1. Street Light Automation
Automated Street Lighting System will automatically switch the street light ON and OFF based on the amount of sunlight present using the LDR sensor. By this technique power wastage will
get reduced. Key Words: LDR sensor, LED's, Raspberry Pi.
2. IR with Motor
IR with Motor is if any obstacle in front of IR sensor it will detect and motor will be Turn ON. By this technique automatic door open. Key Words: IR Sensor, Relay, 9V Battery, DC Motor.
3. Seven Segment Display
We are going to do Raspberry Pi 7 segment display interfacing. Seven Segment displays are the cheapest for a display unit. A couple of these segments stacked together could be used to display temperature, counter value etc. We will connect the 7 segment display unit to GPIO of PI and control them to display digits accordingly. After that we will write a program in PYTHON for seven segment display to counts from 0-9 and resets itself to zero.
4. Fire Alarm
The embedded systems used to develop this fire alarm system are Raspberry Pi. The key feature of the system is the ability to an alert when a fire is detected. When the presence of smoke is detected, the Buzzer will be ON.
5. Ultrasonic Distance Measurement
Ultrasonic Distance Meter Using Raspberry Pi 3. Ultrasonic ranging module HC-SR04 provides 2cm to 400cm non-contact distance measurement range. Its accuracy can reach ±3mm with a cycle period of 50ms, which is the minimum time delay recommended before measurements are taken.
