ELECTRONIC PROJECT & PRODUCTS
1. Traffic Signals Density project
In this system, we use IR sensor to measure the traffic density. We have to install one IR sensor for each street; These sensors always detect the traffic on that particular road. All these sensors are connected to the microcontroller. Based on these sensors the controller detects the traffic and controls the traffic system.
2. Solar Battery Charger
This is a simple circuit for charging a 6V, 4.5Ah rechargeable lead acid battery from a solar panel. This solar charger has current and voltage regulation and also has overvoltage capability. This circuit can also be used to charge any constant voltage battery as the output voltage is adjustable.
3. Circuit of FM radio
FM radio circuit is a simple circuit that can be tuned locally with the required frequency. This article describes an FM radio circuit. This is a pocket radio circuit.
4. LED Lamp with the help of USB configuration
It is a simple USB LED light circuit that produces an output of 5v. It can be used as an emergency light and also as a reading lamp.
5. Password based door lock system
The system has a password-based door locking system, where after entering the correct code or password, the door opens and the person concerned can enter the secure area. After a while the door closes. For more details read this post completely.
6. Water Level alarm
It is a simple, low cost hardware design that uses a 555 timer circuit. The objective of this project is to perform water level detection with simple and cheap hardware without compromising the performance of the device.
7. Automatic washroom light switch
This is a simple yet very useful circuit in our real life which helps in automatically turning on the light when a person enters the bathroom and automatically turning it off when they exit.
8. Cell phone detector
This is a simple circuit that helps detect the presence of an active cell phone by detecting signals in the frequency range of 0.9 to 3GHz. It helps in monitoring the cell phone which is used for spying.
