Category: Sensors

The TSL2561 (HCARDU0102) Luminosity sensor module is a light to digital interface module. The sensor contains two photodiodes, one which can detect visible light and infrared (IR), and a second which can detect IR light. Two integrating analog-to-digital converters (ADC) integrate currents from the two photodiodes to produce a digital representation of the the light intensity hitting the sensor.

Henry E. ★★★★★

The breakout pins are spaced perfectly for a breadboard, so I had it reading ambient light levels within minutes of soldering. It's accurate enough to notice the difference between a cloudy day and a shaded corner, which is exactly what I needed for my project.

Edward ★★★★★

The dual photodiodes are the real deal—it picks up both visible and IR light cleanly, which made my daylight logging project way more accurate than I expected. Hooked it up over I2C and had raw lux readings within minutes.

Victoria N. ★★★★★

Finally got this sensor working in my automated greenhouse setup to monitor ambient light levels. The dual photodiode design picks up both visible and infrared light separately, which gives me much more accurate readings than my old analog sensor. Calibration was straightforward with the I2C library
