To make a fire alarm using microcontroller such that the system should also sense the environmental temp, and the user gives it a temprature value as a barrier , and when the environmental temp exceedes that barrier the alarm should be switched on.The useof microcontroller is must. bcz it
hi, i have a experience of the above situation. the project was a building fire alarm system which has a master control unit at the ground and 6 to 7 floor control unit. the communication was bidirectional. they all connected via just 2 wires. i used rs485 and at89c52. the communication is mode 3 serial communication(interrupt driv
There are many type of security system are available in markets. Home security Door lock system Thumb based lock system image processing based security system fire alarm system etc
I've also seen a lot of Freescale (formerly Motorola) 68HC08 and 68HC16 microcontrollers on fire alarm control panels ...
Daylight and even more incandescent lamp light has a considerable IR content. So an IR measurement is very unspecific. Far UV sensors are more specific and have been used as flame detector in furnaces as well as for fire alarm. They are particularly good for distance sensing where an optical or ionization smoke detector doesn't work.
I want to isolate the ground within my fire alarm system so that the detectors ground will be isolate with the PIC ground since these detectors used 24Vdc and PIC required 5Vdc. I think ground isolation would reduce the fault within system.
Guys, i and my friend are going to do a fire and Smoke alarm. I have the circuit for the alarms, but what we want to do is that when the alarm is triggered, we want to call a mobile phone so as to tell that there is a smoke or fire in the house. So, could you people help us to make a circuit that can do (...)
Dear all, I am doing a fire alarm controller panel. In that i want to do, if there is any event comes, then we need to dial mobile or telephone number automatically. Is it possible with 8051 microcontroller with GSM or CDMA module. If possible means pls give me the GSM and CDMA module spec and how to interface to 8051. Thanks, (...)
Hi... I am working on a project where I need to interface a fire sensor. I have searched on google about the fire sensor modules, but all I got is the module which gives alarm on detecting fire. However, I want a module which just detects fire and gives output in the form of current or voltage which (...)
Well each of the safety circuit you mentioned would require different designing. For eg. For Designing a fire safety system you can have following prototype : 1. Temperature sensor interfaced to 8052 microcontroller and then program it to take appropiate action thereafter. check : 2.
Hi, I need to check the status of 12 events of infrared barriers sensors. This must be in "real time" and all of them can appear at the some time. Then, I'll fire an alarm if the amount of events is less than a "X" number in a second. What is the better manner to solve it? note: the input signal is a 5v pulse and it occurs when somebody

Hello, I am new to mikroc and i have a project to detect intrusion and fire and send alarm through gsm to any number i did that but for temperature sensor if it is higher than a 28 for example it sends an alarm message but whenever it is at this temperature or above it keeps sending the message forever many times i need it to detect high (...)
I have a pic16f887 microcontroller and four types of sensors (temperature sensor , smoke sensor, ping, and motion sensor) connected to it to detect intrusion and fire i need to detect any incident and send at command to the gsm to call the police and play a recorded voice to alarm for the incident ... i know how to place a call and how to (...)
Dear Friends, I want ckt should detect the smoke, and fire a alarm, also it should send an immediate sms to the security so that if he is not their then also it is possible to go their, actually it is very important company, where important files or money is their... I want it to interface with 89C51, detector yet not decide, please suggest m
