Description of Waveshare UV Sensor (B) Ultraviolet Sensor Module DC3.3-5V for UV and Ambient Light Intensity Detection with I2C Output for Direct UV Index Value

This is an ultraviolet sensor board which will directly output UV index value via the I2C interface. It is compatible with both 3.3V and 5V levels. Integrates Si1145 chip with embedded ADC, detects not only ultraviolet, but also ambient light intensity. Directly output UV index value via the I2C interface, needs no calculation. Supports interrupt output, programmable upper/lower threshold. Onboard voltage translator, compatible with 3.3V/5V operating voltages

Works well - computer components

Cool little device, works well when connected to battery and VTVM. This allows you to test your sunglasses for UV protection.

Pros
  • Acceptable
Cons
  • Some cons

Revainrating 5 out of 5

Great sensor for your Arduino, easy to connect and use.

Another great sensor for your Arduino project. Easy to connect to your Arduino, VCC, GND and analog output. As with all sensors, the real trick is figuring out what the output means, but there are plenty of resources online to help.

Pros
  • Absolutely amazing!
Cons
  • Something is wrong

Suitable for experimental purposes

Good UV sensor, with 3.7V battery I connected a small digital voltmeter and got a few mV output in room and 1.5V in normal sun, not accurate scientific way to measure but gives a good idea of the sun's UV Index (I multiply the voltage by 4 to get the UV Index)

Pros
  • New to my collection
Cons
  • Almost everything included

Works fine but there is no documentation so I don't do it.

Works well but no documentation so I don't know if the output is linear or how to convert readings to actual UV values for example. The output is low. With a 5V power supply, the maximum readings I got in sunlight were about 1/2V. The supposed variable amplifier doesn't seem to be working. Turning the potentiometer does not affect the readings.

Pros
  • Worth the money
Cons
  • Secret
