Sometimes when you have too many choices, it’s hard to make a good decision. In fact, there are times when you just want a bag of LEDs, just one of each, that’s all you want. Well too bad, you are getting two of each! The LED Rainbow Pack contains two diffused 5mm PTH LEDs of each color of the rainbow, red, orange, yellow, green, blue, and purple. This is a great way to sample each one and decide what you really need or just to add a whole bunch of color to your next project.

The LTR390 is one of the few low-cost UV sensors available, and it's a pretty nice one! With both ambient light and UVA sensing with a peak spectral response between 300 and 350nm. You can use it for measuring how much sun you can get before needing to covering up.

This Photo Transistor Light Sensor is a simple sensor that detects ambient light. It's kind of the opposite of an LED - when light hits the little chip inside, it...

This UV Sensor with GUVA-S12SD chip is suitable for detecting the UV raditation in sunlight. It can be used in UV Index Monitoring, DIY project, UV-A Lamp Monitoring, Plants growing Environmental monitoring...etc.

Extend your light-sensing spectrum with this analog UV sensor module. It uses a UV photodiode, which can detect the 240-370nm range of light (which covers UVB and...

The Arduino Ultraviolet Radiation Index Meter (240-370 nm) with direct UV index and harm level output supports UART & I2C, ideal for UV monitoring...

This is a small ambient light sensor that acts as an NPN transistor. The more the sensor is exposed to light, the stronger the base bias. Simple to use! Simple breakout board available below.

The SparkFun Mini AS7331 Qwiic Spectral UV Sensor measures UV radiation on three channels: UVA, UVB, and UVC, with high sensitivity and accuracy...

IP67-rated RS485 UV sensor measures 290-390nm UV intensity & index. Modbus-RTU protocol, 5-30V DC. Ideal for environmental, health, & solar monitoring...
