Day in and day out I used them. That is why I started my own site for those that want to legitly get paid. That is much more than bux. Regards, Jake Owner, Lersner. First we describe the LCD we used. There are two kinds of LCD modules. Features of GDM A. Built-in controller S6A or equivalent 3.

Easy interface with 4-bit or 8-bit MPU 6. BKL to be driven by pin1, pin2, or pin15, pin16 or A, K 7. If you use GDMA see this datasheet. The secret of success is approaching by eliminating confusions. If you have confusions then make clear your lcd basics. These links will help you very much. What is a temperature sensor? Temperature sensor is an electronic device which provides a voltage analogue of the temperature of the surface on which it is mounted.

In other ways, an analog temperature sensor is pretty easy to explain, it’s a chip that tells you what the ambient temperature is! These sensors use a solid-state technique to determine the temperature.

That is to say, they don’t use mercury like old thermometersbimetallic strips gdm1602w in some home thermometers or stovesnor do they use thermistors temperature sensitive resistors. Instead, they use the fact as temperature increases, the voltage across a diode increases at a known rate. Technically, this is actually the voltage drop between the base and emitter – the Vbe datasheeet of a transistor.

By precisely amplifying the voltage change, it is easy to generate an analog signal that is directly proportional to temperature. There have been some improvements on the technique but, essentially that is how temperature is measured. Because these sensors have no moving parts, they are precise, never wear out, don’t need calibration, work under many environmental conditions, and are consistent between sensors and readings.

Moreover they are very inexpensive and quite easy to use. Types of temperature Sensors. There are big differences between different kind of temperature sensors. They may be classified into two groups: Contact temperature sensors measure their own temperature.

One infers the temperature of the object to which the sensor is in contact by assuming or knowing that the two are in thermal equilibrium, that is, there is no heat flow between them.

Most commercial and scientific noncontact temperature sensors measure the thermal radiant power of the Infrared or Optical radiation that they receive from a known or calculated area on its surface, or a known or calculated volume within it in those cases where the obect is semitransparent within the measuring wavelength passbad of the sensor.

One then infers the temperature of an object from which the radiant power is assumed to be emitted some may be reflected rather than emitted. Sometimes the inference requires a correction for the spectral emissivity NB: Knowing how and when to apply a spectral emissivity correction is part of the inference, too, and can introduce significant errors if not done correctly.

See our Trip down the E-missivity Trail to help you understand that aspect a little better. Notes The truism that all sensor have errors in their readings – all the time. One key secret to high quality measurement results is to have confidence in the error estimates. Neglecting to make a careful error analysis can result in error much larger than the assumed values.

A figure datasheeet the temperature sensor we used is given below. Suitable for remote applications 6. Low cost due to wafer-level trimming 7.

Operates from 4 to 30 volts 8. Low impedance output, 0.

Others follow your corresponding datasheet. If you are wondering how lm35 works here’s it.

As the temperature increases, the voltage across diode increases at a known rate. As lm35 has diodes inside it happens same there. So what lm35 does is adjusting the output voltage per oC in real. So if lm35 outputs 10mV it means 1 oC.

If it outputs 20mV then it is datashedt oC. We use Atmega32 to do the analog to digital conversion. See the complete pin connection of the circuit in the image below.

If you only want to test the LCD module ignore the lm35 part and respective pin connection. Remember it is a tested code. So you can check gdm102a by writing like this. And you can connect a led to PC0 pin to check if led is lit. If LED is not lit then checkout lcd connections again. After compiling the c code, burn the hex code of your program into your atmega MPU using atmel burning tools.

After programming MPU is done place the it on the circuit. Now connect the power supply. To use this code with atmega16 change this line. In the same way, change to mega8. You can download the whole project code and proteus simulation files which works perfectly for atmega32 from datsaheet. Attaching Temperature Sensor for Displaying Temperature. If you want to know how atmega ADC works follow here.

With codevision you might be in confusion how gdm102a do a simple adc read.

The function to read the analog data is like this one: Assuming this code is in top of your gdm16602a function a simple call to this function will return value for analog input. Some images of the final project has been attached below. Click on the images to view in high resolution.
