Pros: an almost complete set of good quality sensors by an affordable price. Cons: lacks of instructions, you need to search 37 datasheets on the internet ... OtherThoughts: You don´t need to search the 37 datasheets at the same day ... and they could include some gas sensors in the package!

Kit with various accessories, I tested all in one Arduino and it worked perfectly, just had a problem with the sometimes program.

Pros: Pretty cheap, you are getting bunch of sensors and a box for a little less more 1 dollar per item. Cons: * No english documentation. Some sensors just really lacks manuals and usage examples. * Some sensors are useless. Why do I need flame sensor? Do I need to set my room on fire to test to... Pros: Pretty cheap, you are getting bunch of sensors and a box for a little less more 1 dollar per item. Cons: * No english documentation. Some sensors just really lacks manuals and usage examples. * Some sensors are useless. Why do I need flame sensor? Do I need to set my room on fire to test it? * Most LEDs lack current limiting resistor. Сonclusion: This kit was probably intended for begginer to play with (so many different sensors and LEDs), but complete lack of english documentation makes this kit useless for begginers. But still I am satisfied, because I'm not a complete begginer and the price is good. Read more

Pros: Exactly as described, you receive 37 different Arduino-compatible sensor modules. they arrive in a sturdy, high-quality case, with removable partitions inside diving up the modules. the case was a nice unexpected bonus!

Pros: Exactly as described, you receive 37 different Arduino-compatible sensor modules. they arrive in a sturdy, high-quality case, with removable partitions inside diving up the modules. the case was a nice unexpected bonus! It comes with a list of the modules, which has the name of each module, divided by partitions in the case. Cons: No documentation whatsoever arrives with the product (in any language). the forums on this product contain most of the documentation for the items, and you can search the internet for the Keyes model to find specific modle info.

It contains many sensors, however, personally I find that many of the sensors are not very useful for me. I think it would have been better if some less useful sensors were removed from the kit and a stepper motor, or some other interesting actuator was added to the kit. After a while it gets a bit boring with blinking leds and buzzers. Read more

Pros: Great packaging, fatests delivery ever, all components seems well built and all are working perfectly with downloadable drivers cons: The only cons this far is that drivers and documentation are not in english. It is required a little surfing on the web to find doc in english.

Pro : Even for China fast shipping, and yes price is good ... Con: No documentation but was able to find in on the web

Pros: +Muy económicos. +Incluye estuche. + Están dentro de su bolsa la mayoria. +Muy buena compra. Cons: -No tiene nombre para identificarlos. -Falta algún ejemplo básico en arduino de cada uno de los sensores. Muy conforme con la compra. Recomiendo este producto. From Mexico city

Very useful set. Many different sensors. Very useful for the novice user, and for the experienced as well. With the help of these sensors can be implemented very different ideas.

Very useful for the novice user, and for the experienced as well. With the help of these sensors can be implemented very different ideas. The set contains both sensors are very simple and quite specific. The disadvantage is the lack of documentation for the sensors, or even be a parts list. My set suffered in transit. Packaging was broken. I am alone with silicone restored box sensors. With great pleasure I start to develop new systems! Perfect set at this price! Read more

There are really lots of sensors and inputs. You can do lots and lots of projects with it, they are good for DIY, because they have male pins, so if you have a female cable, you can connect they to a breadboard for easy use. Great for learning. You can find examples on the internet for both and I... There are really lots of sensors and inputs. You can do lots and lots of projects with it, they are good for DIY, because they have male pins, so if you have a female cable, you can connect they to a breadboard for easy use. Great for learning. You can find examples on the internet for both arduino and PIC examples. I own these for more than five months and was not able to use all they! Mine was one of the firsts, it did not come with a paper that indicates what sensor is what. I don't know if they are being sent now, but you can find more info in this product's forum. Buy for spare parts, experimenting, learning, anything! they are really handy and easy to use. The price is fair. If you bought they separately, it would cost more. Besides it does come with an nice box for storage. Just don't forget to put they in place after done! i lost temporarily some of they that way. Read more
