This fire system will use Arduino Nano as a microcontroller and the wireless nRF24L01 as communication data. this system has 2 microcontrollers that have different functions. The first microcontroller will be u
In this article,we are going to build aFire Alarm Systemusing Arduino, LM35 Temperature Sensor and GSM Module. The objectives of thisfire detectorusing arduino is to sense the surroundings for occurrence of fire with help of LM35 temperature sensor, and send 3 SMS alerts to two mobile numbers ...
A Sensor-Node was based of an Arduino and used sensors were of-the-shelf CO-Sensors, Smoke Detector, Temperature Sensors and a RFM95 Transceiver module. The communication protocol was based on the RFM95 module with modifications to suit the specific requirements of the fire alarm system. Each...
The infrared fire detector sends sound and light early warning immediately after the disaster. Then, the intelligent construction platform analyzes and identifies the disaster data, forms instructions, directly transmits them to the command center for comprehensive evaluation of the disaster situation, ...
For example, according to NFPA 72, the National Fire Alarm and Signaling Code, the recommended spacing between smoke detectors in rooms with smooth ceilings up to 3 meters high can be up to 9 meters, with adjustments based on the sensitivity and type of detector used [31]. In contrast, ...
Detection of CO, flame light, and temperature with CNT is described to fabricate a fire detection sensor [86]. Despite the fact that some improvements should be performed in the CNTs, their use as fire detector sensors connected to IoT will be carried out very soon. Vijóvic et al. present...
Using a robot with a metal detector which can sense the presence of conductive elements like land mines and alarm the user. Before going further into details about the second type – i.e. the robot with a metal detector, let us have a brief recall of the two important terms – Land Min...

The adopted wireless temperature sensor consists of four main components: ESP8266 NodeMCU, Type K thermocouple, MAX6675 converter module, and Lithium-ion battery, as shown in Fig. 9. The ESP8266 can be programmed to connect to the Wi-Fi network using Arduino code in Arduino Integrated ...
Forest fire detector constitute of Arduino Uno, LoRa modules, DHT 11 humidity and temperature sensor and the MQ2 sensor. We put several nodes within a forest. In this case of forest fire alarm, the best LoRa configurations are BW 250 CR 4/5 SF 10. Using these configuration, we can send...
