Indicator, Temperature, Temperature indicator circuit

The multimeter is a measurement device most used by engineers and we use it in this temperature indicator circuit schematic. The temperature sensor is LM335 wich has a linear characteristic of 10mV / K . In the production process this electronic device is calibrated so can provide 2.73V at 0⁰C.

LM336 is used as a very precise 2.5V Zener diode; CA3040 amplification can be adjust between 1.08 and 1.10 times thru P1. This temperature measurement circuit can be used for Fahrenheit measurements, in this case the freezing point is adjusted at 32⁰F. At 212⁰F, P2 is adjusted to obtain 0.9V at output.
So 1⁰F correspond to 5mV. The total current consumption is 10mA.

Mock Flasher LED circuit

This simple Mock Flasher LED simulates the indicator of a sophisticated Alarm system. It can be placed in doors, gates and vehicles to confuse intruders. The circuit is too simple using a Unijunction transistor as an oscillator.

Uni junction transistor (UJT) is an electronic semiconductor device that has only one junction. The UJT has three terminals: an emitter (E) and two bases (B1 and B2). The base is formed by lightly doped n-type bar of silicon.Two ohmic contacts B1 and B2are attached at its ends. The emitter is of p-type and it is heavily doped. The resistance between B1 and B2, when the emitter is open-circuit is called inter-base resistance. The 2N2646 is the most commonly used version of the UJT.

UJT 2N2646

UJT Pin Connection -Bottom View

Working of UJT

The UJT is biased with a positive voltage between the two bases. This causes a potential drop along the length of the device. When the emitter voltage is driven approximately one diode voltage above the voltage at the point where the P diffusion (emitter) is, current will begin to flow from the emitter into the base region. Because the base region is very lightly doped, the additional current (actually charges in the base region) causes conductivity modulation which reduces the resistance of the portion of the base between the emitter junction and the B2 terminal. This reduction in resistance means that the emitter junction is more forward biased, and so even more current is injected. Overall, the effect is a negative resistance at the emitter terminal. This is what makes the UJT useful, especially in simple oscillator circuits.

Working of Mock Flasher LED

UJT 2N 2646 is used as a simple oscillator with the oscillating components R1 and C2. The LED is connected between the base2 (B2) of the UJT and the ground. Resistor R2 restricts current through the UJT as well as LED. At power on, capacitor C2 charges through R1 and when it fully charges, emitter of UJT forward biases and current flows into the base. LED then lights. The discharge of C2 is followed by its charging again creating an oscillating cycle so that LED flashes.

Sound-Level Meter

Meter, Sound-Level

The NE604`s signal-strength indicator section is used, based on an internal logarithmic converter. This enables a linear

decibel scale so that the moving-coil meter (shown in the diagram) can be replaced by a digital instrument. The signal source is assumed to be an electret microphone that converts ambient noise into an electrical signal. Because this type of microphone normally contains a buffer stage, R7, R8, and C13 have been included to provide the supply voltage for this stage. The NE604 delivers an output current (at pin 5) of 0 to 50, which causes a potential difference across R2 R3 of 0 to 5 V. The input and output signal range is equivalent to a sound range of 70 dB. lb compensate for the effects of temperature changes, the required resistance of 100 KOhmhm is formed by two resistors (R2 and R3) and a diode (Dl). Any ripple remaining on the output voltage is removed by R4/C9/C10 before the output is buffered by IC2. The indicating instrument, here a moving-coil meter, is connected to the output (pin 6) of IC2 via a series resistance, R^ . The preset is adjusted to give full-scale deflection (FSD) for an output voltage of 4 V. Calibrating the meter is a little tricky, unless you have access to an already calibrated instrument. Otherwise, if you know the efficiency of your loudspeaker, that is, how many decibels for 1W at 1 m, you can use that as reference. The scale of the meter can then be marked with the (approximate) value. In any case, the meter deflection must at all times be seen as an indication, not as an absolute value: it was not thought to be worthwhile to add a filter to the circuit to enable absolute measurements to be made.

The circuit essentially provides low-frequency boost below 318 Hz and high-frequency attenuation above 3150 Hz.

Recent modifications to the response standard include a 31.5-Hz peak gain region to reduce de-oriented distortion from external vibration.

Diac controlled LED flasher

Diac, LED Flasher

This is probably the simplest idea to generate flashing light from an LED using AC. The circuit is relatively the simple way of flashing one or more LEDs from a high voltage DC obtained from Mains. This can be used as a Mains indicator or Mock flasher.

The circuit uses a diac for the alternate switching of LED. The diac is usually used in pulse generator circuits to trigger SCR and Triac. If a low voltage passes through a diac, it simply behaves like an open circuit and only very low current passes through it. But if the voltage increases to the breakdown threshold of the diac, it will pass heavy current. Usually 35 volt DC is required to attain the threshold level of diac. Unlike SCR, diac conduct in both the directions. In the circuit, a commonly available DB3 diac is used. Diode D1 rectifies AC and generates a high volt DC. Resistor R1 safely controls the DC to operate diac and LED.

Normally LED will be OFF. When the capacitor charges fully, diac gets the threshold voltage and fires. This provides current to LED and it lights. Resistor R2 makes the LED current to a safer value of 30 mA. When the diac conducts, C1 discharges and again the breakdown voltage of diac decreases and LED turns off. Thus the charging/discharging cycles of C1 makes the LED flashing. The value of C1 determines the flash rate. Higher values give slow flash rate and vice versa. If the threshold level of diac is not obtained using the given value of R1, reduce it to 10K, but its wattage should be increased to 5 watts.

CautionThe circuit is directly connected to high volt AC and there is no galvanic isolation. Take utmost care while handling the circuit. Enclose it in a shock proof case. Do not touch any points when it is connected to Mains.

LED Alarm Simulator circuit

This circuit simulates an alarm to discourage thieves and it is originally designed to be used on bicycles but can be used for cars too. It blinks a LED on and off thus simulating a real alarm circuit.

The LED alarm electronic circuit consists of a square wave oscillator generating a 1 MHz signal with a pulse width of 10 milisecond. The LED lights u 10 miliseconds long. The circuit consumes 30 miliamperes when the LED lights and the average consumption is 300 microamperes.

To switch off the circuit automatically it has a built in LDR. When the LDR is exposed to light it becomes low ohmic and the output of U1 becomes 0. The oscillator stops and the LED turns off. The light sensitivity of the circuit is set with the potentiometer P1.

When there is no light falling on the LDR, the input of U1 is connected to the ground and its output becomes “1″ thereby starting the oscillator which drives the LED to blink. If the circuit is powered with a 4.5 volts battery that has a 2 Ah capacity, it will work for aroung 1.5 years.

Electronic head or tail circuit

Electronic head, Electronic head or tail circuit, tail

The principle used in this electronic head or tail circuit is simple: a multivibrator controls a flip flop. The multivibrator oscillates as long as the buton S1 is pressed and the flip flop switches on and off with a frequency of several kilohertz. When the button is released, a 5 volts is set at one of the two gates that makes up th multivibrator. The flip flop latches on at one of the two possible states: “head” or “tail”.
The state of the flip flop is dependent on the exact time when the button S1 was released. because the speed of the flip flop’s switch overs and the relative inertia of the human reaction, the state at which the flip flop latch is random.

The entire circuit is made up of a single 7400 IC. It is important to decouple the circuit and the display bulbs very well to avoid reverse voltages and currents that appear during the switching off of the display bulbs.

The capacitor C5 (not shown in the schematic diagram) is a 250 uF electrolytic capacitor rated at 10 volts.
