Blood pressure (BP) is one of the vital signs measured in a patient during a medical check-up. Abnormality in BP values is an indication or symptoms in most cardiovascular diseases. Innovations were established in dealing with the measurement of BP for the past years. In this paper, the researcher presented a wearable blood pressure monitoring device with SMS notification. Its design and processes were explained in this paper to further demonstrate the content of research. This paper aimed to determine whether the prototype is reliable enough with a novel approach for blood pressure monitoring purposes. The project is a device worn in a wrist using a microcontroller, battery and a cuff. The patient has a mobile app installed in his/her mobile phone. Information should be entered in the mobile app such as contact number and the normal blood pressure of the patient. The mobile phone is connected in the wearable device through Bluetooth. The user or patient will have to wait 5 minutes before the blood pressure will start measuring. This is to let the patient rest for a while. A beep sound indicates that the device starts measuring. After 10 seconds, the cuff will inflate and another 30 seconds time is intended for the blood pressure measurement. The measured valued is displayed in the mobile app, and then sends SMS only if the patient's BP is higher than normal. Its design is a microcontroller-based project, equipped with a Global Positioning System (GPS) module to be able to locate the user, a Bluetooth module to be able to connect to a smart phone installed with the Blood Pressure Monitoring App. The device was carefully programmed and tested to ensure its workability.

Over the past decades, fire cannot be prevented in our homes and society. Hence, the author came up with an idea to create a robot that will serve as first responder to fire and hazardous chemicals. Problems were identified and objectives were formulated as guides in the establishment "Automated Hazardous Gas Detecting Robot using Wireless Sensor Networks with GSM-SMS Alert and Fire Control System for households". This robot is designed having two wheeled drive navigation to easily move and detect hazardous substances and fires. It is equipped with gas sensor to monitor if there is a gas leakage in a room and is programmed to automatically send messages to the registered number using GSM Module. It was installed to be able to send Short Messaging Service (SMS). This paper is about a microcontroller based project, with microelectronics devices, namely, Flame Sensor (KY-026), GSM Module (SIM 900A), gas sensor (MQ-2), L293D Motor Shield, a 12V DC motor and 12V DC Water Pump, Arduino UNO, a light emitting diode (LED) and a buzzer. These were carefully programmed and patiently tested to ensure its working conditions. Through well-planned design, data gathering and testing its reliability, the author came up with an automated detection system in a robotic application with features like SMS notification, an alarm system and extinguishing fire. The author concluded that this project is reliable and can help the homeowners secure their home from the blazing disaster brought by fire and hazardous gases.
