Hello Arduino Community,
I hope you're all doing well. I'm currently working on a project that involves interfacing the QNDBK1-40 Hall Effect current sensor with both an Arduino Uno and an ESP8266 microcontroller. However, I've encountered some challenges and would greatly appreciate your expertise and advice.
Issue Summary: I am attempting to integrate the QNDBK1-40 Hall Effect current sensor, which is rated for DC 1500A, with both Arduino Uno and ESP8266 platforms. My goal is to accurately measure and interpret current readings using these microcontrollers.
Specific Problems:
- Arduino Uno: I'm having trouble configuring the sensor with the Arduino Uno and reading accurate current values.
- ESP8266: Similarly, integrating the sensor with ESP8266 and ensuring reliable readings is proving to be challenging.
Request for Assistance: If anyone has experience with the QNDBK1-40 sensor or has successfully interfaced it with Arduino Uno and ESP8266, I would greatly appreciate your guidance. Specifically, I'm looking for:
- Sample code or example projects that demonstrate the integration of the QNDBK1-40 sensor with Arduino Uno and ESP8266.
- Tips on wiring, power considerations, and any specific libraries or functions that might be useful.
- (This was the code the seller gave me:(The sensor has no code
The code you said may be on the microcontroller, you can confirm with the microcontroller manufacturer.

To convert DC 0~5V voltage into digital display, you can use the analog input pin to read the voltage value and convert it into digital. Here is a simple example code that shows how to implement this function when using the ESP8266 module with Arduino:
#include <ESP8266WiFi.h>
const char* ssid = "YOUR_SSID";
const char* password = "YOUR_PASSWORD";
const int analogPin = A0; // 模拟输入引脚接在A0
int sensorValue = 0; // 保存读取到的模拟值
void setup() {
Serial.begin(115200);
// 连接到Wi-Fi网络
WiFi.begin(ssid, password);
while (WiFi.status() != WL_CONNECTED) {
delay(1000);
Serial.println("Connecting to WiFi...");
}
Serial.println("Connected to WiFi");
}
void loop() {
// 读取模拟输入引脚的电压值
sensorValue = analogRead(analogPin);
// 将0~1023的模拟值映射为0~5V的电压值
float voltage = sensorValue * (5.0 / 1023.0);
Serial.print("Analog Value: ");
Serial.print(sensorValue);
Serial.print("\t Voltage: ");
Serial.print(voltage);
Serial.println(" V");
delay(1000); // 等待1秒
}
In this example, we use analog input pin A0 to read the voltage value of 0~5V. After reading the analog value through the analogRead() function, we map it to the actual voltage value and output it through the serial port. You can view the output results through the serial monitor.
Remember to select the correct board and port in the Arduino IDE, and install the ESP8266 support library, then you can compile, upload and run this code. )
Your insights and advice would be immensely helpful in overcoming these challenges and progressing with my project. Thank you in advance for your assistance!
Best regards,
