MB27A - 27mm Average Continuous
MB27A - 27mm Average Continuous
The MB27A is a 27mm average continuous current inductor, specifically designed for use in high-frequency DC-DC converters, power supplies, and other IoT applications. This component is a type of passive electronic component that stores energy in the form of a magnetic field.
The primary function of the MB27A inductor is to filter and regulate the flow of electrical current in a circuit. It achieves this by opposing changes in current by generating a magnetic field, which in turn induces a voltage across the component. This voltage opposes the change in current, thereby smoothing out the flow of current and reducing electromagnetic interference (EMI).

MB27A - 27mm Average Continuous Ultrasonic Distance SensorOverviewThe MB27A is a high-accuracy ultrasonic distance sensor module, designed for precise measuring of distances in various applications, including robotics, automation, and IoT projects. This sensor module uses a 27mm transducer and provides an analog output signal, proportional to the measured distance.Technical SpecificationsMeasuring range: 20cm to 400cm (7.88in to 157.48in)
Accuracy: 1cm (0.39in)
Operating frequency: 40kHz
Supply voltage: 5V DC
Output signal: Analog voltage (0-5V)
Response time: 50ms
Dimensions: 27mm x 20mm x 15mm (1.06in x 0.79in x 0.59in)Code Examples### Example 1: Basic Distance Measurement using ArduinoIn this example, we will connect the MB27A sensor to an Arduino board and read the distance values using the analog input.```cpp
const int sensorPin = A0; // Connect MB27A output to Analog Input 0void setup() {
Serial.begin(9600);
}void loop() {
int sensorValue = analogRead(sensorPin);
float voltage = sensorValue (5.0 / 1023.0);
float distance = voltage 400.0 / 5.0; // Scale output to 0-400cm range
Serial.print("Distance: ");
Serial.print(distance);
Serial.println(" cm");
delay(50); // Wait 50ms before taking the next measurement
}
```### Example 2: Object Detection using Raspberry Pi (Python)In this example, we will connect the MB27A sensor to a Raspberry Pi and use Python to read the distance values and detect objects within a certain range.```python
import RPi.GPIO as GPIO
import timeGPIO.setmode(GPIO.BCM)
sensor_pin = 17 # Connect MB27A output to GPIO 17def read_distance():
GPIO.setup(sensor_pin, GPIO.IN)
voltage = GPIO.input(sensor_pin) 5.0 / 1023.0
distance = voltage 400.0 / 5.0
return distancewhile True:
distance = read_distance()
if distance < 50: # Detect objects within 50cm range
print("Object detected!")
else:
print("No object detected.")
time.sleep(0.5) # Take measurements at 2Hz
```Note: In this example, we assume the Raspberry Pi is configured to use the BCM (Broadcom) numbering scheme for GPIO pins. Adjust the pin numbers according to your setup.These code examples demonstrate the basic usage of the MB27A ultrasonic distance sensor module in different contexts. The sensor module can be used in a wide range of applications, including robotics, automation, and IoT projects, where precise distance measurement is required.
