#i2cinterface

We stock and use a couple of different I2C ADCs, such as the NAU7802

and the HX711

Both of these are kinda designed specifically for load cells. This is a more general-purpose 24-bit ADC using the ADS122C04

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 🔍🤖🛠️

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.
