HCSR501 PIR sensor power consumption - Sensors - Arduino Forum

· I am trying to calculate the expected power consumption of an Uno R3 running a simple script that polls a PIR sensor every second or so. I know a full Uno board uses roughly 50mA (250mW). I have also seen someplace that the HCSR501 PIR sensor uses at most (when it is active and detecting a "body") 150uA.... or Is this right? Is the power consumption of the PIR sensor in worst …

PIR sensor for battery powered and low power applications

· Design complexity: If you end up making a low power PIR sensor with a suitable operating range, it often ends up using nano-power opamps. Because of the ultra low current involved, the circuits can be expensive and sensitive to EMI. Even though it does allow the power consumption to go under 2uA if designed the right way (will last 8+ years on a CR2032 coin cell!).

Understanding Active & Passive Infrared Sensors (PIR) and ...

· Passive infrared (PIR) sensors use a pair of pyroelectric sensors to detect heat energy in the surrounding environment. These two sensors sit beside each other, and when the signal differential between the two sensors changes (if a person enters the room, for example), the sensor will engage. That may mean it triggers an alarm, notifies authorities, or maybe turns on a floodlight. IR radiation ...
