Sensors

About

Sensors are the eyes and ears of any embedded system, converting real-world physical phenomena into electrical signals that microcontrollers can measure, process, and act upon. From light and magnetic field detection to ultrasonic ranging, our sensor range covers the most widely used sensing technologies for Arduino, Raspberry Pi, ESP32, and industrial IoT applications. Our Sensors collection includes: Light Sensors — 12mm LDR (Light Dependent Resistor) photoresistors for ambient light detection, automatic brightness control, and light-activated switching circuits; resistance varies from ~1kΩ in bright light to ~10MΩ in darkness Magnetic Field Sensors — linear and analog Hall effect sensor modules for contactless position detection, RPM measurement, current sensing, and magnetic field mapping; compatible with 3.3V and 5V microcontrollers Ultrasonic Range Finders — US-100 ultrasonic distance sensor modules with UART and trigger/echo modes for accurate 2cm–4.5m distance measurement in robotics, obstacle avoidance, and level sensing applications All sensor modules feature pre-soldered headers and onboard signal conditioning for direct connection to microcontroller GPIO pins. Compatible with Arduino, Raspberry Pi, ESP8266, ESP32, and STM32 platforms.
