Shop Light, Optical & Proximity Sensors by Type

Our light, optical and proximity sensor range may include modules such as:

• Light Sensor Modules: LDR and photoresistor modules for detecting ambient light levels in Arduino, ESP32 and electronics projects.
• IR Sensor Modules: Infrared transmitter and receiver modules for object detection, reflection sensing and proximity applications.
• Reflective Optical Sensors: Modules used for line tracking, object detection, wheel encoders and reflective surface sensing.
• Obstacle Avoidance Sensors: Sensors commonly used in small robotics projects to detect nearby objects or surfaces.
• Proximity Sensor Modules: Modules used to detect the presence or distance of nearby objects in compatible low-voltage electronics projects.

Optical Sensors for Arduino, ESP32 & Robotics Projects

Light and optical sensors are commonly used in robotics, automation, counters, object detection, line following, smart lighting, light meters, alarm projects and sensor-based control systems. Many modules provide analog output, digital output or adjustable threshold outputs depending on the board design.

These modules are commonly used with Arduino compatible boards, ESP32, ESP8266, Raspberry Pi compatible boards, STM32 and other microcontroller platforms. Always check the supply voltage, output type, sensing range, detection angle, sensitivity adjustment and mounting requirements before ordering.

Light Sensors, IR Sensors, Line Tracking & Obstacle Detection

Different optical sensors suit different applications. LDR modules are useful for detecting light and dark conditions. IR reflective sensors are useful for line tracking, object detection and surface sensing. Obstacle detection modules are commonly used in robotics and simple automation projects.

If your project needs distance measurement rather than simple proximity or reflection sensing, check whether an ultrasonic, infrared or time-of-flight sensor is more suitable for the required range and accuracy.

Frequently Asked Questions

Do you sell light sensors for Arduino and ESP32?

Yes. AuscomTech stocks light, optical and proximity sensor modules suitable for Arduino compatible boards, ESP32, ESP8266 and general electronics projects.

What is an LDR light sensor used for?

An LDR or photoresistor sensor is commonly used to detect changes in ambient light, such as day/night detection, light-activated switching and simple brightness measurement projects.

What are IR sensor modules used for?

IR sensor modules can be used for object detection, line tracking, proximity sensing, reflective surface detection and robotics projects depending on the module design.

What is the difference between a proximity sensor and a distance sensor?

A proximity sensor usually detects whether an object is nearby, while a distance sensor is designed to measure distance more directly. Check each product’s sensing range and output type before choosing a module.

Can you help me choose the right optical sensor?

Yes. If you are unsure which sensor suits your project, contact AuscomTech with details of what you need to detect, your controller board, voltage, required sensing range and environment.
