Sunrise LED CO2 Sensor

sunrise co2 sensor

CO2 sensors have been getting more accurate, cost-effective, and smaller since their creation decades ago. Changes in optical path design and improvements in infrared LED light sources have enabled a new generation of small footprint CO2 sensors that combine low power requirements with good speed and accuracy for wireless IoT (Internet of Things) applications that use battery or solar power.

SenseAir AB of Delsbo, Sweden has always stayed ahead of current industry trends and the Senseair Sunrise 1% CO2 Sensor is ahead of its time. The sensor uses a next-generation, low-power infrared LED that only requires 3V power, with peak current less than 125mA during a reading. It is also designed for both indoor and outdoor air quality measurements from 400 to 10,000ppm CO2.

The SE-11 optical path design and coating are an evolution of many years, not just of R&D but customer application experience. SenseAir's patented Platinum Eternal Quality Coating improves on gold as the standard for reflection and durability.

This sensor is 34x20x12mm, or about 2/3 the size of a 9v battery. Because it is solid-state, it uses no moving parts. Combined with an expected life span of greater than 15-years the Senseair Sunrise sensor can be used in a high vibration environment like a hand-held meter or even utilized inside a moving vehicle.

How Good is the SE-11 CO2 Sensor?

So how good is the Senseair Sunrise SE-11 CO2 Sensor?

Let's look at SenseAir's K-30 CO2 sensor, arguably the world standard for high-production CO2 sensors. Our team at CO2Meter decided to create a test, using the latest version of our free GasLab® software, which includes full support for the Sunrise sensor. 

Sunrise and K30 Graph

From the graph, you can instantly see that the Senseair Sunrise SE-11's performance is right on par with the K-30. When combined with the same 15-year lifespan, smaller size, and lower power requirements, we believe that the SE-11 Sunrise will become the next generation standard for OEM CO2 sensing technology.

High-Volume Production

To provide some background, the Senseair Sunrise SE-11 sensor was designed in collaboration with Asahi Kasei Microdevices (AKM), the parent company of SenseAir AB. The AKM Group is a global manufacturer of sensors, semiconductors, and IC products for the consumer market and is a Tier 1 automotive supplier for products including radar, car audio, remote key-less entry, compasses, accelerometers, and power control circuits.

Using AKM’s experience with LEDs, photodiodes, and signal processing allowed SenseAir to bring the Senseair Sunrise to market with a proven IR-LED element and control circuit. At the same time, AKM’s experience with high-volume automated production allows the Sunrise sensor to be produced in large numbers with high quality.
