CJMCU-101 OPT101 Analog Light Intensity Module

Monolithic Photodiode & Op-Amp Integration: Combines an optical photodiode and an on-chip transimpedance amplifier on a single IC chip to generate clean, low-noise analog voltage outputs.

Linear Voltage Output Telemetry: Delivers an analog voltage signal directly proportional to light intensity, simplifying optical measurements on microcontroller ADC pins.

Broad Wavelength Spectral Response: Operates across a wide spectral range (300 nm - 1000 nm) with peak sensitivity in the near-infrared region (650 nm), making it ideal for visible light and IR telemetry.

Wide Supply Voltage Range: Operates reliably across 2.7V - 36V single or dual power supplies, supporting easy integration with 3.3V, 5V, and higher industrial control rails.

Compact CJMCU Breakout Form Factor: Features a streamlined PCB layout with standard pin headers for easy breadboard prototyping and custom optical setup mounting.

Housing & Board Material: Durable FR-4 glass-epoxy PCB with gold/tin-plated contact pads and a surface-mounted or DIP-packaged OPT101 photodiode IC.

Technical Specifications:

Operating Voltage: 2.7V - 36V DC.

Peak Sensitivity Wavelength: 650 nm (Sensitivity Range: 300 nm - 1000 nm).

Output Signal: Linear Analog Voltage.

Color: Purple PCB with Gold Contact Terminals and Clear IC Package.

Usage Advice: Connect VCC (2.7V-36V), GND, and OUT to an analog ADC input pin on your microcontroller; align the optical window directly toward the target light source.

Maintenance: Keep the clear optical IC surface clean and free of dust, grease, or solder flux; gently wipe with an isopropyl alcohol swab or dry microfiber cloth when necessary.

Essential High-Precision Optical Transducer: Position as a precision monolithic photodiode module for medical instrumentation, laboratory light measurements, smoke detectors, and optical pulse analytics.

Highlight Monolithic Low-Noise Architecture: Emphasize how integrating the photodiode and amplifier on the same silicon die eliminates external noise coupling, stray capacitance, and leakage currents typical of discrete photodiode circuits.

Recommended Cross-Sell Add-ons: Pair with OPT3001 Ambient Light Sensor, TEMT6000 Light Sensor Module, Photo transistor 3DU33, and ESD antistatic mat 50x40CM PCB Welding Mat.
