Great for plant monitoring systems

I use this to monitor sunlight exposure for my automated greenhouse. The dual-channel detection helps me understand the specific light spectrum plants are receiving.

Reliable UV tracking

Integrated this into a custom hiking watch prototype. It handles temperature variations well and the power consumption is low enough for battery-operated devices.

Perfect for my weather station project

This sensor integrates easily with Arduino and ESP32 boards. The I2C communication is stable, and the readings for both UVA and UVB seem accurate when compared to my handheld meter.

Solid performance, clear datasheet

The documentation provided by the manufacturer was very helpful. The sensor responds quickly to changes in light conditions. Only minor issue was the soldering pads are quite small.

Good sensitivity, small footprint

The size is great for compact wearable designs. It took a little tweaking to get the calibration right in my code, but once set up, it provides consistent data.

Excellent value for money

Bought five of these for a batch of prototypes. All arrived in perfect condition and functioned immediately. Highly recommend for hobbyists and professionals alike.

5 FAQ

Q: Is there an Arduino library available for this?

A: Yes, there are several open-source libraries available on GitHub that support the VEML6075 chip. They handle the I2C register configuration and data conversion for you.

Q: What is the accuracy range for UV Index calculation?

A: While the sensor provides high-resolution raw data, calculating the exact UV Index requires software calibration based on your specific environment. The hardware itself has a linearity error of typically less than 5%.

Q: Can I use this underwater?

A: The sensor component itself is not waterproof. It must be housed in a waterproof enclosure with a UV-transparent window (such as quartz or specific plastics) to function correctly underwater.

Q: Does this module come with a breakout board?

A: This listing is for the raw SMD sensor component only. We do sell a separate breakout board version with pull-up resistors and voltage regulation if you prefer not to solder the SMD part directly.

Q: Is this sensor compatible with 5V logic levels?

A: The sensor operates at 2.5V to 3.6V. If you are using a 5V microcontroller, you will need a logic level shifter or a breakout board with built-in regulation to avoid damaging the component.
