GUVA-S12SD UV sensor sketch required

[Tommas]

Dear All!

Does anybody have mysensors compatible GUVA-S12SD UV sensor sketch?
I would like to operate it from 3.3V battery connected to Sensebender MIcro.

Thank you in advance!

Hello,

if you're new to MySensors:

• you can use the light sensor example, change the calculation for your sensor, and also change the msg type to UV. https://www.mysensors.org/build/light-lm393
• or use and change directly the UV example https://www.mysensors.org/build/uv

According to adafruit, your calc should look something like that:
UVindex = (ADC reading * Sensor_VCC / 102.4) where Sensor_VCC in your case would be 3.3V. You might need to adapt for a variable voltage as it will follow the battery voltage.

In case you have trouble, post your sketch.
