PIR sensors are used to detect motion from pets/humanoids from about 20 feet away (possibly works on zombies, not guaranteed). This one has an adjustable delay before firing (approx 2-4 seconds), adjustable sensitivity and we include a 1 foot (30 cm) cable with a socket so you can easily reposition the sensor or mount it using the two holes on either side. Runs on 5V-12V power (if you need to run it off of 3V you can do that by bypassing the...

This T-Slot Photo Interrupter  is a simple plastic sensor with two elements - an IR LED and an IR photo-transistor, situated across a U-shaped gap. You can control the IR LED and turn it on to transmit IR light across the gap, to the detector on the other side. This makes it perfect for detecting when something is in the slot - when there's something blocking the light, the sensor turns off, when the object goes away, the sensor...

The VL53L0X is a  Time of Flight  distance sensor like no other you've used! The sensor contains a very tiny invisible laser source, and a matching sensor. The VL53L0X can detect the "time of flight", or how long the light has taken to bounce back to the sensor. Since it uses a very narrow light source, it is good for determining distance of only the surface directly in front of it. Unlike sonars that bounce ultrasonic...

We've got many distance sensors, and the TFmini Distance Sensor is a nice addition. This sensor bounces light off objects and returns the distance in centimeters. It's a nice compact plastic package, with UART serial output. Please note that the company calls this a "LiDAR" but it is not a true LIDAR. Instead, its a time-of-flight (ToF) infrared sensor like the VL53L0X. That said, it's easy to use, and since it spits out...

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...

This little sensor looks an  awful lot  like the popular DHT11/DHT22 temperature and humidity sensors, but unlike classic DHT sensors, it has an I2C interface! That's right, you do not need to use a bit-bang timing-specific protocol to talk to the AM2320, it uses plain-old-I2C. Whew, that makes things a little easier, doesn't it? But!  We'll let you know, this sensor is not well documented like our other, fancier I2C...

This is a pre-wired and waterproofed (with heat shrink) version of the DS18B20 sensor. Handy for when you need to measure something far away, or in wet conditions. While the sensor is good up to 125°C the cable is jacketed in PVC so we suggest keeping it under 100°C. Because they are digital, you don't get any signal degradation even over long distances! These 1-wire digital temperature sensors are fairly precise (±0.5°C...

This is a pre-wired and waterproofed version of the DS18B20 sensor made with a PTFE wire cable. Handy for when you need to measure something far away, or in wet conditions. This sensor is a little more expensive than the other waterproof version we have with a PVC cable because this one can be used up to 125°C - the limit of the sensor itself. That said, it's still not recommended for salt-water or corrosive environments since the...

You can snap pictures at 640x480, 320x240 or 160x120 and they're pre-compressed JPEG images which makes them nice and small and easy to store on an SD card. Perfect for a data-logging, security, or...

This weatherproof camera module is a classy upgrade to the basic camera module we already stock in the shop. The main differences is that this one comes in a nice metal case with a mounting hinge, a 1 meter long cable with the TTL & NTSC signals brought out, and it has an automatic IR LED system for night time photos. When the onboard photo-cell detects that it is too dark for the camera to take a photo, it turns on a ring of 12 IR LEDs that...

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...

Laser break beam sensors are usually kind of cumbersome.  They work by detecting an object breaking a laser beam - but you usually have to set up a laser on one end and a sensor on the other.  Unless your sensor is big, it can easily get out of alignment. ...but not this break beam sensor.  It has a light sensor+lens next to the laser to detect the reflected dot when the beam is broken, so it can sense when someone...

Built to last and better than ever. The Series 1 Pro 3D printers from Type A Machines offer durability, modularity and one of the largest build volumes in their class. Featuring a streamlined aluminum and acrylic body, a glass build surface and a precision laser cut CNC folded metal chassis, the Series 1 Pro pushes the envelope in desktop 3D printing by matching a class leading one cubic foot of build volume with...

The Hummingbird Duo Premium Robotics Kit is a spin-off product of Carnegie Mellon's CREATE lab. Hummingbird is designed to enable engineering and robotics activities for ages 12 and up that involve the making of robots, kinetic sculptures, and animatronics built out of a combination of kit parts and crafting materials. This kit of 33 parts requires no soldering and features every kind of motor or sensor you'll need for your...

ArcBotics’ Hexy the Hexapod is a fully articulated hexapod robot kit. Hexy has six legs, 19 servo motors and is powered by Arduino, while maintaining a price 4-10x less expensive than current hexapod robots. It makes complex robotics less costly, easier to learn with the tutorials and documentation, while being radically more fun (and cute!). At the same time its built with completely open source hardware and software, making discovery and...
