This week’s EYE ON NPI (video) is another banger from Sensirion – who has been really rockin’ out with great sensors over the last few years – it’s the SEN54 Environmental Sensor Node, an all-in-one sensor node that combines all of the Sensirion top hits in one.
This sensor looks like your everyday dust sensor – just like the SPS30 particulate sensor, but combines additional sensors inside!
There’s a few models planned for the SEN5X series – today we’re highlighting the SEN54 which has:
(There’s also a SEN55 which will include an addition NOx sensor, but it has not been released yet)
The sensor uses a sub-processor that will act as a single I2C peripheral to receive commands and send sensor data back. It’s a great deal if you want a simple-to-install air quality sensor with all the goodies.
There’s a 3D model available for mechanical installation, and for connectivity you just need a single JST GHR 6 pin cable which has power, and I2C or UART data. Note that the cable is not sold separately so you’ll need to acquire the cable from a separate vendor or pick up the full evaluation kit that comes with a couple cables at additional cost.
The real success story here is the libraries that are pre-written and supported by Sensirion that makes getting started very very fast. We were able to wire up the SEN54 to an ESP32 board and run the BLE demo within a few minutes!
Using the Sensirion MyAmbience app, we could see instant data show up on our iOS or Android device. Over-all a slick and easy experience. We must say that we’re really impressed with how maker-engineer friendly the sensors and firmware development is.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
