Summary

Parallax Inc. 28091 is used in Ambient Light, IR, UV Sensors category where placement, interface fit, and operating envelope drive measurement reliability. Key specs include Description (SENSOR OPT UV MODULE), Type (Ultraviolet (UV)), Output type (Analog), Package/case (Module), and Mounting (User Defined: Chassis Mount).

Selection Notes
  • For 28091, ensure the supply range (3.3V ~ 5V) is compatible with your power tree and tolerance budget.
  • Match the output type (Analog) when selecting alternates or second sources.
  • Confirm Proximity Detection (No) meets your design constraints and system-level expectations.
  • Ensure the package/case (Module) and land pattern match your PCB layout before procurement.
Alternates & Substitutions
  • For Ambient Light, IR, UV Sensors, compare the datasheet test conditions behind key specs and re-check the margins that were tightest during bring-up.
  • Check that supply 3.3V ~ 5V matches your system, then validate at corners instead of relying on typical values.
  • Start by confirming the physical match (package/case Module, mounting User Defined: Chassis Mount, packaging Bulk) so the swap does not create a footprint risk.
  • When in doubt, treat the swap as an ECO: define acceptance criteria, then validate under worst-case operating corners.

Application Scenarios

Parallax Inc. 28091 is listed under the Ambient Light, IR, UV Sensors category and is commonly used when correctness, reliability, and qualification repeatability matter. Environmental sensing focuses on drift, response time, contamination exposure, and compensation so readings remain meaningful over life. Reliable environmental sensing enables better automation decisions and reduces operational risk. They monitor conditions such as temperature, humidity, light, gas concentration, or particulates for safety and efficiency. Within data centers, distributed sensing improves hot-spot detection in constrained airflow channels between racks. In industrial safety, gas and smoke sensing is treated as a reliability problem, so calibration and drift behavior are validated over time. Across smart buildings, environmental sensors drive HVAC optimization in ceiling nodes exposed to dust and changing airflow patterns. When margins are designed in, performance tends to stay stable even when operating conditions are not ideal.

Compatibility Advice
  • In qualification work, verify long-term stability and condensation exposure if the product sees outdoor or humid environments. This reduces the chance that substitutions push hidden limits.
  • In practice, verify environmental stress assumptions (temperature, humidity, contamination) so sensing remains repeatable over life before committing to volume builds.
  • Validate noise and latency with production-like cabling so the system behaves the same outside the lab across temperature and supply corners.
Project Fit
  • Good fit when you can qualify Parallax Inc. 28091 for Ambient Light, IR, UV Sensors integration with production-like fixtures, and you can validate drift and response time in the real airflow and enclosure environment.
  • Poor fit when the input environment is poorly controlled and cannot be replicated for validation, because integration risk stays high when key margins cannot be measured.
