Abstract:
(EN) Provided is a sensor, the power consumption of which can be reduced as compared with conventional sensors. A sensor 1 is provided with a photoelectric conversion element 2a that generates an output signal by receiving light, and an oscillation circuit 3 that converts the output signal into a pulse density modulation signal, thereby making it possible to output a pulse density modulation signal corresponding to the output signal without a battery. As a result, in the sensor 1, the pulse density modulation signal can be generated as a pulse signal without using an AD converter or the like for converting an analog signal into a digital signal. Therefore, analog-to-digital conversion processing by the AD converter becomes unnecessary, and power consumption can be accordingly reduced as compared with conventional sensors.
(FR) L'invention concerne un capteur, dont la consommation d'énergie peut être réduite par comparaison avec des capteurs classiques. Le capteur (1) est pourvu d'un élément de conversion photoélectrique (2a) qui génère un signal de sortie en recevant de la lumière, et d'un circuit d'oscillation (3) qui convertit le signal de sortie en un signal de modulation de densité d'impulsion, ce qui permet de délivrer en sortie un signal de modulation de densité d'impulsion correspondant au signal de sortie sans batterie. En conséquence, dans le capteur (1), le signal de modulation de densité d'impulsion peut être généré sous la forme d'un signal d'impulsion sans faire appel à un convertisseur AN ou analogue pour convertir un signal analogique en un signal numérique. Par conséquent, le traitement de conversion analogique-numérique par le convertisseur AN devient superflu, et la consommation d'énergie peut être réduite en conséquence par comparaison avec des capteurs classiques.
(JA) 従来よりも消費電力を低減し得るセンサを提供する。センサ1では、光を受光することで出力信号を生成する光電変換素子2aと、出力信号をパルス密度変調信号に変換する発振回路3とを設けることで、電池レスで出力信号に応じたパルス密度変調信号を出力できる。これにより、センサ1では、アナログ信号をデジタル信号に変換するADコンバータ等を用いずに、パルス信号としてパルス密度変調信号を生成できるので、ADコンバータによるアナログデジタル変換処理が不要になる分、従来よりも消費電力を低減し得る。
