Excelitas Technologies Corp. has introduced the DigiPyro PYD 5731 miniature pyroelectric detector, which is the smallest pyroelectric detector available today. The PYD 5731's small size and superior performance make it ideal for sensor applications that require high assembly density, space constraints, and product size, including products integrated in intrusion alarms and smart homes that use analog and digital detectors for indoor/outdoor purposes.
The new PYD 5731 detector integrates a temperature reference element and offers state-of-the-art 1,8-3,6 V low voltage performance. It has excellent shielding performance and can also communicate with the host microprocessor through a single-wire "direct link" interface for 2x14 bit digital output. Although standard pyroelectric detectors are usually installed in a TO-5 metal package, the new PYD 5731 features a TO-46 package that is only 5.5 mm in diameter. Combined with a digital output and metal shielding package, the DigiPyro series of digital pyroelectric detectors provides outstanding resistance to electromagnetic interference, in addition to the high radiation sensing sensitivity that has been widely recognized in the industry.
"Our DigiPyro digital pyroelectric detectors are designed with the most compact form factor to provide high-performance mobility detection, human-sensing monitoring and remote temperature measurement," said Fred Plotz, Infrared Sensing Manager at Excelitas. "With advanced sensor intelligence, high sensitivity, and easy connectivity, DigiPyro digital pyroelectric detectors have accelerated the smart home and smart city markets, while offering a variety of features that improve the human-computer interface in today's smart products. "This new DigiPyro digital pyroelectric detector, the smallest in size, drives the miniaturization and development of sensor-related smart products for space compact applications."
DigiPyro digital pyroelectric detectors can be used to activate smart home, smart city systems to monitor and adjust temperature in HVAC, light switch control, activate security cameras and anti-theft system functions, and increase the intelligence and autonomy of home appliances. They can also be used in gas and smoke detection systems to help keep homes safe.
