MetroQ MTQ 1010D Digital Lux Meter Pinout Explanation
The MetroQ MTQ 1010D Digital Lux Meter is a compact, high-accuracy lux meter module designed for measuring illuminance in various applications. The module features a 6-pin interface, which is explained in detail below:
Pinout Structure:
The MetroQ MTQ 1010D Digital Lux Meter has a 6-pin interface with the following pinout structure:
| Pin No. | Pin Name | Description |
| --- | --- | --- |
| 1 | VCC | Power Supply (3.3V to 5.5V) |
| 2 | GND | Ground |
| 3 | SCL | I2C Clock Signal |
| 4 | SDA | I2C Data Signal |
| 5 | INT | Interrupt Output |
| 6 | NC | Not Connected (Reserved) |
Pin-by-Pin Explanation:
1. VCC (Power Supply):
This pin is used to provide power to the MetroQ MTQ 1010D Digital Lux Meter module. The recommended operating voltage range is 3.3V to 5.5V. It is essential to ensure the power supply is stable and within the specified range to maintain accurate measurement readings.
2. GND (Ground):
This pin is connected to the ground plane of the system. It provides a reference point for the module's internal circuitry and helps to reduce noise and interference.
3. SCL (I2C Clock Signal):
This pin is used for the I2C (Inter-Integrated Circuit) clock signal. I2C is a serial communication protocol used for communication between the microcontroller and the lux meter module. The SCL pin provides the clock signal for data transmission.
4. SDA (I2C Data Signal):
This pin is used for I2C data transmission. The SDA pin transmits data between the microcontroller and the lux meter module.
5. INT (Interrupt Output):
This pin is an active-low interrupt output that signals when a new measurement is available. When a new measurement is ready, the INT pin goes low, indicating that the data can be read from the module.
6. NC (Not Connected/Reserved):
This pin is reserved and should not be connected. It is not used in the current version of the module and may be used for future updates or features.
Connection Guidelines:
When connecting the MetroQ MTQ 1010D Digital Lux Meter module to your microcontroller or system, ensure the following:
Connect VCC to a stable power supply (3.3V to 5.5V) using a suitable voltage regulator or a battery.
Connect GND to the ground plane of the system.
Connect SCL to the I2C clock pin of the microcontroller.
Connect SDA to the I2C data pin of the microcontroller.
Connect INT to an interrupt-enabled pin of the microcontroller, if desired (optional).
Leave the NC pin unconnected.
Proper connection and handling of the pins are crucial to ensure accurate and reliable measurements from the MetroQ MTQ 1010D Digital Lux Meter module.

In this example, we will connect the MetroQ MTQ 1010D to an Arduino Uno board to measure the ambient light level.

```
#include <Wire.h>

#define MTQ1010D_ADDRESS 0x38 // Default IC address of the MetroQ MTQ 1010D

void setup() {
  Serial.begin(9600);
  Wire.begin(); // Initialize IC communication
}

void loop() {
  int lux = readLux();
  Serial.print("Ambient light level: ");
  Serial.print(lux);
  Serial.println(" lux");
  delay(1000);
}

int readLux() {
  Wire.beginTransmission(MTQ1010D_ADDRESS);
  Wire.write(0x00); // Send command to read lux value
  Wire.endTransmission();
  Wire.requestFrom(MTQ1010D_ADDRESS, 2); // Receive 2 bytes of data
  int highByte = Wire.read();
  int lowByte = Wire.read();
  int lux = (highByte << 8) | lowByte;
  return lux;
}
```

### Example 2: Using the MetroQ MTQ 1010D with Raspberry Pi (Python)

In this example, we will connect the MetroQ MTQ 1010D to a Raspberry Pi board to measure the ambient light level using Python.

MTQ1010D_ADDRESS = 0x38 // Default IC address of the MetroQ MTQ 1010D

while True:
    bus.write_byte(MTQ1010D_ADDRESS, 0x00) // Send command to read lux value
    data = bus.read_i2c_block_data(MTQ1010D_ADDRESS, 2) // Receive 2 bytes of data
    lux = (data[0] << 8) | data[1]
    print("Ambient light level: ", lux, " lux")
    time.sleep(1)
```
