In this project, we will make a **4-Channel Relay Driver Module Circuit** for relay based applications. In this circuit, we have designed an isolated PCB for 4 relays. By using this **Relay Board**, we can operate 4 AC appliances at a time. We have put a three pin screw terminal blocks (NC, Nuteral, NO) for connecting appliances. Below are the circuit diagram and PCB layout designs of the relay dr...
USB RS232 Relay
-------------------
The main objective of this board is to ring an school bell using a PC program written in python.
- This project is the interface of a PC to a Relay using a simple USB RS232 adapter.
- This approach was selected because the parts are easily found in any PC parts store.
- The relay is activated/deactivated using the RTS line of the serial port, any...
A Relay Circuit with 8 Channels. It needs 5V and the Signal Lines have a Resistor, so the current is limited and wont damage a Microcontroller.
Product was tested and works successful.
Seconsor controlled relay to be used for pump, main switch etc. S1 switch to be replace by magnetic water sensor (sump), photocell etc. For sump (drain pump) a timer might be needed to delay the start. This depends on the lenght of the sensor.
when you supply AC12V to this device, It will controll a relay according to the light intensity. when it's dark, the relay turns ON and when there's light it goes off.
This circuit can be very usefull since most most of the components are surface mounted and it consumes only a little amount of space.This circuit can be useful when considering saving electricity as well.You can connect this to any...
The 5V Relay Module KY-019 is perfectly made for Arduino application.
It has three pins, the VCC, GND and Signal. It can act as switch if the circuit and the load circuit have different supply voltage.
It is commonly use if the load circuit is AC. It is a switch used to connect isolated connection from the circuit using a circuit signal. It has green LED that turns on every time the coil is energi...
Soft starter for Angle grinder, Miter saw and other funny jumping during power on universal motor equipment.
Also it saves plastic gears applying less force during slow starting.
TRIAC used to soft start motor from 30% to 100% power, then relay used to feed full mains sine wave to motor. Also it supports soft stop with start/stop buttons.
Do not apply load to motor before relay latching to pre...
This is a simple circuit which controlls a relay with both LDR and PIR technology. you can supply 12v AC by connecting a 12v transformer to the 2 pinned **SCREW** header.If you dont have a transformer, you can directly connect a 6v battery to power this through the **'+DC6V' header**.
The LDR mode turns ON the relay when it's dark while the PIR mode turns ON the relay when theres a motion within...
Quick-and-dirty little circuit to switch a garbage disposal from a low-voltage momentary button. PCB fits into junction box. For supporting files, refer to https://github.com/gutschke/garbagedisposal
I couldn't find all the parts that I wanted from LCSC. For now, I linked to DigiKey parts. If you have suggestions for suitable substitute parts from LCSC, please let me know.
I made reasonable acco...
