Pull-up resistors are used in electronic logic circuits to ensure that inputs to logic systems settle at expected logic levels, if external devices are disconnected or high-impedance is introduced. They may also be used at the interface between two different types of logic devices, possibly operating at different power supply voltages.A pull-up resistor weakly "pulls" the voltage of the wire it is connected to towards its voltage source level when the other components on the line are inactive.

Android mobile phone application developed in order to extended data communication range of our wireless health monitoring device..

Patient monitoring systems are gaining their importance as the fast-growing global elderly population increases demands for caretaking. These systems use wireless technologies to transmit vital signs for medical evaluation. The aim of the project is to provide a better health care to people from house in more economic and pertinent friendly manner. The need of home based health monitoring system is increased now days because health care cost is increasing exponentially in last few decades. In the proposed home based health monitoring system using android smart phone includes the aspects of acquisition of medical parameters like Body temperature and Pulse rate.

The board has two relay driven by TTL circuit . The board works on 5V but the input signal can come directly from controller output working at 3.3V or 5V to control relays. Each relay can switch varierty of AC or DC high voltage, high current loads working at 110V or 220V AC mains like lights, fans, motors and such. The status of relay is indicated by individual LEDs.

Automatic Meter Reading DIY Kit- UNO ATMEGA328

Automatic meter reading, or AMR, is the technology of automatically collecting consumption, diagnostic, and status data from energy metering devices (electric) and transferring that data to a central database for billing, troubleshooting, and analyzing. This technology mainly saves utility providers the expense of periodic trips to each physical location to read a meter. Another advantage is that billing can be based on near real-time consumption rather than on estimates based on past or predicted consumption. 

Control anything anywhere any time. Save power. Eliminate service calls. Switch routers, servers, lighting, even industrial machinery via the web and App. Customize the web server with your own using RDL IoT SDK. Each relay can switch AC or DC high voltage, high current loads working at 110V or 220V AC mains like lights, fans, motors and any electrical equipment.
