The board has only one SSR driven by TTL circuit . The board works on 12V but the input signal can come directly from microcontroller output working at 5V to control SSR. Each SSR can switch varierty of AC or DC high voltage, high current loads working at 110V or 220V AC mains like lights, fans, motors and such. The status of SSR is indicated by LED.

The LM35 series are precision integrated-circuit temperature sensors, whose output voltage is linearly proportional to the Celsius (Centigrade) temperature. The LM35 thus has an advantage over linear temperature sensors calibrated in ° Kelvin, as the user is not required to subtract a large constant voltage from its output to obtain convenient Centigrade scaling. The LM35's low output impedance, linear output, and precise inherent calibration make interfacing to readout or control circuitry especially easy.

At the heart of this technology, a new generation of high-brightness light-emitting diodes. Very simply, if the LED is ON, user can transmit a digital string of 1, if it’s OFF then user can transmit a string of 0. It canbe switched ON and OFF very quickly, which gives instant opportunity for transmitting data. It is possible to encode data in the light by varying the rate at which the LEDs flicker ON and OFF to pass differentstrings of 1s and 0s. The modulation is so fast that the human eye doesn’t notice. There are over 14 billion light bulbs used across the world, which needs to be replaced with LEDs ones that transmit data.
