Communication Interface: I2C (compatible with 3.3V and 5V systems)Code Examples### Example 1: Basic Voltage Measurement with ArduinoThis example demonstrates how to use the DT9205A Digital Multimeter to measure voltage using an Arduino board.```cpp
#include <Wire.h>#define DT9205A_I2C_ADDRESS 0x1E // I2C address of the DT9205Avoid setup() {
Wire.begin(); // Initialize I2C communication
Serial.begin(9600); // Initialize serial communication
}void loop() {
byte data[2];
Wire.beginTransmission(DT9205A_I2C_ADDRESS);
Wire.write(0x00); // Select voltage measurement mode
Wire.endTransmission();
Wire.requestFrom(DT9205A_I2C_ADDRESS, 2);
data[0] = Wire.read();
data[1] = Wire.read();
int voltage = (data[0] << 8) | data[1];
float voltageValue = voltage 0.01; // Convert to volts
Serial.print("Voltage: ");
Serial.print(voltageValue);
Serial.println(" V");
delay(1000); // Measure every second
}
```### Example 2: Resistance Measurement with Raspberry Pi (Python)This example demonstrates how to use the DT9205A Digital Multimeter to measure resistance using a Raspberry Pi and Python.```python
import smbus
import time# Set up I2C communication
bus = smbus.SMBus(1)# DT9205A I2C address
DT9205A_I2C_ADDRESS = 0x1Edef read_resistance():
# Select resistance measurement mode
bus.write_byte(DT9205A_I2C_ADDRESS, 0x03)
# Read resistance data
data = bus.read_i2c_block_data(DT9205A_I2C_ADDRESS, 0x00, 2)
# Convert data to resistance value
resistance = (data[0] << 8) | data[1]
resistanceValue = resistance 0.1; // Convert to ohms
return resistanceValuewhile True:
resistance = read_resistance()
print("Resistance: {:.1f} ohms".format(resistance))
time.sleep(1) // Measure every second
