PIR Motion Sensors Tasmota

PIR Motion Sensors. PIR motion sensors, albeit called sensors, are configured as switches in Tasmota since they basically report motion ( 1) or no motion ( 0) to the device. Most PIR''s are single wire and they require connecting to VCC, GND and one GPIO. In this guide we will use GPIO13 as the pin that the PIR output is connected to.

OS 8 TIPOS DE SENSORES E AS SúAS CARACTERíSTICAS CIENCIA

É un tipo de sensor que funciona só en espazos onde hai presenza de aire, xa que o desprazamento da onda sonora só pode producirse neste medio. Por outra banda, é útil para detectar obxectos independentemente do seu estado (sólido ou líquido) ou da súa cor, polo tanto, son excelentes para tarefas de seguimento ou medición de distancia.

How PIRs Work | PIR Motion Sensor | Adafruit Learning System

Jan 28, 2014· 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.
