Honeywell has introduced a new device that allows manufacturers of fire and security detection technologies to design smaller, less obtrusive wireless-based products without sacrificing reliability or performance.
The new Anisotropic Magnetoresistive (AMR) Sensor ICs, Nanopower Series have higher sensitivity and more reliability than “traditional” sensors, yet consume less energy. They are also smaller and therefore allow greater flexibility in design at a lower cost.
Typical product applications include smoke detectors and door/window alarms. In the case of the latter, the sensor will immediately send a signal to a wireless module that transmits that signal to a central control unit for processing as soon as a door or window is opened, removing the magnet out of the sensor detection range. On smoke detectors, the sensor is used as an alarm test switch where an external magnet is brought in the detection range of the sensor to check correct...
