In this research the concept of a burglar alarm system is currently used mainly blaring alarm when an intruder but with todays busy society the voice of alarm no interest or some car owners might not hear the sound of the signal due to the car park. The thieves take the opportunity to have success car theft with mobile messaging technology that costs less and is very active in the daily life of common people. Therefore the development of vehicle theft alarm system with short messages via mobile phone to improve the performance of the car alarm system can send a short message to the mobile phone owner immediately. The motion sensor device that is installed in the vehicle to detect theft or intrusion cars. Invasive test methods such as smashed glass opening the car door. Reaching into the car or inside the front of the car. The system can detect all. It sends messages to the phones owner and the owner of the car did not turn off the car or by calling into the system and then hang up. The system sends a message to every one minute

This paper presents the development of Automatic Malfunction Warning System (AMWS). The objective is to improve the performance of 5-kWp Grid-connected PV system with real time PC based monitoring system installed at Rajamangala University of Technology Suvarnabhumi Nonthaburi Thailand. The system is able to measure electrical parameters and air condition with real-time display. The AMWS comprises of hardware and software. The software was developed by LabVIEW. The AMWSs function is to monitor important equipment in the PV energy system. If there is a malfunction or any detected faults the AMWS would directly warn the operator of the PV energy system instantly. Results showed that the AMWS can complete programmed operation according to specified condition. The AMWS can send the right details and the cause of malfunction by SMS and E-mail every time the system did not work properly. The benefit of this system is that the operator can get the system to run properly and fix problems in a short period of time

This article presents a design and development of a low rate wireless sensor network coordinator controller. Wireless sensor networks are cheap and comprised of a small fully autonomous processing communication and sensing devices. In this study develops the system for monitoring and flood warning. This research used small embedded micro controller. The system can expand into multi network and work with single processor. This design will reduce components and power assumption. The research use Propeller Chip by Parrallax Inc. This chip contains eight processors inside. All eight processors can perform tasks simultaneously or with coordination from other processors. A designed of system works together with wireless sensor networks. The first step of the experiment is creating main node and sub node in flooding area and finds transmission of data between them. Experimental results show that we can use single microcontroller work with multi-network. It can monitor result of network directly from Propeller chip by generating computer monitor signal.

This paper presents the development of a low rate and low power consumption wireless sensor network. Wireless sensor networks are cheap and comprised of a small fully autonomous processing communication and sensing devices. The purpose of this study is to develop the system for monitoring and flood warning. They will work with wireless sensor network (WSN) system. WSN has been restricted power supply communication distance and low computing power. But they will work with network in vast area send and receive raw data from each sensor node. It has the ability to cooperatively collect data and retransmit in order to process or alert. The first step of the experiment is creating main node and sub node in flooding area and finds transmission of data between them. When sensor node is not receiving or transmitting data the module can be switched into the sleep mode low power consumption mode
