In Mid-May, a Heimann Sensor development and product manager is accompanying the successful second Agrarsense field test in Vindeln, Sweden. Various sensor and measurement systems were tested, including infrared cameras with built-in IR array by Heimann Sensor. The primary goals focus on enhancing the forestry operation efficiency, ensure safety, and to minimize fuel consumption and CO2 emissions.

Introduction Non-Dispersive Infrared (NDIR) spectroscopy is a well-established method for precise gas concentration measurement, especially for greenhouse gases such as CO₂. This thermopile-based sensor system combines ruggedness, accuracy and adaptability for use in demanding environments. Designed to meet the toughest industrial conditions, it features high-temperature operation up to 180 °C, hermetically sealed packaging for long-term durability, a separate, dedicated reference channel sensor and integrated temperature reference for thermal compensation. CO₂ Detection with High Selectivity This HTS-HT sensor is available in a configuration specifically tailored for carbon dioxide (CO₂) detection, using a narrow-band IR filter centered around 4.26 µm, the absorption peak of CO₂. This ensures high selectivity and measurement sensitivity, even at low concentrations. Optional Dual-Sensor Design with Dedicated Reference Channel This dual-channel system comprises two physically separate thermopile sensors: the active sensor measures IR radiation after passing through a sample containing CO₂ and the reference sensor serves to track IR source stability and environmental influences. By continuously comparing signals from both sensors, the system achieves drift-compensated, stable readings, even over long operating periods and in fluctuating environments. Integrated Temperature Reference Each sensor includes a built-in temperature reference, allowing for thermal compensation of the thermopile signal. This ensures that changes in ambient or device temperature do not affect the accuracy of the gas concentration reading—a critical feature in applications with wide or rapidly changing thermal profiles. Durability for Harsh Conditions Each sensor includes a built-in temperature reference, allowing for thermal compensation of the thermopile signal. This ensures that changes in ambient or device temperature do not affect the accuracy of the gas concentration reading—a critical feature in applications with wide or rapidly changing thermal profiles. Applications T his dual-sensor system is ideal for emission monitoring in combustion engines or industrial furnaces, exhaust gas analysis where direct sensor exposure to hot gases is required. Further application fields include process control in harsh chemical environments with temperature and humidity extremes as well as high-reliability safety applications, such as gas leak detection in hazardous areas. Benefits at a Glance • Thermopile sensors rated up to 180 °C for direct integration into high-temperature zones • Hermetically sealed design ensures maximum durability and resistance to environmental effects • Long-term signal stability and reduced need for recalibration • Integrated temperature reference for thermal compensation • Independent reference measurement enables real-time correction for source fluctuations and contamination Conclusion This advanced NDIR sensor system is engineered for high-precision CO₂ monitoring in challenging conditions. With two physically separate thermopile sensors, a built-in temperature reference and hermetic protection, it provides reliability and measurement stability - even at extreme temperatures.

The Sensor and Measurement Science International Conference SMSI 2025 will take place this year 6-8 May in Nuremberg and is related to the leading international trade fair Sensor+Test. Our top expert regarding the integration of AI into the infrared imaging of sensor arrays will hold an informative presentation on May 6 at 12.30 pm, D1.4, about the Development of a Computationally Efficient Person Detection Procedure for Low-Resolution Infrared Sensor Arrays. We would be happy to meet you at the SMSI and discuss this forward-thinking topic with you.

Heimann Sensor is glad to announce its participation to the upcoming OASIS9 exhibition on 10 and 11 March 2025 in Tel Aviv. OASIS9 is the ninth in the highly successful series of OASIS (Optical Engineering and Science in Israel) bi-annual conferences. These conferences bring together scientists and engineers from academia, industry and research institutions, who discuss the most recent advances in optics and photonics, both globally and in Israel. Heimann Sensor will be exhibiting at the INET Booth, so do not hesitate to stop by. We will not only show our great spectrum of high-quality infrared arrays starting from HTPA8x8d up to our new flagship HTPA160x120d, but also show real time person detection possibilities with our HTPA 60x40d L1.9 and our beam profiler.

New year, same booth! Our preparations for the Sensor+Test 2025, which will take place 6-8 May in Nuremberg in Southern Germany, are in full swing. We would be happy to see you at our booth 436 in Hall 1 and show you our newest infrared sensor products. You can receive free fair tickets online: Deutsch: https://service.sensor-test.com/sensorticket.php?Fid=50142 English: https://service.sensor-test.com/sensorticket.php?Fid=50142&Spr=en

We are pleased to introduce already two other HowTo videos. These step-by-step clips regarding our USB Application Set and the WiFi Application Shield help our customers to easily get started. Have a look at the videos below.

Our Heimann Sensor team is pleased to share a great success story: One of our innovative sensors has been included into a new thermal imaging camera that is now available at LIDL throughout Germany and internationally. In this way, this kind of product has become affordable to the masses. After a couple days, the cameras were already sold out in the supermarkets. Nevertheless, the camera is still available on the LIDL online shop at https://www.lidl.de/p/parkside-4-v-waermebildkamera-pwbka-4-a1-1024-messpunkte/p100377390 . The heart of this camera is the Heimann Sensor HTPA32x32d array sensor, which enables spatially resolved temperature measurements for professional use as well as everyday use. For example, it is possible to detect heat loss in buildings or to analyze electrical systems. This success is a further proof of the high quality and competitiveness of Heimann Sensor products.

We are pleased to introduce our new webinar series. Starting with a step-by-step guide of our UDP (Ethernet) application set, you will learn how easy it is to get a thermal video recording with our HTPA arrays. Watch out for future webinar clips!

Heimann Sensor is looking forward to participating in the 25th China International Optoelectronic Exhibition, which takes place 11-13 September 2024 in Shenzhen Bao'an International and Exhibition Center. Meet us at booth no. 8E06 - in cooperation with our sales partner Shenzhen Longxiang Technology Co, Ltd.
