How To Make Smoke Detector Alarm Circuit - Electronics Hub
Smoke Detectors are amazing devices as they are small, cheap yet very useful. In this project, we implemented a simple Smoke Detector Circuit with adjustable sensitivity. We used a Smoke Sensor MQ-2 as the main sensory device. The working of the circuit is simple and is explained below. LM358 acts as a comparator in this circuit.
Simple 12 volt Battery Charger Circuit Diagram

You can use this circuit to charge 12V SLA battery or 12V Gel cell battery and so on. This circuit is designed to provide charging current upto 3 amps and this circuit don’t have reverse polarity protection or over
LDR Circuit Diagram - Build Electronic Circuits
This LDR circuit diagram shows how you can make a light detector. An LDR or “Light Dependent Resistor” is a resistor where the resistance decreases with the strength of the light. Here is the schematic for the circuit:
Simple Latch Circuit Diagram with Transistors
In Electronics, Latch Circuit is a circuit which locks its output, when a momentarily input trigger signal is applied, and retains that state, even after the input signal is removed. Here is a simple latching circuit built by using transistors.

Heat Sensor Circuit And Its Working Principle
Heat Sensor Circuit. 110 Ohms Thermistor: It is used to detect the heat. BC548: BC548 is an NPN transistor TO-92 type. We can use other alternatives like 2N2222, BC168, BC238, BC183, etc. because the characteristics are almost the same for these types of transistors. Buzzer: A buzzer is between the +9V battery and the collector terminal of the transistor. . When the temperature exceeds a
