Advanced passive IR sensing device known as a thermopile array is required to get beyond these sensing constraints. The thermopile array comprises several interconnected IR sensing elements as opposed to the single sensing unit used by typical PIR motion detectors.
The Global Thermopile Infrared Arrays market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
New Infrared Thermopile Array with 120×84 Pixels. Infrared thermopile arrays from Heimann Sensor are the industry standard for thermal imaging and person detection.
Thermopile arrays are low power, low maintenance, and low cost devices because they can be utilised without a shutter or external cooling.The whole spectrum of thermopile arrays, ranging in size from small to medium to big, are available from Heimann Sensor.
Smallest 8×8 arrays, which fit inside a TO-46 housing, can be used, for instance, to measure body temperature without making contact over distances of up to one metre.
Medium-sized arrays with 16×16 and 32×32 thermoelectric elements are well-suited for TO-39 housings and work well for low resolution thermal imaging applications like person detection and counting for intelligent HVAC, burglar alarms, or hot spot detection in domestic applications like stove top monitoring.
The largest sensor to date was an 80×64 array housed in a TO-8 chassis, which was available with a variety of various lenses and had a 120×90 degree ultra-wide field of view and a 12×9 degree long-distance narrow field of view.
Framerates of 30 Hz and higher are possible using this sensor’s 6 pin SPI interface, which provides for quick data transmission.
The most recent innovation is a 120×84 element thermopile array with even better resolution. The lower pixel pitch of this new array, which is now 60 m instead of 90 m, is what makes it so beautiful. As a result, the focal plane measurements for the 80×64 and 120×84 arrays are comparable.
The same TO-8 chassis and 6 pin SPI interface make a drop-in solution to switch from an 80×64 to a 120×84 array possible. If the 80×64 array is already being used, simply swap it out with the 120×84 array to improve resolution while keeping everything else the same.
