A diet high in fruit (and vegetables) can reduce the risk of developing heart disease, cancer, inflammation and diabetes. But the fruit needs to be fresh for a sustainable, healthy diet. Several techniques are being used to detect ripening fruit. One company, smartGAS in Germany, has two different sensors to detect the ethylene (C2H4) that […]

What is the difference between active and passive IR sensors?
Passive infrared (PIR), or pyroelectric PIR sensors as they are also called, detect infrared (heat) radiation in the range of 0.7 µm to 50 µm. The radiated heat can come from humans, animals, machinery and more. Common applications include: alarm systems consumer electronics human body detection automatic switches including automatic lighting A PIR sensor is […]
How do materials impact a sensor’s performance? Pt 1
For harsh environments, materials provide the difference between survival and failure by addressing thermal, chemical and mechanical operating requirements. However, the right materials are also essential to achieve the desired sensor electrical performance, especially in many more demanding, high performance applications. This starts with the sensing element and extends to the packaging. As one of […]

Offering specialized sensors and interfaces, the system provides easy and versatile integration with wide communication protocols support. Sensors for the Exo Sense Pi include: temperature […]
Infrared sensor module meets special requirements of outdoor applications
Vishay Intertechnology, Inc. introduced a new extended temperature “E” option for its TSSP77038 infrared (IR) sensor module in the Heimdall package. Designed to meet the special requirements of outdoor applications, the Vishay Semiconductors TSSP77038ETR has been enhanced with a storage temperature range of -40 °C to +110 °C and an operating temperature range of -30 […]
What is the difference between a thermal IR sensor and a quantum IR sensor?
Infrared radiation (IR) can be detected by thermal IR and quantum IR sensors. A thermal IR sensor uses infrared energy as heat for detection and its sensitivity is independent of wavelengths. Therefore, it can detect objects in the near IR, mid IR, and far IR bands. The non-contact detectors do not require cooling after exposure […]
