This document introduces the features and usage of Waveshare UV sensor module. It can be applied to UV ray detecting system, outdoors UV monitoring device, sterilizing lamp and etc.
The Waveshare 1 UV Sensor module utilizes an SGM8521 boost converter chip and a GUVA sensor to detect UV rays within the 200nm-370nm range. It operates on a voltage of 3.0V-5.5V and provides a TTL level output. The module is designed for applications such as UV detection systems, outdoor monitoring devices, and sterilizing lamps.
| Boost convertor chip | SGM8521 |
|---|---|
| Operating voltage | 3.0V-5.5V |
| Output type | TTL level output |
| Responsive wavelength | 200nm-370nm |
| Dimensions | 21.0mm*13.0mm |
| Fixing hole size | 2.0mm |
The module uses a GUVA sensor which is ideal for detecting the amount of UV ray without a wavelength filter, as it is sensitive only to UV rays.
The wavelengths of 365nm (UV-A) and 320nm (UV-B) are the cut-off thresholds of the GUVA sensor.
Connect the module's AOUT to GPIOA.6, GND to GND, and VCC to 3.3V on the STM32 board.
