A UV detection sensor module that measures ultraviolet light intensity in the 200–370 nm wavelength range. The analogue output (0–1 V DC) is proportional to the UV Index, making it suitable for measuring UV exposure in sunlight and other UV sources. Compatible with 3.3 V and 5 V microcontrollers.
Key Features
- UV Index Measurement – ±1 UV Index accuracy
- Wide Wavelength Range – 200–370 nm detection
- Analogue Output – 0–1 V DC proportional to UV intensity
- Simple 3-Pin Connection – VCC, GND, and analogue signal output
Wiring
- VCC – Power input (3.3–5 V)
- GND – Ground
- OUT – Analogue signal output (connect to MCU analogue input)
Specifications
- Working Voltage: 3.3–5 V
- Output Voltage: 0–1 V DC
- Measuring Accuracy: ±1 UV Index
- Wavelength: 200–370 nm
- Operating Temperature: −20 to 85 °C
- Dimensions: 19.8 × 15 mm
Package Contents
- 1× UV detection sensor module
Jargon buster
Plain-language definitions for the technical terms used above.
- DC
- DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
- GND
- GND is the ground or reference connection (0 V) for a circuit. When connecting two devices together, their grounds must be joined so both agree on what counts as a low or high signal.
- Torque
- A twisting force that causes something to rotate, usually measured in newton-metres or kilogram-centimetres. It matters when choosing motors, servos, gears, and tools because higher torque is needed to lift heavier loads, turn larger wheels, or move mechanisms without stalling.
- VCC
- VCC is the positive power-supply connection on a chip or module. Connecting it to the correct supply voltage is needed for the part to power on and helps avoid damaging the electronics.
- wavelength
- The distance between repeating peaks of a wave, often used to describe the colour of light in nanometres. For visible lasers and LEDs, wavelength tells you the approximate colour, such as red, green or blue.
