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 induces current to flow from the long pin to the short pin. This sensor has a built-in optical filter (probably IR filter) so it'll do a fair job of simulating light levels as the human eye does. To use,...

This is the BH1750 16-bit Ambient Light Sensor from Rohm. Because of how important it is to humans and most other living things, sensing the amount of light in an environment is a common place to get started when learning to work with microcontrollers and sensors. Should we turn up the brightness of our display or dim it to save power? Which direction should your...

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 most of UVA spectrum). The signal level from the photodiode is very small, in the nano-ampere level, so we tossed on an opamp to amplify the signal to a more manageable volt-level. This sensor is much...

The VCNL4010 sensor is a nice way to add a small-distance proximity sensor to your microcontroller project. For longer distances (in the range of cm, you can use a SHARP IR distance sensor, but those are only good if the object is over 10 cm away. The VCNL4010 is designed for much shorter distances, no more than 200mm (about 7.5") and under our experimentation we...

Ever wanted your microcontroller to sense images without eating up all your processor speed? Or wish that you had an image sensor that wasn't limited to RGB - but could sense hue and saturation as well? Or just want a kickstarted, open source camera sensor with a cool name? Enter the Pixy2 CMUCam5 - an image sensor for your microcontroller that you can teach what to...

Vishay has a lot of light sensors out there, and this is a nice simple lux sensor that's easy to add to any microcontoller. Most light sensors just give you a number for brighter/darker ambient lighting. The VEML7700 makes your life easier by calculating the lux, which is an SI unit for light. You'll get more consistent readings between multiple sensors because you...

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. Unlike the Si1145, this sensor will not give you UV Index readings. However, the Si1145 does UV Index...

The Adafruit LTR-303 Light Sensor a simple and popular low-cost I2C digital light sensor that is easy to integrate into your project for reliable and wide-ranging light measurements. Perfect for a wide range of project use cases: Should we turn up the brightness of our display or dim it to save power? Which direction should your robot move to stay in an area with the...

The Adafruit LTR-329 Light Sensor a simple and popular low-cost I2C digital light sensor that is easy to integrate into your project for reliable and wide-ranging light measurements. Perfect for a wide range of project use cases: Should we turn up the brightness of our display or dim it to save power? Which direction should your robot move to stay in an area with the...

This breakout is chock full o' sensors! Add basic gesture sensing, RGB color sensing, proximity sensing, or ambient light sensing to your project with the Adafruit APDS9960 Proximity, Light, RGB, and Gesture Sensor. When connected to your microcontroller (running our library code) it can detect simple gestures (left to right, right to left, up to down, down to up are...
