Overview
Product Description
The IR Range Sense is a self-build DIY electronics kit that includes everything needed to either detect the range of a surface, or the presence of a nearby object. Powered from voltages between 3V and 12V, the IR Range Sense has two outputs; one digital and one analogue.
The digital output is connected to the output of the onboard comparator that produces either a logical 1 or 0 depending on the presence of IR light, and the IR Range Sense potentiometer is used to determine the sensitivity of the switch. The analogue output is a voltage that is proportional to the amount of IR light falling onto the IR sensor, and this can be useful for measuring distances, or for determining if an object has crossed in front of the sensor.
While the board comes with components suitable for most applications, it is perfectly possible to change the components to adjust its operation. For example, changing the size of the IR series resistor can increase the sensitivity of the IR sensor.

Applications
- The IR Range Sense is an excellent kit for those needing to determine a surface’s range or to detect an object’s presence in front of the kit. In addition to ranging, the kit can also be used to determine the presence of a reflective surface, which is commonly used in line-following robots. The IR Range Sense is also excellent for those needing to count passing objects or determine if a container is full or empty (these devices are commonly found in industrial sites that rely on automation). For applications that need to detect another IR source, it is better to use the IR Sense kit as this eliminates the onboard IR LED.
- Education and training – Useful for teaching infrared emitters and sensors, reflective sensing and analogue sensor outputs, while providing practical experience with through-hole soldering, component identification and PCB assembly.
- Project integration – Suitable for projects such as Proximity Detector, IR Barrier, Fine Position Detector, and other designs where the following function is useful: Reflective infrared sensing module with analogue and digital outputs for proximity and object detection

Notes
- Electrical specifications are nominal and may vary with component tolerances, supply voltage, load and operating conditions.
- The product is supplied in kit form and requires soldering and assembly before use.
- Check component values and observe the polarity or orientation of ICs, diodes, LEDs, transistors and electrolytic capacitors before applying power.
- Sensor thresholds and analogue readings can vary between components and environments; calibrate the module for the intended application.
