DIY Temperature, Humidity, & Smoke Detector Alarm System Based on Arduino

NewImage

ICStation created a full tutorial on an Arduino based temperature, humidity, and smoke alarm system. Via Instructables

ICStation team introduce you how to DIY this temperature﹠ humidity ﹠smoke alarm system based on ICStation Mega 2560 compatible with Arduino.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 connect to the power supply, after the initialization of hardware, the1602 LCDwill display the current temperature,humidity and smoke volume

2.When we press the NO.1 key, the1602 LCD will turn the page and enter the dangerous temperature setting page.At this time, press NO.2 key once, the dangerous temperature will add one. If the actual temperature is higher than the setting value, the gree LED will light, at the same time the buzzer will alarm. When the actual temperature is lower than the dangerous temperature, the LED will go out and the buzzer will stop alarm.

3.When the 1602LCD display stays on the second page , we press the NO.1 key, you will see the 1602LCD will turn page to the third page and enter the dangerous humidity setting page.At this time, press the NO.3 key, the dangerous humidity will add one.If the actual humidity is higher than the setting value, the red LED will light,at the same time the buzzer alarms. When the actual humidity is lower than the dangerous humidity, the LED will go out and buzzer stop alarming.
