* Specs

1, the module complies with international safety standards, the load control area and regional isolation tank; 

2, using loose music authentic relay; 

3, with the power and relay instructions, pull off, disconnect does not shine; 

4, when the input signal is a signal, often beginning with a common terminal will be turned on; 

5, can be used as a microcontroller development board module that can be used as home appliance control; 

6, the control DC or AC signal, you can control 220V AC load; 

7, there is a normally open and one normally closed contact; 

8, blue KF301 terminals to the control line is more convenient. 

About  the high and low trigger description.if you don't understand .pls check below 

Means there is a high trigger voltage trigger, can be understood as a way to signal input terminal and VCC between the positive short trigger signal input and ground; 

Refers to a low voltage trigger signal input terminal and ground for OV trigger mode, can be understood as a way to signal input terminal and GND short circuit triggered the negative

5V Relay Module (KY-019) [S076]

https://www.youtube.com/watch?v=nW7LC4X-6sc

*GitHub : https://github.com/rdiot/rdiot-s076.git

* Specs

The company produces relay module can be connected to 240V AC or 28V DC power into a variety of other electrical parts. The relay can be used in anti-theft alarm, toys, etc. Relay is an electrically controlled device. It has a control system (also known as the input circuit) and the control system (Also known as the output circuit).

Commonly used in automation control circuit, it is actually a small Current to control a large current operation "automatic switch." Therefore, the circuit automatically adjusts the play, safety protection, transfer Conversion circuit and so on. Particularly suitable for single-chip control strong electric devices. In the control and use is also very convenient, just give input corresponding output relay different levels, you can Achieved by controlling the relay control purposes other devices, in addition, in the multi-channel relay PCB layout on the use of two lines Layout, user-lead connections. While in the circuit of a DC diode added greatly improved relay

Module to engage current ability to prevent the transistor being burned. In addition, we added a relay this power indicator Lights (except relay all the way), the indicator is red. In brightest relay also adds a status indicator.
