How to Automate Your Home With a PIR Motion Sensor ...

· Connect the PIR motion sensor's Vcc and GND to the 7805's output. Connect the BC547 (pin out - Collector, Base, Emitter) collector to one end of the relay coil. Connect the base to the PIR motion sensor's output signal and the emitter to theGNDd. The other end of the relay's coil is connected to the input voltage (9V).

Triggering 12v Relay with HC-SR501 PIR sensor - Electrical ...

· So you are connecting n PIR sensor to a relay, but it is not clear which is making trouble, or both are. First thing first is to do a structured analysis: I suggest to eat the big elephant byte by byte, in two bytes: PIR byte, and Relay bite. Now decouple (I mean, separate, or put one aside) the two modules and look at the PIR guys first. Only after making sure PIR is OK, then you eat your ...

5v - How to trigger a Low-level relay with PIR sensor ...

· Triggering 12v Relay with HC-SR501 PIR sensor \$\endgroup\$ – Andy aka Aug 21 '20 at 11:13. 1 \$\begingroup\$ Some relay modules have a built-in transistor to engage the relay when Vin = high. It is unclear how this module works and if it has that transistor. Also realize that the relay switch has 3 contacts, two of these go open when the relay is engaged. \$\endgroup\$ – Bimpelrekkie Aug ...
