EYE on NPI – SEN54 Environmental Sensor Node #EyeOnNPI #DigiKey @DigiKey @adafruit @sensirion

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.

This all-in-one sensor board is going to be a popular environmental sensor from folks who really know environmental sensing! Digi-Key has a whole bunch of the Sensirion SEN54 sensors in stock right now for immediate shipment and with same-day shipping, you can order today and be sensing by tomorrow afternoon!
