To detect the poisonous gases such as LPG, i- Butane, Propane, Alcohol, etc… MQ-2 gas sensor is used. The rain sensor is used for weather monitoring. To detect flame and the ordinary light Flame sensor is used. PIR sensor is used to detect motion from humans and pets. Touch screen ...
Fig. 8.2 shows the block diagram of the proposed robot. The diagram shows that various information like flame, smoke, temperature, and obstacle objects in and around the fire accident zone is sensed by the flame sensor, smoke sensor, temperature sensor, and ultrasonic sensor, respectively. The ...
Use this ultrasonic sensor setup to do things like tell if a garage door is closed, or if there is a car in a spot. Basically, anything you can sense with a distance sensor. The sensor is reading the distance from the sensor to the object in front of the sensor. It then sends that...
