Gas, fire, smoke detectors, heat detectors, and fire alarms trigger alarms upon detection of a relevant event. Smoke/gas detectors are increasingly using wireless technology to communicate with other devices.
Silicon Labs Solutions
Customer Benefits
Low power operation:Industry's lowest power solutions for MCU and wireless control
Extremely long battery life and fewer battery replacements
Single pulse proximity sense architecture
Enables measurement to be made with one, very short 25.6 µs burst of the irLED
Fast and flexible processing unit: Industry-leading MCU solutions (highest performing, integrated ADCs, flexible GPIOs)
Customer can implement a sophisticated sensing algorithm that will look for changes over time
Wireless range and robustness: Industry-leading wireless solutions (highest sensitivity, longest range, lowest system cost)
Customer can reliably send alarm, trouble and low battery messages to alarm panel (or dialer)
Infrared Sensors: High sensitivity, low power infrared sensors
Reduce mechanical complexity of the smoke chamber
Reduced false detections
The differential measurement method takes a measurement with the irLED on and then with it off in order to compensate for ambient light effects, and can help identify false positive such as insects
Simplified bill of materials
Unlike passive optical systems, specially constructed, complex, and bulky smoke chamber are not required in order to detect smoke
No radiation
Environmentally conscious optical based systems steer away from potentially hazardous ionization type detectors
