The entire circuit of microphone amplifier is build around operational amplifier 741. Op-amp 741 can be used in both inverting mode and non inverting mode according to necessary. Here we use 741 in inverting mode because at inverting mode input impedance is low. A microphone is a transducer which changes sound energy into electric signal. Microphone detects sound and changes it into electric signal which is very weak and need amplification before given to loudspeaker. The output of microphone is given to pin 2 of IC₁ through resistor R₁ as shown in circuit diagram. The output is taken from pin 6 of IC₁. The value of amplified output is equal to R₁/R₂ where value of resistance R₁ is set according to impedance of microphone. Here we used resistor R₄ as load resistor. This output connected to a microcontroller through a transistor based amplifier. That microcontroller detects signal from the amplifier and toggle its output. That output is connected to a TRIAC based relay. 230v load is connected through relay. Here we control the high voltage load using a low voltage by this relay. A MOC3021 ic is connected between microcontroller and relay for isolation.

Nowadays most of the countries are forcing the motor riders to wear the helmet and not to use the vehicles when the person is in drunken condition. But still the rules are being violated by the users. In order to overcome this we introduces an intelligent system, Smart Helmet, which automatically checks whether the person is wearing the helmet and has non- alcoholic breath while driving. Here we have a transmitter at the helmet and the receiver at the bike. There is a switch used to sure the wearing of helmet on the head. The ON condition of the switch ensures the placing of the helmet in proper manner. An alcohol sensor is placed near to the mouth of the driver in the helmet to detect the presence of alcohol. The data to be transferred is coded with RF encoder and transmitted through radio frequency transmitter. The receiver at the bike receives the data and decodes it through RF decoder. The engine should not ON if any of the two conditions is violated. MCU controls the function of relay and thus the ignition, it control the engine through a relay and a relay interfacing with the circuit.

Here we have designed a smart gate which operates after sanitizing your hand automatically. Here is an automatic sanitizer dispenser works with a proximity sensor which output is connected to both sanitizer dispenser and motor of the gate. When washing hands, the user’s hands are placed under the nozzle and before the sensor. The activated sensor will further activate a pump that dispenses a premeasured amount of liquid from the nozzle. This kind of sensor sends out bursts of microwave or ultrasound energy and waits for the energy to reflect back. In a stagnant situation, the energy will bounce back in a normal pattern. When hands are placed in the basin, the energy emitted from the sensor will bounce back irregularly which triggers the dispensation of liquid and operates the gate.
