I wanted to be able to control my projects not only from my local WiFi network, but from anywhere in the worl simply by using a web . Find this and other hardware projects on Hackster. Will be danergerous to use in any other cases. Use mature AC-DC power module, input.
Its a small and dirt cheap device which has a inbuilt controller. For home automation, a switch with multiple relays can come in handy.
You may be working with LIVE MAINS! Source code will be provided. For more information see the and Instructable links below. Here is an instructable.
I think its really interesting for its compact size. To create out IoT power switch, we just need to swap out the green LED for our solid state relay , and connect all the wires. Aptinex IOT channel relay module is the first IOT related device manufactured by Aptinex along with many other oncoming IOT devices.
The main objective of Team Aptinex in designing this was to ease the controlling applications related to smart home ,lighting etc.
I have several of these modules. They have an optional opto-isolator built-in, but you have to remove the jumper to use it. If your relay coil can operate a little bit below 5V you can probably use the USB 5V supply to power it.
Fortunately, eBay offers a wide variety of relays suitable to be controlled by a microcontroller, as can . Disclaimer: AC mains can kill. This is not an instructional exercise. Solder voltage regulator BA033.
Before soldering I scratched electronic path in places and 3: To solder pinout to board you have to add piece of wire. Alexa, Wifi Cams motion detection. I used wire from resistor. Tested with 220V, but as usual, everything is your responsibility. At start up the LED will blink twice once the . Setting GPIOhigh, causes the relay to close the NO contact with Common and the NC contact to open.
Additionally, taking connector “G” high causes GPIOto also go low isolated via a PC8photocoupler. On my board the blue LED is . The code is written with Arduino IDE. The both have a similar size.
They might look alike but they are actually quite different from the inside.
