The module operates within a UV detection wavelength range of 200-370nm and outputs a calibrated analog voltage that varies according to the UV light intensity. This analog output can be read by any microcontroller's analog-to-digital converter (ADC) channel.
Specifications and Features:
- Working Voltage: 3.3V to 5V
- Output Voltage: 0V to 1V (corresponding to 0 to 10 UV Index*)
- Detection Wavelength Range: 200nm to 375nm
- Operating Temperature: -20°C to 85°C
- Measuring Accuracy: ±1 UV Index
- Size: 19.8mm x 15mm
The UV Sensor module uses the GUVA-S12SD photodiode, a Gallium Nitride (GaN) Schottky-type photodiode optimized for photovoltaic mode operation. It also integrates an SGM8521 Op-Amp, a rail-to-rail input/output voltage feedback amplifier featuring:
- Wide input common-mode voltage range
- Minimum operating supply voltage of 2.1V and maximum recommended supply voltage of 5.5V
- Bandwidth of 150kHz
- Ultra-low current consumption of 4.7µA
The circuit diagram of the UV Sensor Module features the GUVA-S12SD photodiode and the SGM8521 Op-Amp. One key component is the resistor RX, marked as 310 ohms on some modules, while others may use a 10M resistor at that position. Further insights from users are appreciated to clarify the exact choice of this resistor.
This UV Sensor Module offers a versatile and accurate solution for measuring UV radiation intensity, suitable for applications ranging from health and safety to environmental monitoring and beyond.
