Description

The Sharp Microelectronics GP2S700HCP is a high-precision reflective photointerrupter module integrating an infrared LED emitter and a phototransistor detector within a single, epoxy-molded surface-mount device (SMD). Its fundamental sensing principle relies on detecting the reflection of its 950nm infrared beam from a target object, with the analog output of the phototransistor varying proportionally to the reflected intensity. This allows for reliable detection of objects within a calibrated range of 0.2mm to 5mm.

Engineered for stability and durability, the module incorporates a visible light cut resin that filters out ambient light interference, ensuring consistent detection accuracy. Its leadless package is fully compatible with standard reflow soldering processes, facilitating efficient PCB assembly. The device is specified for operation across a broad industrial temperature range from -30°C to +75°C and is RoHS compliant, meeting modern environmental and manufacturing standards for automated production environments.

Frequently Asked Questions

What is the optimal sensing distance for the GP2S700HCP?

The Sharp Microelectronics GP2S700HCP is designed with an optimal sensing distance of approximately 3mm, where the reflected signal strength is greatest for reliable detection. The sensor's effective operational range extends from 0.2mm to 5mm, but for the most stable and repeatable analog output reading, positioning the target at the 3mm point is recommended.

Is this sensor compatible with 3.3V microcontroller systems like ESP32 or Raspberry Pi?

Yes, the GP2S700HCP operates on a supply voltage range of 3.3V to 5V DC, making it directly compatible with 3.3V logic microcontrollers such as ESP32, STM32, and Raspberry Pi GPIO. The analog phototransistor output can be connected directly to an ADC input pin on these controllers for distance or presence measurement.

How does the 'visible light cut resin' improve sensor performance?

The integrated visible light cut resin acts as an optical filter over the phototransistor, selectively blocking ambient light in the visible spectrum while allowing the sensor's own 950nm infrared light to pass. This significantly reduces false triggers and signal noise caused by changing room lighting or sunlight, ensuring higher detection accuracy and stability in varying environmental conditions.

Can I use this sensor for detecting transparent or glossy objects?

Detection of transparent or highly reflective (glossy) objects can be challenging and may require specific calibration. Transparent materials may not reflect enough infrared light, while glossy surfaces can cause specular reflection away from the detector. For reliable operation, testing with the actual target material at the intended distance is necessary to confirm signal strength meets your application's threshold.
