Description

According Circuitstoday blog mentioned that this tutorial we are going to control a robot driven by two DC motors by simply using hand movements. There are different kind of sensors to detect your hand movement like flux sensors, Accelerometers and other gravity based sensors. So for wireless transmission we are going to use RF 434 module which transmit 4 bit data. 4 bit data means you can transmit 16 different combinations i.e., 0000 to 1111. Further in this tutorial we will use an encoder and decoder to avoid interference in the air interface. A motor driver will drive the motors from using the decoder data.

We use our Raspberry pi at the transmitter end to analyze the sensor data and to transmit a data combination to the motor driver to drive the motors accordingly so that the robot can hover around. We will be using a 12 V battery on robot to power the decoder module, receiver module and the motors. At the transmitter end sensors and transmitter encoder module is powered by raspberry pi itself.

Description

The electronic circuit design like in Figure 1 above show you RF based home automation circuit using 8051 IC. 

According Electronicshub blog mentioned that the main component of the RF based Home Automation is the RF Module. An RF Module is a small electronic circuit which is used to transmit or receive data wirelessly.

RF Modules are often used in consumer applications where you need to remotely control some machines or appliances without making any physical contact with them.

Some of the common applications are wireless alarm systems, garage door openers, industrial remote controls, wireless home automation systems and smart sensor applications.

RF modules do not require line-of-sight operation. Hence, they are often used instead of infrared remote controls.
Depending upon the type of application, the RF module is chosen.

For example, in case of short range wireless control applications, we can use ASK modulated RF Module of frequency 315 MHz or 433 MHz.

Description

The electronic projects like in Figure 1 above show you auto intensity control of street lights based on 8051 microcontroller. A microcontroller of 8051 family is used to control the intensity by developing pulse width modulated signals that drives a MOSFET to switch the LEDs accordingly to achieve desired operation.

In the present system, mostly the lighting up of highways is done through High Intensity Discharge lamps (HID), whose energy consumption is high. Its intensity cannot be controlled according to the requirement so there is a need to switch on to an alternative method of lighting system i.e., by using LEDs. This system is build to overcome the present day drawbacks of HID lamps. This system demonstrates the usage of the LEDs (light emitting diodes) as the light source and its variable intensity control, according to the requirement. LED consumes less power and its life time is more, as compared to the conventional HID lamps. The more important and interesting feature is its intensity can be controlled according to the requirement during non peak hours which is not feasible in HID lamps.

A cluster of LEDs are used to form a street light. The microcontroller contains programmable instructions which controls the intensity of lights based on the PWM (Pulse width modulation) signals generated. The intensity of lights are kept high during the peak hours, as the traffic on the roads tend to decrease slowly in the late nights, the intensity also decreases progressively till morning. Finally it completely shuts down at morning 6, and again resumes at 6pm in the evening. The process is repeated.
