The following components were used to construct the circuit: antiparallel diodes BAV199-7-F , 3Mb / 56P. Lead-wire resistance connecting the sensor and the microcontroller were 10.5 each, corresponding to a 30 AWG copper wire of about 30 m length. Sensor resistance R X was increased from 100 to 150 corresponding to the temperature range of 0 to 131 ☌ of an RTD Pt-100. 1 was experimentally verified. The LM358 is a low power dual operational amplifier integrated circuit originally introduced by National Semiconductor.The working of circuit shown in Fig. Replacement / Equivalent / Other Part Numbers:For more guidance, see Wikipedia:Translation.
Working of Single Axis Solar Tracking System using LM358The LM358 contains two independent high gain operational amplifiers, low power, dual channel op-amp, high gain with internal frequency compensation. LM358 based Solar Tracker Circuit Wiring Single Supply and Dual Operational Amplifiers: Low Power Dual Operational Amplifier Large DC voltage gain: 100dB. Old version datasheet DUAL OPERATIONAL AMPLIFIERS.
Generally we obtain signal from sensor are usually have small rating. LM- The low power drain also makes the LM358 a good choice for battery operation. It consists of 8 pins which contains two operational amplifiers.In this IC we have two operational amplifier which can we use as a comparator. It can handle voltage from 3V to 32V DC supply and current up to 20mA per channel. The device has low power supply voltage.LM358 IC can also be used as transducer standard operational amplifier and it is suitable for our needs. We can also use a split power supply.
Then this IC will decide whether the voltage is greater or less than reference voltage by giving output high or low.The LM358 is a versatile uses it can be used as comparator to compare different signals, amplifying signals from a variety of transducers or sensors to dc gain blocks or any op-amp function.*Please Note: These are affiliate links. The LM-358 IC get signal from the sensor and compare to the reference voltage. By using 0.3V we cannot ON/OFF led or relay.
Thus a sine was applied to the inverting input, will appear inverted at the output. Inverting input:The operational amplifier inverting input is marked by a “-” sign on the circuit diagram in LM-358 the inverting input is pin number 2.A negative voltage swing will be produce when positive a positive voltage is applied at the inverting input. If a changing waveform, such as a sine wave is applied to the non-inverting input such as pin number 3 in LM-358, then it will appear in the same sense at the output. It is found that a positive voltage applied to the non-inverting input then it will not be change and it will produce a positive swing at the output. Non-inverting input:The operational amplifier non-inverting input is marked by a “+” sign on the circuit diagram in LM-358 the non-inverting input is pin number 3. I would appreciate your support in this way!This pin is the output of first operational amplifierThis pin is the inverting input of first op-ampThis pin is the non-inverting input of first op-ampThis pin is the non-inverting input of second op-ampThis pin is the inverting input of second op-ampThis pin is the output of the second op-ampThis pin is the positive voltage supply to both op-ampAn Operational Amplifier, or op-amp for short, is fundamentally a DC coupled high gain voltage amplifying device they are ideally designed for signal conditioning, DC amplification, filtering and to be used with external feedback components such as capacitors and resistors between its output and input terminals.The op-amp perform different function depending upon its feedback configuration whether it resistive, capacitive or both on the bases of this it can be used differential amplifier, integrator or summer.
Two Op-amps, compensated internally we can use both op-amp at a time or if we need only one op-amp we can used it. LM-358 is Compatibility with all forms of logic. There is no need separate supply to the op-amp Available packages: TO-99, CDIP, DSBGA, SOIC, PDIP, DSBGALM-358 has different advantages, a few of which are given below. Soldering pin temperature – 260 ˚C (for 10 seconds – prescribed)
General signal conditioning because it can be used as comparator it compare two signals DC gain block due to which it has minimum interference to RF signals Permits direct sensing close to GND & VOUT
Current loop transmitters for 4 to 20mA. Active filters because it remove noise from the signal General signal amplification it amplify signal

From our household experience, we have known LEDs that emit visible light. IR led send out light longer than visible light. The voltage of pin 2 will be compared with that of pin 3, and the voltage of pin 6 is compared with that of pin 5, corresponding to two independent outputs: 1OUT and 2OUT.When the input at non-inverting (+) pin 2 is greater than input at inverting input (-) pin 3, similarly When the input at non-inverting (+) pin 5 is greater than input at inverting input (-) pin 6 the output of both op-amps will be high.When the input at non-inverting (+) pin 2 is less than input at inverting input (-) pin 3, similarly When the input at non-inverting (+) pin 5 is less than input at inverting input (-) pin 6 the output of both op-amps will be low.No pull-up resistor is required at the output of LM358.LM358 Based projects: IR Proximity sensor with LM358:An IR led is solid lightning device that emits some form of electromagnetic radiation when powered up. Pin 8 is main power supply input.LM-358 contains two operation amplifier the input of the first amplifier is pin 2 and pin 3 and the output is pin 1, if we want to use the second amplifier the input for this amplifier is at pin 5 and 6 and the output is at pin 7.If we want to compare two signals then we will give one signal at pin 2 and the other signal at pin 3. If we want to use the LM-358 as operational amplifier then we will give the voltage from ☑.6V to ☑6V.
So , it is very important that the IR photodiode used must be able to detect the particular wavelength of INFRA RED given out by the IR led.It is a special type of diode it t generates current when exposed to light it is connected in reverse bias for IR rays detection. Infrared rays can be of varying wavelengths and can take up any value belonging to their waveband. Just as there can be visible led of different colours, IR led also emit rays of different wavelengths.
The IR led and Photo diode are connected in parallel to each other which will act as transmitter and receiver. In proximity sensor this mechanism is used by the photodiode to generate electrical signal.The principle follow by proximity sensor is very simple. But when the IR rays fall on to it more charge carriers are generated and its resistance decreases and a current starts flowing which is proportional to the intensity of the radiation falling on the photo diode.
