Hey man, that's a cool tip thank you. And even though the image sensor itself is only comprised of 1000 pixels, I think we can all appreciate the fact that Hodgins placed and soldered each and every photo cell by hand. Did you make this project? detect when someone walks through a door, or when someone's hand gets
Connecting a lamp or alarm to it to be alerted when the sensor moves is therefore difficult. If the signal LED is OFF, then your sensor is OK for now, otherwise gently turn the potentiometer knob on the sensor in anti-clockwise direction using a screwdriver, such that the LED turns OFF. The PIR sensor itself The IR sensor itself is housed in a hermetically sealed metal can to improve noise/temperature/humidity immunity. resistance according to some particular property of the environment. So rather than trying to weatherproof the sensor itself, unless there is a manufacturer – approved method, just put it in an electronics “project box” approved for your location with the air gap on the bottom (that’s how they’re designed generally anyway). Hall Effect (magnetic
the brighter the LED. Climb the ladder to reach the light, taking care not to set the sensor off. You need to solder the ball and the spring together like you can see it on the picture. Connect the resistor and LED in series from the positive supply to the collector of the transistor. your sensor has no resistance (like a piece of wire). Effect sensor (from digikey.com, part number DN6848-ND). Higher the intensity of the radiation falling on the photodiode, higher will be the output voltage. For example if our sensor has a resistance of
