I need help with something I'm building because I've hit a dead end. I need this PIR sensor.
To activate this pump off a 9v battery.
The problem is the power output from the sensor isn't enough to power the pump. I tried a transistor but still nothing and all my research has led me no where. I wired it up from a similar question asked on this site but it's still not working.
If anyone has any simple advice it would be greatly appreciated as I have zero knowledge of these things and only going on what I've researched off the internet. Thanks.
