Right-Angle Liquid Water Level Float Switch (DC 220V) | Pro Tronix
MAX30100 Pulse Oximeter Heart Rate Sensor Module
“An integrated pulse oximetry and heart-rate monitor sensor solution. Ideal for wearable devices and medical monitoring projects.”
Laser Module 650NM 5V
“A compact, high-efficiency 5V laser diode module emitting a bright red dot. Perfect for security systems, laser pointers, and optical experiments.”
LM393 Infrared Slot-Type Photoelectric Speed Sensor Module
“High-precision infrared correlation sensor for counting, speed measurement, and position detection. Featuring the LM393 comparator for a clean and stable digital signal.”
“The LM393 Photoelectric Sensor is an essential module for robotics and industrial automation. It uses a 5mm wide slot to house an infrared transmitter and receiver. When an object passes through the slot and breaks the light beam, the module output changes state. This makes it perfect for measuring motor speed (RPM) or counting objects on a conveyor belt.
HC-SR501 PIR Motion Sensor Module
“High-sensitivity infrared motion sensor. Detects human or animal movement by sensing heat, making it perfect for security and smart home automation.”
Traffic Light LED Display Module
“A compact 3-color LED module simulating a real-world traffic signal. Features high-brightness Red, Yellow, and Green LEDs, making it perfect for education and smart city prototypes.”
ULN2003 Stepper Motor Driver Board Module (5V – 12V) | Pro Tronix
DFPlayer Mini MP3 Player Module
“A small and low-cost MP3 module with a simplified output directly to the speaker. It can be used as a stand-alone module with attached battery, speaker, and push buttons or used in combination with an Arduino or any other RX/TX capable microcontroller.”
