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...

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...

These sensors are very simple to use, no libraries or complex configurations required. Plug this board into any of our 3-pin JST PH cables (we have ones with header ends, alligator clips, etc) Red goes to 3V to 5V DC power, black wire...

This little buck converter based on the MPM3610 is a marvel, taking up to 21V input and providing a 3.3V output with up to 1.2A current. It's great for supplying power to popular 3.3V voltage circuits from a range of battery or power...

This adorable little board will come in very handy whenever you need a good amount of 5V power. It's the size of a linear regulator, but it's actually a mini-booster! Input 2-5VDC on one side, and get 5V at up to 1A supply on the other....

The ST ISM330DHCX is an industrial quality Accelerometer+Gyroscope 6-DOF IMUs (inertial measurement unit). This IMU sensor has 6 degrees of freedom - 3 degrees each of linear acceleration and angular velocity at varying rates within a...

Measuring voltage and adjusting it is what electronics is all about so you won’t get far without friends like the Adafruit PCF8591 Quad 8-bit ADC + 8-bit DAC combo . A nalog to D igital C onverters help by measuring an analog voltage and...

Potentiometers are the perfect tool when you want to change your circuit by turning a knob. Turns out, there are times when you want to adjust your circuit without manually turning a knob, and the DS1841 I2C Logarithmic Resistor from...

If you're looking for the most compact li'l display for a Raspberry Pi (most likely a Pi Zero ) project, this might be just the thing you need! The Adafruit 128x32 PiOLED is your little OLED pal, ready to snap onto any and all Raspberry...
