PCB of the Day! Adafruit AMG8833 IR Thermal Camera Breakout - STEMMA QT 🔥📸🔌

Add heat-vision to your project with an Adafruit AMG8833 Grid-EYE Breakout! This sensor from Panasonic is an 8x8 array of IR thermal sensors. When connected to your microcontroller (or raspberry Pi) it will return an array of 64 individual infrared temperature readings over I2C. It's like those fancy thermal cameras, but compact and simple enough for easy integration.

PCB of the day! Add oodles of analog inputs with an 8-channel ADC 🔌📊🔧

Many microcontrollers have ADCs these days for reading analog/resistive sensors like potentiometers, thermistors, LDR light sensors, etc., but sometimes you need MOAR! or maybe you're using a single board computer like a Raspberry Pi that has no ADCs at all…the ADS7830 is an affordable 8-channel ADC with I2C interface, so it's easy to include with any platform. There are 2 address pins, so you could have 4 x 8 = 32 total ADC channels with chain-able Stemma QT cables. You can get up to 70 Ksamples per second, but only 8-bits of resolution, so it's suitable for rough sensor measurements. This would be a great way to add a ton of potentiometers to a build, especially if it contained a Raspberry Pi, prototype coming soon!

PCB of the Day! The VCNL4200 has long-ranging vision 🔍🤖🛠️

The VCNL4200 proximity sensor https://www.digikey.com/en/products/detail/vishay-semiconductor-opto-division/VCNL4200/7394601 , which we found on last weeks The Great Search ---

youtube

can detect motion up to 1.5 meters away, and has an I2C interface that makes it an excellent match for a Stemma QT board prototype. Which is what we've got here! Note the IR LED requires an external P FET to drive it!

Great Search part turns into an ultra-precision temp+RH sensor 🌡️🔍💧

A few weeks ago we were looking at the latest in temperature and humidity sensors on The Great Search (https://blog.adafruit.com/2024/03/04/the-great-search-high-accuracy-temperature-humidity-sensor-thegreatsearch-digikey-digikey-adafruit/) and we chanced across the HDC3020 series (https://www.digikey.com/en/products/detail/texas-instruments/HDC3020DEFR/17884961) of 'ultra accurate' humidity sensors, with 0.5% accuracy in most cases. this seems like a nice addition to our collection of environmental sensors so we spun out a quick QT sensor (https://www.adafruit.com/stemma) for plug-n-play usage. the HDC can use 2-5V power and logic so no level shifting required! and you can select up to 4 I2C addresses, using jumpers on the back.

Prototype build time lapse! Adafruit ENS160 MOX Gas Sensor - Sciosense CCS811 Upgrade - STEMMA QT / Qwiic 🛠️🌬️📈

The ENS160 Gas Sensor is an excellent air quality sensor from ScioSense, replacing the discontinued CCS811, with new driver code. This sensor incorporates a microcontroller and MOX sensor to provide detailed air quality readings via an I2C interface, but calibration against known sources is required for precision. The sensor, on a custom PCB in the STEMMA QT form factor for easy interfacing, allows for humidity and temperature compensation and supports both 3.3V and 5V systems.

In stock and shipping now.
