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 ...
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 ...
This Arduino sensor can be used as a security sensor for detecting intrusion, or as part of the home automation system to sense when a room is occupied. The idea is to use your smart phone to enable the alarm notification when you're out of the house. Then, if the sensor gets tripped...
