Two-way infrared obstacle-detection module for Arduino-compatible robots, line-following experiments and automation prototypes. Its reflective IR sensing can be adjusted for the application, but reliable range depends on target colour, surface texture, angle and ambient light. Calibrate both sensing paths in the final installation environment.

The two-way infrared obstacle sensor is a reflective detection module for mobile robots, obstacle-avoidance experiments and basic automation. It emits infrared light and monitors the reflected signal from a nearby object, providing controller-friendly detection outputs without physical contact.
Detection strength changes with the amount of infrared light reflected back to the receiver. Light-coloured, smooth targets may be detected more easily than dark, angled or absorbent surfaces. Strong sunlight and other infrared sources can also affect performance, so the module should be adjusted and tested in the actual operating environment.
This module is suitable for short-range presence and obstacle detection, but it is not a calibrated distance-measurement sensor. Use an ultrasonic or time-of-flight sensor when numerical distance readings are required.
For compatible controller testing, connect the module to an Arduino UNO R3 only after confirming the sensor supply voltage and output logic.

It emits infrared light and monitors the reflected signal. A nearby surface changes the received reflection and the module produces a detection output.
Yes. Strong light, surface colour, texture, angle and reflectivity can change the reliable detection distance, so calibrate the module in its actual environment.
Yes. Connect the supported supply and ground, then read the module outputs with compatible Arduino digital input pins.
No. It detects changes in reflected infrared light and is not a calibrated distance sensor. Use an ultrasonic or time-of-flight sensor when numerical distance readings are required.
It is suitable for short-range obstacle detection in mobile robots, Arduino-compatible experiments and basic automation, provided both sensing paths are calibrated in the final environment.
ACS712 Current Sensor 30A current sensor board is based on the Allegro ACS712ELCTR-30A bi-directional hall-effect current sensor chip that detects positive and negative flowing currents in the range of minus 30 Amps to positive 30 Amps. The board operates at 5V DC and the current flow through the sensor is converted to an output voltage starting at 1/2Vcc (or 2.5V) for no current flow and moves up 66mV per amp for positive current or down -66mV per amp for negative current.
2.2-inch resistive flex sensor for measuring relative bend in Arduino-compatible wearables, robotics, controls and motion experiments. Resistance increases as the active strip bends. Secure the base, use a voltage-divider circuit and avoid creasing or repeatedly flexing the connector area.
Multi-sensor 10 DOF IMU module for acceleration, rotation, magnetic-field and barometric-pressure measurements in robotics and navigation prototypes. Board revisions may use different sensor IC combinations, so verify the supplied board markings, I2C addresses and library compatibility before setup.
HC-SR501 passive infrared motion sensor for Arduino-compatible alarms, automatic lighting and occupancy prototypes. It provides adjustable sensitivity and output delay, plus repeatable or non-repeatable trigger modes. Allow a warm-up period and test the installed detection area before relying on the output.
