HC-SR501 with LDR attached to it. - Sensors - Arduino Forum

· Sounds a very overengineered solution to just adding the LDR to the PIR sensor directly. If you want better control for the darkness level at which it switches - which is based on the resistance of the LDR, low resistance is light, high resistance is dark - it may work to add a 100k pot. Then all that’s left is the latching relay, that’s also a routine circuit. Easiest is if you have a ...

Testing and Playing with PIR sensors (motion sensor)

· In one of my current projects, I’d like to use a few motion or proximity sensors, also known as PIR sensors. PIR sensors, or Passive Infra Red sensors, can be great for Arduino and Raspberry Pi projects, and can be bought really cheap – I only paid about a dollar per sensors in bundle of 10 PIR sensors from eBay, but you can get them really cheap at places like Amazon or AliExpress as well.

PIR sensors: HC-SR501 - IoT Experiments

· This trick will not decrease a lot the power consumption of the PIR sensor, but it will be possible to use it directly with some 3V batteries (like a CR3032). Add a LDR. The circuit uses a BISS0001 chip to manage the PIR sensor. You can find the schematics in the datasheet of the module. We can see that the LDR pads connects to pin 9 of the BISS0001. According to the datsheet that pin …

Motion Sensor With LDR | All About Circuits

· When I put a resistor between Q2 base and the PIR output - R4 node, the PIR still detects motion when it's light. Also, I think I may have mistaken the blinking business in my original post with the stabilization that the PIR sensor does. It seems if I wait a couple minutes, the blinking stops. Then only the PIR detects legitimate motion. But again, the circuit was set-up to NOT detect ...
