Breathe easy, knowing that you can track and sense the quality of the air around you with this Adafruit PMSA003I Air Quality Breakout. This sensor is great for monitoring air quality, in a compact plug-in format. Best of all, unlike almost all other sensors we've seen that are UART interface, this one is I2C interface, which makes it a great match for single-board...

*sniff* *sniff* ... do you smell that? No need to stick your nose into a carton of milk anymore, you can build a digital nose with the SGP40 Multi-Pixel Gas Sensor, a fully integrated MOX gas sensor. This is a very fine air quality sensor from the sensor experts at Sensirion, with I2C interfacing so you don't have to manage the heater and analog reading of a MOX...

Pulse Sensor Amped is a greatly improved version of the original Pulse Sensor, a plug-and-play heart-rate sensor for Arduino and Arduino compatibles. It can be used by students, artists, athletes, makers, and game & mobile developers who want to easily incorporate live heart-rate data into their projects. Pulse Sensor Amped adds amplification and noise...

Breathe easy, knowing that you can track and sense the quality of the air around you with the PM2.5 Air Quality Sensor with Breadboard Adapter particulate sensor. Mad Max & Furiosa definitely should have hooked up one of these in their truck while scavenging the dusty desert wilderness of post-apocalyptic Australia. And for those of us not living in an Outback...

This thin silvery ribbon is an interesting sensor. It's made of 2mm wide by 600mm long piezoelectric film sandwich. Piezo film can be used to detect motion or vibration - when shifted around or touched, it creates a small current pulse across the terminals. If a 1 Mega-ohm resistor is placed across the two terminals you will see the current converted into a voltage...

Control your next project with your muscles with the MyoWare 2.0 Muscle Sensor! Pair the MyoWare with some Muscle Sensor Surface EMG Electrodes and a microcontroller (ie. Raspberry Pi, Arduino, or Beagle Bone Black) to create a DIY low-cost version of an EMG or an electromyograph! Electromyography is an electrodiagnostic medicine technique for evaluating and...

Secure your project with biometrics - this all-in-one optical fingerprint sensor will make adding fingerprint detection and verification super simple. It's easy to use and more affordable than ever! These modules are typically used in safes - there's a high powered DSP chip that does the image rendering, calculation, feature-finding, and searching. Connect to any...

Secure your project with biometrics - this all-in-one optical fingerprint sensor will make adding fingerprint detection and verification super simple. It even has an LED ring built around the detection pad, which can be set to red, blue or purple (as well as some fading/blinking effects) for a great user experience. These modules are typically used in safes - there's...

Have your next project be controlled by your muscles with this pack of Muscle Sensor Surface EMG Electrodes! Pair the electrodes with the MyoWare Muscle Sensor and a microcontroller (ie. Arduino, or anything else with analog input reading ability) to create a DIY low-cost version of an EMG or an electromyograph! This is for hobbyist use only. Electromyography is an...

Secure your project with biometrics - this adorably tiny, all-in-one, optical fingerprint sensor will make adding fingerprint detection and verification super simple. It's extremely slim, with a plastic casing that can be glued or panel mounted into any enclosure! There are some embedded blue LEDs that light up the outer casing when the sensor is waiting for finger...

These modules are typically used in safes - there's a high powered DSP chip that does the image rendering, calculation, feature-finding and searching. Connect to any microcontroller or system with TTL serial, and send...

Discontinued - you can grab this Pulse Sensor Amped instead! Read wireless heart-rate data into your electronics projects in under 10 minutes with this educational experimentation kit for Polar wireless heart rate bands. This pack is designed for students, hobbyists, engineers, and artists who want to add biometric interactivity to electronics. This is the easiest...

This simple dust sensor is a great way to add basic particulate sensing to your next project. It's not as fully featured as our PM2.5 I2C/UART-based sensors, with just a single analog voltage output. However, for the price, it can't be beat! The SHARP GP2Y1014AU0F Dust Sensor Module Kit particulate sensor uses an LED to bounce off of particles suspended in the air -...
