The Pyrotechnic Pyroelectric Detector (PPD) is a low-cost thermal detector using a bias ground loop. While theoretically a pure capacitance (hence, noiseless) detector, the detector exhibits a non-stationary noise contribution due to a latent bias current, series resistor, and amplifier gain. To resolve this issue, current-induced noise spikes are added which essentially move the noises around and make them less noticeable over a wider frequency band. Over the years, the trend of smart homes has emerged and become popular across the globe. These smart homes have different types of smart home devices including flame detectors and automatic door switches, visit detectors, temperature & light controllers, and home security. Recently, in February 2021, Panasonic India launched its Miraie range of products including WiFi fans, smart digital watches, and WiFi controller plugs. Hence, such factors can augment growth of the pyroelectric detector market.
The Pyrotechnic Radiation Detector's main advantage over other types of radiation detectors is its ability to detect a much wider temperature range than its contemporaries. Because the electrical field that makes up electrostatic energy has an orientation that is completely different from that of light waves, the detection of this energy can only be done at a distance greater than about five inches. Although some say that the range is actually six inches, this is only in direct light situations. Overall, the range of the Pyrotechnic Radiation Detector is only about three feet at most. When it comes to geographical impact, Asia Pacific seems to be gaining significant traction in the pyroelectric detector market. This is owing to the presence of major market players across the region such as Nippon Ceramic Co. Ltd., Murata Manufacturing, and more. On contrary, North America is exhibiting promising signs due to rapid growth oil & gas sector in the region.
Another major complaint about the PPD is the low sensitivity at high temperatures. Due to an unknown yet the well-known relationship between surface temperature and surface tension of pyroelectric crystals, the detection of temperatures as low as -500o can be a problem. That being said, major challenges such as lack of skilled laborers can significantly impede growth of the pyroelectric detector market in the near future. Furthermore, rapidly increasing research and development costs could possibly restrict growth of the pyroelectric detector market in the near future.
Despite its great power and range capabilities, the pyroelectric detectors of today have a few limitations. The first limitation relates to the detector's capability of detecting high temperatures. Due to the sensitivity of the electronics, the temperatures that are detected will only be those at or below absolute zero. In the recent past, the adoption of infrared detectors in fire detection, gas analysis, and non-contact temperature measurement applications has increased. Major end-use industries such as oil & gas regularly use infrared detectors for fire detection. Thus, such factors augment growth pyroelectric detector market.
