ScaleSensor LX7 (Load Cell)

Other Hardware Sensors
1

Hi,

I have typical S load cell which was provided with a display, apparently ScaleSensor LX7 from scalesensor.com.

Runs on battery, which can be recharged on 110v, so north american market.

However, impossible to find any info on it except some videos on youtube Home Made Fiberglass Sheet 5/16" X 18 Bolt - Drill & Tap - YouTube

I'd like to get data from the serial port (3 wires) it has..

If anyone knows this product, I would be thankful.

Finally found it

but now I try to get the data trough RS232 with an Arduino : nothing...

#include <SoftwareSerial.h>

SoftwareSerial gtSerial(1,0); // Arduino RX, Arduino TX

void setup() {
Serial.begin(9600); // serial / USB port
gtSerial.begin(9600); // software serial port
}

byte rx_byte = 0; // stores received byte

void loop() {
// check if byte available from USB port
if (Serial.available()) {
rx_byte = Serial.read();
// send a byte to the software serial port
gtSerial.write(rx_byte);
}

// check if byte available on the software serial port
if (gtSerial.available()) {
// get the byte from the software serial port
rx_byte = gtSerial.read();
Serial.write(rx_byte);
}
}

You might destroy your Arduino if you connect it to an RS-232 interface directly. The voltage levels are not compatible. You need a driver (p.e. MAX232) for that connection.

SoftwareSerial gtSerial(1,0); // Arduino RX, Arduino TX

void setup() {
  Serial.begin(9600);    // serial / USB port
  gtSerial.begin(9600);  // software serial port
}

You cannot have a SoftwareSerial on pins 0 and 1 and use the hardware serial interface (which is on the same pins) at the same time.
