Best ambient light sensor in this price range

Switched from a photoresistor setup to this VEML7700 module and the difference is night and day. Digital readings are stable, and the ability to adjust integration time via code is a fantastic feature.

Solid performance, minor pin labeling issue

The sensor works exactly as advertised. My only small complaint is that the silk screen for the SDA and SCL pins was slightly faint on my board, but once identified, it has been rock solid for weeks.

Ideal for plant monitoring

I'm using this to monitor light exposure for my indoor garden. The spectral response matches human vision well, which correlates nicely with what my plants need. Very happy with the purchase.

Perfect for my smart lighting project

This sensor is incredibly accurate. I used it to automate my desk lamp based on room brightness, and the 16-bit resolution makes a huge difference compared to cheaper analog sensors. The I2C library worked flawlessly with my Arduino.

Great for learning IoT

Bought this for a university project. It was easy to set up with Python on a Raspberry Pi. The data is consistent, though I wish it came with a longer cable for remote sensing applications.

High precision and easy to integrate

Great module for professional prototypes. The dynamic range handles both dim indoor lighting and direct sunlight without saturating. Documentation was clear, and soldering the headers was straightforward.

5 FAQ

Q: Is there a library available for ESP32?

A: Yes, there are several open-source libraries available for the ESP32 platform, including the popular Adafruit VEML7700 library, which is compatible with the ESP32 Arduino core.

Q: Does this module come with header pins pre-soldered?

A: No, the module typically comes with unsoldered header pins included in the package, allowing you to choose between straight or right-angle mounting based on your project needs.

Q: How fast can this sensor take readings?

A: The update rate depends on the integration time setting. With the shortest integration time of 25ms, you can get up to 40 readings per second. Longer integration times provide higher precision but slower update rates.

Q: What is the I2C address for this sensor?

A: The default I2C address for the VEML7700 is usually 0x10. Some breakout boards may allow you to change this address by bridging specific solder pads if you need to use multiple sensors on the same bus.

Q: Can this sensor operate at 5V logic levels?

A: The VEML7700 chip operates between 2.4V and 3.6V. However, most breakout boards include a voltage regulator and level shifters, making them safe to connect to 5V microcontrollers like the Arduino Uno. Please check the specific board schematic to confirm.
