# LM355 DATASHEET PDF

The model number is a specific version of a generic that can be purchased or sampled. Status Status indicates the current lifecycle of the product. This can be one of 4 stages: Pre-Release: The model has not been released to general production, but samples may be available. Production: The model is currently being produced, and generally available for purchase and sampling. Last Time Buy: The model has been scheduled for obsolescence, but may still be purchased for a limited time.

You can adjust this value to meet your personal preference or program needs.

So to get the degree value in fahrenheit, all that must be done is to take the voltage output and divide it by this give out the datashert degrees in fahrenheit. This translates into the circuit schematic: This allows us to calibrate the temperature sensor if we want a more precise dstasheet readout. In this project, we will demonstrate how to build temperature sensor circuit using a LM sensor.

This is the datasheet of the LM IC: The arduino, with suitable code, can then interpret this measured analog voltage and output to us the temperature in degrees Kelvin, Celsius, and Fahrenheit. We will integrate this with the arduino to measure the temperature. All you have to do is take the output reading and divide it by 10 in order to get the temperature output reading. Since the output pin can give out a maximum of 5 voltsrepresents the full possible range it can satasheet out.

We get the ratio of the raw value to the full span of and then multiply daatasheet by to get the millivolt value. This is because there is millvolts in 5 volts. Pin 2 is the output pin. It is divided by because a span of occupies 5V. Once lm35 have this ratio, we then multiply it by to give the millivolt value. Now the computer is connected to the arduino. Before we can get a Kevlin reading of the temperature, the analog output voltage must first be read.

We can now write code in the processing software to give instructions to the arduino. This is so that we can hook our arduino to a computer and send it code that it can run to display to us the temperature.

Pin 2 gives an output of 1 millivolt per 0. The output pin provides an analog voltage output that is linearly proportional to the fahrenheit temperature. Pin 1 is the Adjustable Pin Adj. Temperature Sensor Circuit The temperature sensor circuit we will build is shown below: Once this analog voltage in millivolts is calculated, we then can find the temperature in kelvin by the equation: So if the LM is giving an output reading of 2.

This output reading of So you circuit connections are: All 3 are calibrated different to output the millivolt voltage reading in proportional to these different units of measurement. Once we obtain this Celsius value, we can convert into Fahrenheit with the following equation: The type B side of the connector goes into the arduino and the type A side into the USB port of the computer.

We can use any type of arduino board. This will be the raw value divided by times As a temperature sensor, the circuit will read the temperature of the surrounding environment and relay this temperature to us back in degrees Kelvin.

All we must do is write this code and upload it to the arduino to convert this kelvin temperature into fahrenheit and celsius.
