DIY Temperature & Humidity & Smoke Detector Alarm System

The working voltage of this system is DC5V. It can measure the current temperature, humidity and smoke. It can display real-time data by the 1602 LCD and can realize the sound and light alarm when in the dangerous temperature and humidity. It is a simply and easily to operate monitoring alarm system about temperature humidity and smoke. Functions 1. When connected to the power supply, after the initializati ...

Smoke Detector using MQ2 Gas Sensor and Arduino

Smoke Detectors are very useful in detecting smoke or fire in buildings, and so are the important safety parameters. In this DIY session, we are going to build a Smoke Detector Circuit which not only sense the smoke in the air but also reads and displays the level of Smoke in the Air in PPM (parts per million). This circuit triggers the Buzzer when Smoke level becomes higher than 1000 ppm, this threshold va ...

Photoelectric Smoke Detector

Smoke detector is a device incorporated on fire alarm system; it is usually installed on buildings to alarm the occupants when there is a fire (when there’s smoke, there’s fire). This provides the crucial early warning to escape injury or death in fire. This project uses optical method design; the sensing part is the photo chamber that is composed of infrared light source and a photoelectric receiver (photo ...

New Battery Smarts-up your Smoke Detector

In a serious case of out-of-the-box thinking, a design team at Roost in Sunnyvale California have come up with a method to add Wi-Fi connectivity to your old smoke or carbon monoxide alarm by just swapping batteries. Your smoke detector uses a 9 V PP3-type battery right? The new Roost battery contains 9 V lithium cells together with a processor and Wi-Fi chip in the standard PP3-sized battery outline. It mo ...
