In this project he would like to demonstrate, how you can control a LED or anything else,
and get temperature of your room over internet via C# with Arduino UNO and Arduino Ethernet Shiled.
To do this or some like this, you need the following stuffs.
1. Arduino UNO board
2. Arduino Ethernet Shield
3. 1 x LM 335 temperature sensor
4. 1 x 2Kohm resistor
5. some cables
6. 1 x LED
7. RJ45 cable
8. USD cable
LM 335 temperature sensor
As a temperature sensor, the circuit will read the temperature of the surrounding environment and relay this temperature to us back in degrees Kelvin.
The LM335 sensor outputs 10mV/°K. So if the LM335 is giving an output reading of 2.943 (which is 2943mV), then this is equivalent to a temperature of 294.3° Kelvin. All you have to do is take the output reading and divide it by 10 in order to get the temperature output reading. This output reading of 294.3° kelvin is equivalent to 70°F and 21.11°C.
The IC we will use to measure the temperature in this circuit is the LM335 IC. We will integrate this with the arduino to measure the temperature. The arduino will then read this measured value from the LM335 and translate into degrees kelvin, fahrenheit and celsius, which we will be able to read from the computer from the arduino serial monitor.
Components Needed to Build the LM335 Temperature Sensor Circuit
