Description:
SMS based Fire detection system using Smoke and Temperature sensor has application in many areas like Industries, Companies, Offices, Shopping malls and even at our home. This project has a Smoke sensor and a Temperature sensor to detect the fire. Fire detection system sends SMS to user when any one these sensor crosses threshold value. We have provided a Buzzer which turns on when SMS is sent to user.

Description in detail:
Various important blocks of system are:
1) Smoke sensor
2) Temperature sensor
3) Analog to digital c ....etc

This home smoke detector circuit warns the user against fire.
It is based on the smoke that is produced in the event of a fire and runs between the bulb and the range of light, the amount of light falling on the LDR is reduced. This type of circuit is called an optical smoke detector. Do not use it as a home smoke detector is the law for electronic projects.

This causes resistance to LDR to enlarge and voltage on the base of the transistor is pulled high the power directly to the COB (chip-on-board) has been completed. the sensitivity of the s ....etc

Android controlled robot project make use of an Android mobile phone for robotic control with the help of Bluetooth technology. This is a simple robotics projects using microcontroller. We have already seen Mobile Controlled Robot using DTMF technology which uses call based method to control robot. Also many wireless-controlled robots use RF modules. The control commands available are more than RF modules. Smartphone controlled robot is superior than all these robots.

This project is a Bluetooth controlled robot. For this the android mobile ....etc
