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.  Basically, connect the pin connected to the 'thicker'...

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 simpler than our Si1145 breakout, it only does one thing and gives an analog voltage...

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 found it worked best at distances of about 10-150mm. It would be good for say...

Upgrade a project that uses a photocell with the GA1A12S202 analog light sensor. Like a CdS photo-cell, the sensor does not require a microcontroller, the analog voltage output increases with the amount of light shining on the sensor face. This sensor has a lot of improvements that make it better for nearly any project. The biggest improvement over plain photocells is a true log-lin relationship with light levels. Most light sensors have a...

Add a teeny analog light sensor, the  ALS PT19  analog light sensor is a great way to upgrade a project that uses a photocell and needs RoHS compliance. Due to the high rejection ratio of infrared radiation, the spectral response of the ambient light sensor is close to that of human eyes. It's a pretty simple sensor - connect - to ground, + to 2.5V-5.5V or so to power it. Now measure the analog voltage on the OUT pin. That's...

This Reflective IR Sensor is a simple plastic casing with two elements - an IR LED and an IR phototransistor. You can control the IR LED and turn it on to bounce IR off objects to determine their reflectivity. White & light colored stuff will bounce the light, so  you can detect it. Black & dark colored stuff will absorb the IR light so that it isn't detected. Likewise, if something isn't in the way of the sensor, it won't trigger either. ...

Infrared (IR) break-beam sensors are a simple way to detect motion. They work by having an emitter side that sends out a beam of human-invisible IR light, then a receiver across the way which is sensitive to that same light. When something passes between the two, and its not transparent to IR, then the 'beam is broken' and the receiver will let you know. Compared to PIR sensors, breakbeams are faster and allow better control of where you...

Harder, better, faster, stronger!  All the control and customization for your robot project. The Parallax Feedback 360° High Speed Servo has the functionality of a light-duty servo, continuous rotation servo, high-speed servo, and encoder in one convenient package - what a triple threat! Like most continuous rotation servos, this is controlled by a standard 50 Hz pulse-width-modulation signal. But it adds a little extra - a...

As electronics get smaller and smaller, you'll need a hand examining PCBs and this little USB microscope is the perfect tool. Its smaller and lighter than a large optical microscope but packs quite a bit of power in its little body. There's a 5.0 megapixel sensor inside and an optical magnifier that can adjust from 20x (for basic PCB inspection) to 220x (for detailed inspection). Eight white LEDs are angled right onto whatever you're...

Let's be honest - the hardest part about owning a houseplant is not killing it. And the hardest part about not killing your houseplant, at least for us, is remembering to water it. The Chirp! Plant Watering Alarm is a new device from wemakethings that helps extend the life of your plant by reminding you to water it. It's really simple to use. You just stick the inconspicuous black PCB into your plant's soil with a CR2032 battery in...

Take your sonar outside - great for all weather robots! The XL-MaxSonar-WRMA1 ignores smaller targets and only reports the range to target with the largest acoustic return.

It's the perfect introduction to developing Android Things applications on...

This little USB port go-between is like a speed gauge for your USB devices. Instead of hauling out a multimeter and splicing cables, plug this in between for a quick reading on how much current is being drawn from the port. Great for seeing the charge rate of your phone or tablet, checking your battery chargers, or other USB powered projects. There are a few USB power meters out there, The Practical Meter and the USB Spypow. We wanted something...

The HRLV-MaxSonar-EZ sensor line is the fastest way to get precision range-finding into your computer. No microcontroller or adapter required, simply connect any micro B USB cable (not included) into the sensor and install the FTDI drivers to get serial sonar distance data via serial on any computer operating system. The HR-USB-EZ sensor line provides high accuracy and high resolution ultrasonic proximity detection and ranging in air, in a...

The Pololu Zumo robot is an Arduino-controllable tracked robot platform that is less than 10 cm × 10 cm—small enough to qualify for Mini Sumo. It includes two micro metal gearmotors coupled to a pair of silicone tracks, a stainless steel bulldozer-style blade, an array of six infrared reflectance sensors for line following or edge detection, a 3-axis accelerometer / 3-axis magnetometer / 3-axis gyroscope, and a buzzer for simple...

As electronics get smaller and smaller, you'll need a hand examining PCBs and this little USB microscope is the perfect tool. Its smaller and lighter than a large optical microscope but packs quite a bit of power in its little body. There's a high quality 640x480 camera sensor inside and an optical magnifier that can adjust from 5x (for basic PCB inspection) to 200x (for detailed inspection). Eight mini white LEDs are angled right onto...

Raspberry Pi and Pimoroni Piano HAT have found a new musical companion!
