A well filtered power source of from 3 to 15 volts should be connected to the FET drain terminal pin 1. The PIR325 sensor has two sensing elements connected in a voltage bucking configuration. This arrangement cancels signals caused by vibration, temperature changes and sunlight. A body passing...
The PIR sensor stands for Passive Infrared sensor. It is a low cost sensor which can detect the presence of Human beings or animals. ThisHC-SR501 PIR sensor modulehas three output pins Vcc, Output and Ground as shown in the pin diagram above. Since the output pin is 3.3V TTL logic it...

The block time is the time interval where the sensor is disabled or will not detect motion. The block time for HC- SR501 is 3 seconds by default. This occurs after the delay time (which was set by timer knob) the output goes LOW for 3 seconds; during this interval no motion will be...
