Measure CO2 When It Matters

Infineon’s XENSIV™ PAS CO2 now comes in SparkFun Red! We also have two versions of STMicro's STHS34PF80 Human Presence and Motion Sensor.

Hello and welcome back to another Friday Product Post here at SparkFun Electronics! This week, we have a fine new selection of Qwiic sensors for you. We start the week off with the new SparkFun Qwiic Photoacoustic Spectroscopy CO2 Sensor that utilizes Infineons's PASCO2V01 sensor to provide you with highly accurate CO2 data with a combination of narrow-band filtered IR light and audio to measure CO2 molecule concentration. Following that, we have a Standard and Mini-sized version of our new SparkFun Qwiic Human Presence and Motion Sensors featuring STMicro's STHS34PF80. These two small boards are designed to measure an object's precise black-body radiation (as described by Planck's law) and monitor ambient temperature conditions within its 80° field of view. Let's jump in and take a closer look!

Utilize Infineon's photoacoustic spectroscopy gas measurement system!

The SparkFun Photoacoustic Spectroscopy CO2 Sensor features the XENSIV PAS CO2 sensor package from Infineon©, which measures highly accurate CO2 data in direct parts-per-million (ppm) format over I2C, UART, and PWM. The PAS CO2 employs a photoacoustic spectroscopy measurement system that combines narrow-band filtered IR light and a highly sensitive microphone inside the sensing cavity to measure CO2 concentrations from 0 to 32,000ppm with a best accuracy of ±(30ppm + 3%) when reading between 400ppm and 5,000ppm. It also includes a microcontroller that converts the data into direct ppm readout over any of the three communication interfaces.

The SparkFun Qwiic Human Presence and Motion Sensor (available in both Standard and Mini sizes) is built around the STHS34PF80 Low-power, high-sensitivity infrared (IR) sensor for presence and motion detection from STMicroelectronics. This sensor features an infrared motion and presence detection sensor with an operating wavelength between 5µm and 20µm. The STHS34PF80 sensor comprises a matrix of floating vacuum thermal transistors MOS split into two parts, one exposed to IR radiation and the other shielded. The differential reading between the segments allows the sensor to remove self-heating effects. The STHS34PF80 also incorporates algorithms to detect and discriminate between stationary and moving objects. These features enable the sensor to work as a human presence and motion sensor in different applications such as alarm systems, anti-intruder systems, smart lighting, and room occupancy.

$21.95 $10.68

Panasonic's low-profile PIR motion sensors (10.9mm versus standard 14.4mm height offer space savings for constrained designs) consist of a lens to create various detection zones, an optical filter to block non-infrared light, pyroelectric sensing elements, electromagnetic shielding to all circuitry, and an impedance converter to get an electrical signal. This PIR sensor offers digital output across 32 zones at 5m detection distance with 90° x 90° detection area.


That's it for this week. As always, we can't wait to see what you make! Shoot us a tweet @sparkfun, or let us know on Instagram, Facebook or LinkedIn. Please be safe out there, be kind to one another! We'll be back with more new products next week so make sure to check back then. Happy hacking!

Never miss a new product!

    Rob mentioned some software in his video, but today is turning out to be a bit hectic for me. Could we please get a link to that in the text somewhere?

    Wow! It's more than 48 hours since the Dumpster Dive when live, and the "Check Available Stock" is still showing "250+ available"!
