Abstract
An electronic device for sensing gas present in the environment, comprising a presence sensor for the gas concentration, a digital electronic circuit for processing data, a permanent random access memory, a bidirectional serial logic gate, at least one optical and/or acoustic warning device, and an electrical actuator or relay. During its production the electronic device receives from an external processor, via a serial line, data (gas concentration, temperature, humidity) relating to the environment in which the sensor is located, the data being analyzed by the digital electronic circuit together with the values present at the output of the sensor, for the purpose of calibrating the device.
