OPT3001 Ambient Light Sensor

Human-Eye Spectral Match: Engineered around Texas Instruments' OPT3001 single-chip lux meter IC, featuring 99% IR rejection to precisely mirror human visual response (300 nm - 1000 nm).

Wide Dynamic Range (0.01 lx - 83,865 lx): Onboard full-scale autoranging logic measurement dynamically spans dark environments to full sunlight without manual gain adjustment.

Low-Power I²C Interface: Communicates over a standard two-wire I²C bus with ultra-low power consumption (1.8 µA active mode), perfect for battery-driven IoT sensors.

Flexible Operating Voltage (1.6V - 3.6V): Onboard level-shifting compatibility allows effortless integration with 3.3V and low-voltage microcontrollers like ESP32, STM32, and Raspberry Pi.

Interrupt Driven Measurement: Includes an INT (Interrupt) output pin to notify microcontrollers of light threshold crossings, saving MCU processing cycles.

Housing & Board Material: FR-4 glass-epoxy PCB with gold-plated solder terminals and surface-mounted OPT3001 IC package.

Technical Specifications:

Operating Supply Voltage: 1.6V - 3.6V DC.

Measurement Range: 0.01 lx - 83,865 lx (Lux).

Communication Interface: I^2C Serial Interface.

Color: Purple PCB with Gold-Plated Solder Terminals.

Usage Advice: Connect VCC (1.8V-3.3V), GND, SCL, and SDA to your controller's I²C bus lines; pull up the ADDR pin to ground or VCC to set unique I²C slave addresses.

Maintenance: Keep optical sensor surface free from grease, dust, or fingerprints; clean gently using a soft, dry lint-free cloth.

Essential Human-Centric Light Meter Node: Position as an upgraded digital lux meter for display backlight control, smart home lighting automation, and weather stations requiring true human-eye illuminance accuracy.

Highlight IR Rejection & Precision: Emphasize how superior infrared suppression delivers accurate lux values under incandescent and halogen light sources compared to standard photoresistors or photodiodes.

Recommended Cross-Sell Add-ons: Pair with GY-30 BH1750FVI Digital Light Intensity Illumination Sensor Module, GY-302 BH1750 light intensity module, TEMT6000 Light Sensor Module, and ESD antistatic mat 50x40CM PCB Welding Mat.
