IRF520 MOSFET Driver Module (0-24V) | PWM Motor & LED Controller

Original price was: ₵18.00.Current price is: ₵16.00.
The easiest way to drive 12V/24V loads. This breakout board allows your Arduino to control high-voltage devices like LED strips, DC motors, and solenoid valves using the IRF520 MOSFET. It features screw terminals for easy wiring—no soldering required!
  • Max Load: 24V DC / < 5A.

  • Control Voltage: 3.3V or 5V (PWM Compatible).

  • Output: Pulse Width Modulation (Speed/Dimming control).

  • Best For: LED Strips, Small DC Fans, and Solenoids.

MQ-3 Alcohol Sensor Module | Breathalyzer & Ethanol Detector

Original price was: ₵32.00.Current price is: ₵28.00.
Build your own Breathalyzer. The MQ-3 is specifically designed to detect alcohol (Ethanol) vapors. It has high sensitivity and fast response time, making it the perfect sensor for "Smart Car" safety systems that prevent drunk driving.
  • Detects: Alcohol, Ethanol, Benzine.

  • Sensitivity: Adjustable via Blue Potentiometer.

  • Warm-up: Heater requires ~20 seconds.

  • Best For: Breathalyzers, Drunk Driving Alarms, and Industrial Monitoring.

Soil Moisture Sensor Module (YL-69) | Automatic Plant Watering System

Original price was: ₵15.00.Current price is: ₵14.00.

Never forget to water your plants again. The Soil Moisture sensor measures the water content in soil. When the soil gets dry, the sensor output changes, allowing your Arduino to turn on a water pump automatically.

  • Outputs: Analog (Exact moisture level) & Digital (Threshold switch)

  • Adjustable: Set your "Dry" trigger point with the blue potentiometer.

  • Ideal For: Smart irrigation systems, greenhouse monitoring, and science projects.

SW-420 Vibration Sensor Module | Adjustable Impact & Shake Switch

Original price was: ₵20.00.Current price is: ₵18.00.
Detect motion, impacts, and theft. The SW-420 is a "Normally Closed" vibration sensor that triggers whenever it feels a shake. It features an onboard potentiometer to adjust sensitivity, making it perfect for sensitive projects like door alarms or earthquake detectors.
  •  Sensor Type: SW-420 (Normally Closed).
  • Output: Digital (High/Low).
  • Sensitivity: Adjustable via Blue Potentiometer.
  • Best For: Anti-Theft Alarms, Smart Cars, and Impact Detection.
