Electronic device for the use of a very low voltage source and its application in a fire detector-emitter

摘要

to solve the problems related to the difficulty of making the maintenance of sensors placed at different locations are less accessible and / or divided into very many points of an area.the electronic device includes an arrangement which provides power to a transmitter (e) independently from a transducer (ct).the arrangement includes at least one transistor (t21, t22, t23) and a processor (26), and the low number of primary coil is in series with the line operated from the transistor.the secondary of the transformer, the greatest number of turns.the control electrode is on and the low voltage transistor is applied to the section order transistor in series with the primary winding of the transformer.tensions are already applied some mv and the appearance, at the terminals of the secondary winding, a voltage pulse of a magnitude ".which can accumulate energy in a capacitor (25) of the transmitter (e) intermittently.;this is a very interesting application for the realization of autonomous sensor transmitter remote fire alarm.
