KQ-130F Power Line Carrier Module

Description

KQ-130F Power Line Carrier Module

Features:
The KQ-130F is designed for AC 220V / 110V, 50Hz / 60Hz strong design interference vector-based carrier transmission scheme with zero transmission effect on electric power transmission, transmission distance and so on.
The KQ-130F carrier module does not require peripheral devices, as long as a 5V power supply can be used. It has independent power supply pins, if the user needs to transmit two paths, two parallel 5V pins are required.
The KQ-130F operation includes a carrier driver, coupling, filtering, lightning protection, and many other complex peripheral circuits.
Users only need to provide a single 5V power supply, after connecting the two signal lines (TX, RX) to the microcontroller, direct connection to 220V (regardless of FireWire, the neutral line), carrier waves are transmitted through a completely transparent manner for data transmission and reception between the two AC modules.
The KQ-130F series of zero carrier data transceiver modules are based on the true meaning of zero modulation and carrier demodulation. It features anti-interference capabilities and transmission distance.

PIN Descriptions:
1P-AC: 220V AC FireWire (or neutral).
2P-AC: 220V AC to zero line (or FireWire).
3p + 5V: + 5V power supply send (260mA), if the received data can be left alone to reduce power consumption.
4P-GND: digital circuit ground.
5P- + 5V: + 5V power supply, 11mA.
6P-RX: TTL level, carrier data, MCU TXD.
7P-TX: TTL level, data support, MCU RXD.
8P-MODE: mode selection, float high at 5V, low at ground.
9P-NC / RST: reset pin (active low) when switching modes is rarely used in the workshop. This function is not necessary, the pin must be left unconnected.
KQ-130F module suitable for street lighting, smart home, fire safety, building control and other applications requiring power lines to carry data. Transmission distance up to 1.5 km.

Tutorial: How to use Floating Modem Module KQ-130F

The KQ-130F modem carrier module is ideal for anyone who wants to send data and receive messages through a GPRS connection. It is particularly useful for IoT projects or remote monitoring.

What you need

• Arduino Uno
• USB-A to B cable
• Arduino IDE software installed

Steps

1. Connect the KQ-130F module to the Arduino Uno via the TX and RX connectors.
2. Install the GPRS Shield Library in the Arduino IDE software.
3. Upload a sample sketch provided by the library to your Arduino.
4. Verify that the KQ-130F module is recognized by the computer through the Arduino IDE serial monitor.
5. Configure the module settings, such as the SIM card and GPRS network, following the documentation provided by the manufacturer.
6. Send a test message or receive data through a GPRS data connection.
7. Refer to the datasheet for detailed information on module configuration.
8. Test the stability of the connection and resolve any issues.

Example code

/*
* Esempio di codice per inviare un messaggio SMS
*/
#include <GPRS_Shield.h>
GPRS gprs;
void setup() {
 Serial.begin(9600);
}
void loop() {
 if (gprs.sendSMS("NumeroTelefonoDestinatario", "MessaggioTestuale")) {
 Serial.println("Messaggio inviato");
 } else {
 Serial.println("Errore nell'invio del messaggio");
 }
}
