If you want to make some home automatizations this is the product you want! It just receives a 5V signal (the one from most microcontrolers) and it activates a switch between 120 o 240 V so you sould turn on anything with a microcontroler. Read more
Good item for a small price.
Like its qulity and easy use with arduino.
there are 3 pins to connect:
NC, opt, NO
NC is for always closed, NO is for always opened.
So if you want to close relay and make it works, connect one part of a cable to opt (the middle one) and another one to NO or NC depending ... Read more
This is a very practical relay to be used with Arduino and relative boards. If you are looking for a one-channel relay, this is the option.
Only 3 wires: Vcc, Gnd and the Signal wire, which activates the relay. Read more
Awesome. Works as a part of Bluetooth controlled lightswitch in my home and I have to say it's just perfect. Pros:
- compatibility with Arduino, Atmega xx, ATTiny xx microcontrollers.
- unfortunately it emits sound wich can be a little bit annoying but normally noise in the house is drowning ... Read more
Este relé es completamente compatible con Arduino u otros microcontroladores. Trae ya consigo toda la circuitería necesaria para que funcione, por lo que sólo deben aportarse un par de cables para que funcione. Trabaja a 220V sin problemas, siendo controlado por un Arduino. Pros: Circuitería ya integrada ... Read more
Pros: Works good, i used it with a 3V3 mini computer connenction like raspberry pi, olimex and Beaglebone black, I used several of these devices, even with a PIC controller to make a realy small smart relay. It isn't to complex device it just must make a contact when a small voltage is supplied, but ... Read more
I ordered two of this modules to work with my arduino, and at first I was amazed of this products working so well with the arduino in fact, it will never let you down, at least as far as I've worked with this module. Just and advice, you must get a cable male to female to use this module with the arduino,... Read more
