Component Documentation: 12V 0.18A CPU Cooling FanOverviewThe 12V 0.18A CPU Cooling Fan is a compact and energy-efficient fan designed to provide reliable cooling for CPUs, GPUs, and other components in IoT devices. This fan operates at a voltage of 12V and consumes 0.18A of current, making it an ideal solution for battery-powered or low-power IoT applications.Technical SpecificationsVoltage: 12V
Current: 0.18A
Power: 2.16W
Speed: 2500 RPM
Airflow: 12.6 CFM
Noise Level: 25 dBA
Connector: 3-pin JST XH2.54mm
Dimensions: 40mm x 40mm x 20mm
Weight: 60gHardware ConnectionsThe fan has a 3-pin JST XH2.54mm connector, which can be connected to a compatible power source and control circuitry. The pinout is as follows:Pin 1: VCC (12V)
Pin 2: GND
Pin 3: PWM (optional)Code Examples### Example 1: Simple Fan Control using ArduinoIn this example, we will control the fan using an Arduino board and a simple switch. The fan will turn on when the switch is pressed and turn off when the switch is released.```cpp
const int fanPin = 9; // PWM pin for fan control
const int switchPin = 2; // Digital pin for switch inputvoid setup() {
pinMode(fanPin, OUTPUT);
pinMode(switchPin, INPUT);
}void loop() {
int switchState = digitalRead(switchPin);
if (switchState == HIGH) {
digitalWrite(fanPin, HIGH); // Turn on the fan
} else {
digitalWrite(fanPin, LOW); // Turn off the fan
}
delay(50);
}
```### Example 2: Fan Speed Control using Raspberry Pi and PythonIn this example, we will control the fan speed using a Raspberry Pi and Python. The fan speed will be adjusted based on the temperature reading from a DS18B20 temperature sensor.```python
import RPi.GPIO as GPIO
import time
import os# Set up GPIO pins for fan control and temperature sensor
fan_pin = 18
temp_sensor_pin = 4GPIO.setmode(GPIO.BCM)
GPIO.setup(fan_pin, GPIO.OUT)while True:
# Read temperature from DS18B20 sensor
temp = os.popen("cat /sys/bus/w1/devices/28-00000724a409/temp").read()
temp_c = float(temp) / 1000.0# Adjust fan speed based on temperature
if temp_c > 40:
fan_speed = 100 # Full speed
elif temp_c > 30:
fan_speed = 50 # Half speed
else:
fan_speed = 0 # Turn off the fan# Set fan speed using PWM
GPIO.output(fan_pin, GPIO.HIGH)
time.sleep(fan_speed / 100.0)
GPIO.output(fan_pin, GPIO.LOW)
time.sleep((100 - fan_speed) / 100.0)
```These examples demonstrate how to use the 12V 0.18A CPU Cooling Fan in various IoT applications. The fan can be controlled using a microcontroller, single-board computer, or other devices that provide a compatible power source and control interface.
