This is to present you a simple and cost-efficient obstacle detecting Circuit. The system was implemented in C++ type Arduino coding Software. Inputting the data and processing it in Arduino; all were digitally maintained; the digital pins of Arduino were used. And the outputs were controlled by the Arduino which were pre-given. This simple, cost efficient and mostly accurate project can be used in farming as well as defense and security sector of any country. Components Required Arduino NANO or Uno (any version) HC-SR04 Ultrasonic Sensor Battery LED Chassis Jumper Wires Circuit Diagram Circuit Diagram UItrasonic Sensor Ultrasonic sensor working Ultrasonic sensors also known as Sonar sensors have been in use for decades. They were once used for mapping of ships in sea and detection of broken/faulty parts in mechanical systems. The ultrasonic sensor works by transmitting ultrasonic waves and these waves strike with obstacles placed in front of the transmitter. The waves are reflected an...

DHT11 is a Humidity and Temperature Sensor, which generates calibrated digital output. DHT11 can be interface with any microcontroller like Arduino, Raspberry Pi, etc. and get instantaneous results. DHT11 is a low cost humidity and temperature sensor which provides high reliability and long term stability. In this project, we will build a small circuit to interface Arduino with DHT11 Temperature and Humidity Sensor. One of the main applications of connecting DTH11 sensor with Arduino is weather monitoring. We have already seen about humidity, relative humidity, humidity sensors and their types in this article.

Circuit Diagram Knock sensor is an essential component and it is used in automobiles. This sensor is located in the minor engine block, head of the cylinder. This sensor is mainly designed to generate the voltage signal depending upon the vibrations which are occurred due to the explosion. When we observe or hear a knock or ping sound along with the noise of an engine in cars is pre-ignition. This ignition can be occurred due to the air mixture or pocket of fuel ignited in front of the flame from the flash plug. So there will be a small shock wave can be occurred around the ignition, which can increase the pressure within the cylinder. In some cases, this can damage the engine. What is a Knock Sensor ? The knock sensor is one kind of sensor used to detect the flash knock. This flash is the state within the engine of the automobile where the fuel starts burning because of the pre-ignition, detonation, otherwise pinging. The main function of this sensor is to monitor the ignition process...
