NTC Thermistor Sensor Module
Raindrop Sensor Module | Rain & Water Detector for Arduino
Build your own weather station. This sensor detects rain, snow, or water droplets. It consists of a large nickel-plated sensing board and a control module. When water hits the board, it sends a signal to your Arduino to close windows or sound an alarm.
-
Sensor Type: Resistive (Nickel-Plated Board).
-
Outputs: Digital (High/Low) and Analog (Rain Intensity).
-
Durability: Treated against oxidation for longer life.
-
Best For: Automatic Wipers, Smart Clotheslines, and Weather Stations.
RC522 RFID Reader / Writer Module 13.56MHz with Cards
Soil Moisture Sensor Module (YL-69) | Automatic Plant Watering System
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.
Sound Sensor Module (Microphone) | Clap Switch & Alarm Detector
Turn on lights with a clap! This microphone module detects sound waves and converts them into a digital signal for your Arduino. It is the core component for "Clap Switch" projects and noise-activated alarms.
-
Sensitivity: Adjustable via Blue Potentiometer.
-
Outputs: Digital (Gate) and Analog (Waveform).
-
Microphone: High-Sensitivity Condenser Mic.
-
Best For: Clap Switches, Baby Monitors, and Noise Alarms.
SW-420 Vibration Sensor Module | Adjustable Impact & Shake Switch
- 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.
