PIR sensors are rather generic and for the most part vary only in price and sensitivity. Most of the real magic happens with the optics. This is a pretty good idea for manufacturing: the PIR sensor and circuitry is fixed and costs a few dollars. The lens costs only a few cents and can change the breadth, range, sensing pattern, very easily.

20210718· The PIR sensor stands for Passive Infrared sensor. It is a low cost sensor which can detect the presence of Human beings or animals. This HCSR501 PIR sensor module has three output pins Vcc, Output and Ground as shown in the pin diagram above. Since the output pin is TTL logic it can be used with any platforms like Arduino, Raspberry, PIC, ARM, 8051 etc..

20180419· The PIR sensor module can be divided in to two parts an infrared sensitive crystal and the processing circuit. Illustration of PIR sensitive crystal: The dark portion of the metal where the IR sensitive crystal is housed, the sensitive crystal can detect the level of infrared in the surroundings. It actually houses two pyroelectic sensors for detecting moving objects. If one of the sensitive ...

Los detectores PIR (Passive Infrared) o Pasivo Infrarrojo, reaccionan sólo ante determinadas fuentes de energía tales como el calor del cuerpo humano o animales. Básicamente reciben la variación de las radiaciones infrarrojas del medio ambiente que cubre. Es llamado pasivo debido a que no emite radiaciones, sino que las recibe. Estos captan la presencia detectando la diferencia entre el ...

Los sensores de radiación infrarroja pasiva, también llamado sensor PIR, son capaces de detectar el calor generado por un cuerpo humano en movimiento. Cuando se dice que es pasivo, se refiere a que el dispositivo responde a la radiación recibida en lugar de enviar una señal o escanear una zona determinada. Por medio de un meticuloso filtrado de la señal de calor entrante, un sensor PIR ...
