ADPD188BI-ACEZR7 Optical Smoke Detector Module ADI Brand for Smoke Detection
Description
The ADPD188BI is a complete photometric system for smoke detection using optical dual waveleCM GROUPh technology. The module integrates a highly efficient photometric front end, two light emitting diodes (LEDs), and two photodiodes (PDs). These items are housed in a custom package that prevents light from going directly from the LED to the photodiode without first entering the smoke detection chamber
FEATURES and BENEFITS
3.8 mm × 5.0 mm × 0.9 mm module with integrated optical components
1 blue LED, 1 IR LED, and 2 photodiodes
2 external inputs for other sensors (for example, carbon monoxide (CO) and temperature)
Three 370 mA LED drivers
20-bit burst accumulator enabling 20 bits per sample period On-board sample to sample accumulator enabling up to 27 bits per data read
Optimized SNR for signal limited cases
I2C or SPI communications
Applications
