Use of LM35 with Arduino and LabVIEW

-

LM35 + Arduino +LabVIEW


I have the following link for the LM35 datasheet so you can check the pin assignment.
Datasheet LM35

Connection from Arduino to LM35

1) LM35 Vout to Arduino Analog port (For example A0)
(You need to change the wire to A0 in the following connection or you can change pin number in LabVIEW)

2) LM35 Gnd to Arduino Ground

3) LM35 Vcc to Arduino 5V



Now connect the Arduino to PC and open LabVIEW.

I have the LabVIEW code as follow:


My room Temperature was around 23 °C but as you touch the LM35 the temperature will rise as you will see in WaveChart. 

As I touched the LM35 the temperature rises.

What is LDR and how it works with circuit to try on?

  LDR ( Light-dependent resistor) A photo-resistor (or light-dependent resistor, LDR, or photo-conductive cell) is a light-controlled variable resistor. The resistance of a photo-resistor decreases with increasing incident light intensity; in other words, it exhibits photoconductivity. [1] In the dark, their resistance is very high, sometimes up to 1MΩ, but when the LDR the sensor is exposed to light, the resistance drops dramatically, even down to a few ohms, depending on the light intensity. LDRs have a sensitivity that varies with the wavelength of the light applied and are nonlinear devices. For example it can be used to turn on a light when the LDR is in darkness or to turn o­ a light when the LDR is in light. It can also work the other way around so when the LDR is in the light it turns on the circuit and when it’s in darkness the resistance increases and disrupts the circuit. How it Works? The way an LDR works is that they are made of many semi-conductive materials wit

Use of 4 Strain Gauge Sensors and LabView DAQ to Measure and Calculate Weigth

We use a weight scale to measure weight but have you wondered how it works?  This article will explain and help you create your own weight-measuring device.  Lets learning begin. Strain Gauge The resistance strain gauge is a resistive element that changes in length hence resistance, as the force is applied to the base on which it is mounted causing stretching or compression. Strain gage is low-impedance devices; they require significant excitation power to obtain reasonable levels of output voltages. A strain gauge can be used to measure the force, where four strain gauges are used, two on the top side, and two on the bottom side. The gages are connected in an all-element bridge configuration, which gives maximum sensitivity and is inherently linear. When the pressure is applied to the plate, two gauge elements of the bridge are subjected to tension; the other two elements are subjected to compression. The corresponding changes in resistance are a measure of the incident pressure. Th
