# QRE1113 Reference Design ## Description This project is a QRE1113 opto-reflective sensor circuit, using a 47K pull-up resistor (R2) and a 100 Ohm resistor (R1). It includes a 1µF capacitor (C1) for stability and attaches to a JST connector (J1) for easy interfacing. Power is provided via VCC, with the output signal (OPTO_OUT) fed back. #referenceDesign #industrialsensing #onsemi #template #reference-design ## Project Details - **Owner:** vasyl - **Created:** 11/21/2023 - **Last Updated:** 2/8/2024 - **Visibility:** Public - **License:** https://creativecommons.org/licenses/by/4.0/ - **Copies:** 2 ## Key Components ### IC1 — [QRE1113GR](https://www.flux.ai/vasyl/qre1113gr~tts.md) - Datasheet URL: https://www.onsemi.com/pdf/datasheet/qre1113-d.pdf - License: https://creativecommons.org/licenses/by/4.0/ - Manufacturer Name: onsemi - Manufacturer Part Number: QRE1113GR - Part Type: Reflective - Analog Output **Pins:** - ~ [pin 1] - ~ [pin 4] - ~ [pin 3] - ~ [pin 2] ### J1 — [QWIIC I2C JST Connector](https://www.flux.ai/vasy_skral/qwiic-i2c-jst-connector~d55.md) - Datasheet URL: https://media.digikey.com/pdf/Data%20Sheets/JST%20PDFs/SR%20Connector.pdf - Manufacturer Part Number: SM04B-SRSS-TB - Part Type: Connector - Manufacturer Name: JST Sales America Inc. **Pins:** - 1 [pin 1] - 2 [pin 2] - 3 [pin 3] - 4 [pin 4] *The full schematic, PCB layout, bill of materials, and interactive design are available at [https://www.flux.ai/vasyl/qre1113-reference-design~u23](https://www.flux.ai/vasyl/qre1113-reference-design~u23).* --- *Generated from [https://www.flux.ai/vasyl/qre1113-reference-design~u23](https://www.flux.ai/vasyl/qre1113-reference-design~u23)*
