A UNIQUE SOLUTION FOR HOME AUTOMATION OF THE ELECTRICAL APPLIANCES CONNECTED TO SWITCH BOARDS CAN BE CONTROLLED USING AIR BASED REMOTE CONTROL

in nutshell Pump controller objective is to celebrate the world water day REMOTE CONTROLLER FOR ELECTRICAL APPLIANCE objective is to Upgrading lifestyle.

This board decodes dtmf signal either from an audio source or phone line to 4 bit binary ttl (5v) level output. It also indicates outputs with led.

Heart beat sensor is designed to give digital output of heat beat when a finger is placed on it. When the heart beat detector is working, the beat led flashes in unison with each heart beat. This digital output can be connected to microcontroller directly to measure the beats per minute (bpm) rate. It works on the principle of light ir modulation by blood flow through finger at each pulse.

Microphone with audio amplifier designed for use in low voltage applications. Onboard electret microphone level is amplified to 250 mW level. Designed for use with audio processing by AD of microcontrollers or by software at PC or for analog frontend applications.

Sensor keeps transmitting modulated infrared light and when any object comes near, it is detected by the sensor by monitoring the reflected light from the object. It can be used in robots for obstacle avoidance, for automatic doors, for parking aid devices or for security alarm systems, or contact less tachometer by measuring rpm of rotation objects like fan blades.

Proximity Sensor is used to detect objects and obstacles in front of sensor. Sensor keeps transmitting modulated infrared light and when any object comes near, it is detected by the sensor by monitoring the reflected light from the object. It can be used in robots for obstacle avoidance, for automatic doors, for parking aid devices or for security alarm systems, or contact less tachometer by measuring RPM of rotation objects like fan blades.

The speech recognition system is a completely assembled and easy to use programmable speech recognition circuit. Programmable, in the sense that you train the words (or vocal utterances) you want the circuit to recognize. This board allows you to experiment with many facets of speech recognition technology. It has 8 bit data out which can be interfaced with any microcontroller for further development. Some of interfacing applications which can be made are controlling home appliances, robotics movements, speech assisted technologies, speech to text translation, and many more.
