Heat Sensor Circuit Diagram
This simple heat sensor circuit could senses heat from various electronics device like computer, amplifier etc. and generate warning alarm. It could senses heat from environment also, but here I mention “electronics device” because it is being using mostly in electronic device to protect them from overheat.
Circuit diagram of heat sensor:

Thermistor, 110 Ohms:

| Fig-2: 110 Ohms Thermistor |
As it is a heat sensor circuit, here a thermistor is used as a heat sensor. It is a thermal measurement device and has a variety of usages including temperature sensor/ heat sensor. The thermistor used in this circuit is a NTC (Negative Temperature Coefficient) type thermistor. When temperature increases, its resistance goes decrease. Therefore, NTC thermistor’s resistances are inverse of temperature.
Circuit Description:
You have seen, in this simple circuit diagram of heat sensor, a few number of components is used including a BC548 transistor, a 110 ohms thermistor etc.- BC548: BC548 is a TO-92 type NPN transistor, as its alternative you can use 2N2222, BC238, BC548, BC168, BC183 etc. they all have almost same characteristic.
- 110 Ohms Thermistor: A 110 Ohms thermistor is used to detecting heat. I have told already about it.
- Buzzer: A buzzer is used with +9V and collector of transistor. When the temperature/ heat exceeds a certain level then it make an alarm.
- 4.7V Zener diode: It is used to limit the emitter current of BC548.
- 9V Battery: A 9V battery is used as a single power source.
- R1, R2: A 3.3K 1/4w resistor is used as R1 and 100 ohms 1/4w as R2.
- Switch: Here in this circuit the switch used is a simple SPST switch. You can either use the switch or not, choice is yours. It is not mandatory.

SEMICONDUCTOR FMS6363 LOW COST VIDEO FILTER ELECTRONIC DIAGRAM
SEMICONDUCTOR FMS6363 LOW COST VIDEO FILTER ELECTRONIC DIAGRAM
The FMS6363 Low Cost Video Filter (LCVF) provides 6dB gain from input to output. In addition, the input will be slightly offset to optimize the output driver performance. The FMS6363 provides an internal diode clamp to support AC-coupled input signals. If the input signal does not go below ground, the input clamp will not operate. This allows DAC outputs to directly drive the FMS6363 without and AC coupling capacitor (usually 220 ?F). The offset is held to the minimum required value to decrease the standing DC current into the load.

BURGLAR ALARM USING IC TIMER 555 556 ELECTRONIC DIAGRAM
BURGLAR ALARM USING IC TIMER 555/556 ELECTRONIC DIAGRAM
circuit diagram of burglar alarm using IC timer 555/556 is functioned as an alarm to prevent thief entering your house. The alarm would produce loud sound when a thin wire connecting resistor R1 with IC pin no 4 is broken. Thin fiber is used as the wire. The thinner the wire, the more responsive the alarm. This circuit needs 5-15V power supply, buzzer is used as a speaker. Here is the circuit schematic :
Parts list :
- Resistor R1 : 10k
- Resistor R2 : 68k
- Resistor R3 : 1k
- Polar capacitor C1 : 1uF/15 B
- Capacitor C2-C3 : 0.01uF
- IC Timer : NE555

Simple Cold Cathode Fluorescent Lamp Supply Circuit Diagram
Simple Cold-Cathode Fluorescent-Lamp Supply Circuit Diagram. For back-lit LCD displays, this supply will drive a lamp. LT1072 drives Ql and Q2, and a sine wave appears across CI. LI is a transformer that steps up this voltage to about 1400 V. Dl and D2 detect lamp current and form a feedback loop to the LT1072 to control lamp brightness. C1 = MUST BE A LOW LOSS CAPACITOR. METALIZED POLYCARB WIMA FPK 2 (GERMAN) RECOMMENDED. L1 = SUMIDA 6345-020 OR COILTRONIX CTX110092-1. PIN NUMBERS SHOWN FOR COILTRONIX UNIT. L2 = COILTRONIX CTX300-4 * = 1 % FILM RESISTOR.
