Halloween Sensors

AF-161

CdS cells are little light sensors. As the squiggly face is exposed to more light, the resistance goes down. When its light, the resistance is about 5-10KΩ, when dark it goes up to 200KΩ.

AF-1375

This breakout board is the simplest way to create a project with a single "toggle" capacitive touch sensor.

AF-182

This sensor can detect flexing or bending in one direction. They were popularized by being used in the Nintendo PowerGlove as a gaming interface.

AF-419

Punch in your secret key into this numeric matrix keypad. This keypad has 12 buttons, arranged in a telephone-line 3x4 grid. It's made of a thin, flexible membrane material with an adhesive backing (just remove the paper) so you can attach it to nearly anything. The keys are c...

AF-158

Hall effect sensors detect whether a magnet is near. Useful for non-contact/waterproof type switches, position sensors, rotary/shaft encoders. I tried dozens of different hall effect sensors to see which one would work best for the SpokePOV kit (to determine the wheel location...

AF-1374

This breakout board is the simplest way to create a project with a single "momentary" capacitive touch sensor.

AF-984

The HRLV-MaxSonar-EZ sensor line is the most cost-effective solution for applications where precision range-finding, low-voltage operation, space saving, and low-cost are needed.

AF-3316

The VL6180X (sometimes called the VL6180) is a Time of Flight distance sensor like no other you've used! The sensor contains a very tiny laser source, and a matching sensor. The VL6180X can detect the "time of flight", or how long the laser light has taken to bounce back to th...

AF-1767

The "poor man's" accelerometer/motion sensor! These spring-vibration switches are low sensitivity non-directional vibration induced trigger switches. Inside is a stiff spring coiled around a long metal pin. When the switch is moved, the spring touches the center pole to make c...

AF-176

An assortment of the most common sensors used in electronics. 9 sensors and 3 additional components to interface with the 'analog world'. We have some tutorials here, to get you started.

AF-1766

The "poor man's" accelerometer/motion sensor! These spring-vibration switches are high sensitivity non-directional vibration induced trigger switches. Inside is a very soft spring coiled around a long metal pin. When the switch is moved, the spring touches the center pole to m...

AF-173

The "poor man's" accelerometer! Tilt sensors are switches that can detect basic motion/orientation. The metal tube has a little metal ball that rolls around in it, when its tilted upright, the ball rolls onto the contacts sticking out of end and shorts them together.

AF-160

Piezo buzzers are used for making beeps, tones and alerts. This one is petite but loud! Drive it with 3-30V peak-to-peak square wave. To use, connect one pin to ground (either one) and the other pin to a square wave out from a timer or microcontroller. For the loudest tones, s...

AF-1748

This cyber-tronic looking sensor hides a secret behind its glimmering eye. Unlike most temperature sensors, this sensor measures infrared light bouncing off of remote objects so it can sense temperature without having to touch them physically. Simply point the sensor towards w...

AF-1386

This tiny little camera module can be a pretty neat project addition, it is just like our other JPEG cameras (same chipset/software), but much smaller and slimmer.

AF-1075

FSRs are sensors that allow you to detect physical pressure, squeezing and weight.

AF-1071

FSRs are sensors that allow you to detect physical pressure, squeezing and weight.

AF-1070

AF-1602

Add lots of touch sensors to your next microcontroller project with this easy-to-use 8-channel capacitive touch sensor breakout board, starring the CAP1188. This chip can handle up to 8 individual touch pads, and has a very nice feature that makes it stand out for us: it will ...

AF-466

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 ...

AF-1333

This membrane keypad has a single key, but it does have an embedded surface-mount red LED installed.

AF-1332

Punch in your secret key into this numeric membrane keypad.

AF-1031

This SHARP distance sensor bounces IR off objects to determine how far away they are.

AF-1917

The Sensor Film Kit is a great new way to make custom-sized sensors out of force sensitive material. This kit includes one piece of black plastic sensor film (it's thicker and more durable than Velostat but similar in function), two pieces of heavy aluminum foil, and two piece...

AF-983

The HRLV-MaxSonar-EZ sensor line is the most cost-effective solution for applications where precision range-finding, low-voltage operation, space saving, and low-cost are needed.

AF-982

LV-EZ4 Maxbotix Ultrasonic Rangefinder provides very short to long-range detection and ranging, in an incredibly small package.

AF-1568

This extra-long-range SHARP distance sensor bounces IR off objects to determine how far away they are.

AF-981

LV-EZ3 Maxbotix Ultrasonic Rangefinder provides very short to long-range detection and ranging, in an incredibly small package.

AF-980

LV-EZ2 Maxbotix Ultrasonic Rangefinder provides very short to long-range detection and ranging, in an incredibly small package.

AF-979

LV-EZ0 Maxbotix Ultrasonic Rangefinder provides very short to long-range detection and ranging, in an incredibly small package.
