mid price range, high performance temperature & humidity sensors.
- If used together with arduino expansion boards, you'll easily get interactives of correlation between temperature and humidity perception.
- Note : DHT22 Digital temperature and humidity sensor is designed for analog sensor interfaces. the analog interface is used as a digital one which will not occupy other digital interfaces on the arduino. you can also use the analog-to-digital-converting cable to connect DHT22 to digital interfaces.
- Ultra-low power
- No additional components
- Excellent long-term stability
- All calibration, digital output
- Completely interchangeable
- Long distance signal transmission
- Relative humidity and temperature measurement

Great for Puppies!
Color: Red
This toy has been a great purchase for my new puppy! He has so much fun playing with it and stays engaged for long periods. While it can move a little fast at first, the adjustable speed settings make it easy to customize. Overall, it’s a fantastic toy that keeps him active, entertained, and happy.

Good for (non-destructive) small dogs
Color: Red
Bought for a small dog, would not recommend for a destructive chewer. After some initial hesitation this has become her favorite toy and keeps her entertained for a good while. The different settings provide some variety to how she can play with it. The battery only lasts about an hour, but it does charge quickly. As others have noted the string is garbage.

Cool gadget for you puppy!
Color: Red
Do you need a break sometime? Something that you puppy can play with for 20 or 30 minutes at a time? This is it! It goes around the place in random paths that will keep your puppy entertained and amusedZ. It not to loud and it lasts a long time and nothing has broken off form the rough play at all.

Great for small dogs with a big prey drive!
Color: Red
He loves it!! I have a small dog with a big prey drive and he goes absolutely crazy for this! A big plus for taking the boredom away, really perking up his mental attitude. It's also (at this moment) much cheaper than others that look very similar. Super easy to charge. My dog is a rescue and never learned to play with toys, has zero interest in stuffed toys and doesn't really understand play, but this isn't play to him: It's what he was born to do. He gives it a hearty Two Paws Up!

Our Yorkie Puppy Loves This Toy!!!
Color: Red
Warning: your pet may become completely obsessed
I’ve had this toy for about a year for my Yorkshire Terrier, Gia, and it’s easily the most successful toy purchase I’ve ever made. We even had to replace the first one after she loved it a little too much (chewed the string off), and have since bought more as gifts for friends’ pets. Great toy for small dogs (too fragile for bigger dogs) and active, young cats.)
What we love:
* Endless engagement: Gia ignores all her other toys and goes straight for this every time
* Interactive features: Subtle beeping + changing colored lights + unpredictable rolling patterns keep her hooked
* Energy burner: Perfect for indoor play on hardwood floors—she will chase it nonstop
* Rechargeable: Battery lasts several hours, even with frequent use
* Durability: Holds up well considering how rough she plays
Real-life note:
Gia will literally bring this toy to me to get me involved—and I have to limit her playtime because she won’t stop on her own.
Bottom line:
If you have a high-energy dog (or even a playful cat), this isn’t just a toy—it becomes their favorite activity… and possibly their entire personality.
