GUVA-S12SD UV Detection Sensor arduino controller The module has four holes

The module has four holes 3mm (M3) holes for mounting

Flash Memory: 32 KB of which 2 KB used by bootloader

It can also be used for macro photography because it can focus on objects at very short distances

Ambient temperature: -25 degrees Celsius to +70 degrees Celsius

but works quite well from 2KHz to 10KHz
