Very easy to work with these male to male / male to female / female to female Arduino DuPont Cable. Way easier and comfortable than making your own. Being a flat-cable flex, you can simply tear away any amount of cable for your projects, or tear each one individually for experiments. Great color coding (10 colors), good quality, decent length. No cons ... Read more
Very good product, easy to use. Detects humans outdoor located, in 15 meters distance at least. It can detect a cat in two meters. You can connect this product straight away to many projects, works great with arduino etc.. output is 3,3 V.
Easy to trim sensivity and delay. At least the capacitors should be SMD, this instrument is raher big, you see.... Read more
Easy to use with just only a transistor (or other) needed to amplify, buffer the output.
Include the control over sensitiveness and time.
Very good range and sensitive even at "middle" setting. Even a centimeter of hand movement can be detected at range of 3 meter.
Very wide angle of detection, don't need to point directly at target position ... Read more
This is one of the things you would want to have if you do home automation or alarm system. It is cheep, working perfectly and i was not able to cheat him off. Very reliable for using on Arduino like projects. Easy to use and no lag. Fast detection and i had him tested till 5m works perfectly. Different settings on its own. All you need is to make some ...

Very good product, easy to manipulate. Detects an human located in 4 meters at least (tested indoor) in about 1 sec (in all directions). Good for domotic apps (auto light turning on...) The white part was broken, but it works. The 3 black pins were also twisted, but they were easily corrected with pliers. Datasheet and connexion informations are not ... Read more
There is no documentation for it. Google HC-SR501. You can connect CdS light sensor in it. It has two potentiometers and jumper pads so you can setup to suit your needs. Would be nice if a datasheet was available. But you don't really expect that from these kinds of assembled components. Google HC-SR501 Works very well and is cheap. Get one even if ... Read more
Trabaja con una gran perfección no se le escapa ningun movimiento y la alimentacion puede funcionar incluso con menos de lo indicado en caracteristicas, los reguladores estan al 50% por lo que da juego a cambiarlos a nuestras necesidades la carcasa de plastico no va fijada y se puede caer al estar boca abajo. tutorial de funcionamiento de este ...

Very small - you can set it up everywhere. Can use low voltage power - even USB Have 2 resistor for tune in sensitivity. Price is affordable. Board could be smaller If device so small - they should use SMD capasitors It would be great to have digital in\out on it - I2C or rs232. 1 on\off pin is good, but not enought. Great device - you can build your ... Read more
This is one of the fun items to use with your development board or in an actual application. There is enough information on the internet on how to connect, how to install light sensor, how to install temperature compensation for high ambient temperature. Also found the Eagle schematics and board layout. There is also documentation (of course not from ... Read more
Small Size, detects motion from 5+ feet which i tested, trimpots given for changing the sensitivity. The Plastic Lens case is very lightly attached.
No datasheet provided in specifications
Capacitors should have been SMD the Packaging should have been BETTER, as this can be easily damaged in transit. The Lens is NOT actual FRESNEL I think... there are ... Read more
