Hack Every-Day With Simple Hack

This Post only for demonstrate how a make a Fire sensor using Transistor and detect fire  .. Its easier to make a Fire alarm project With this circuit. Ill make a project at future with this..  Requirement Components:   1. transistor 2x BC547  2. LED  3. 3 Register 10k Ohm 2x  + 18k Ohm 1x 4. 9v Battery + battery Clip (You can use less or more then 9v , just need to change Resister with battery voltage. i prefer battery voltage should be between 6-12v). 5. some wires . normally use jumper cables. NB:  Here I used Read LED , this led more voltage tolerant then white LED . so you must choose more Ohms Register for ignore fusing your LED.  Circuit Diagram: How Diagram work:   when the 3 number register's coil worm up a small current flow through base and on the other hand the first transistor collector already got current , so base current with collector current make flow emitter current which flow towards...

This Post only for demonstrate how a #LDR work and using a single #LDR and #Transistor make dark detection sensor .. Its easier to make a Security alarm project from this circuit. Very recent I'll share similar project with this circuit. Components For Dark Sensor Circuit Requirement Components:   1. transistor BC547 2. LDR (Light Dependent Register ) 3. LED  4. 3 Register 10k Ohm 2x  + 18k Ohm 1x 5. 9v Battery + battery Clip (You can use less or more then 9v , just need to change Resister with battery voltage. i prefer battery voltage should be between 6-12v). 6. some wires . normally use jumper cables.  Circuit Diagram: Circuit Diagram For Dark Sensor Circuit How Diagram Work:  BC547 NPN transistor is most use full and Cheap Electronic component with have 3 pins  Emitter,Base and collector, when supply current through this transistor for base and collector current emitter flow current while base emitter disc...
