Notion Sensors: Ever heard of Notion Sensors..Notion has eight different senses, all working seamlessly together and makes it easy to monitor your entire home, no matter where you are.. It measures 8 Parameters Viz..Temperature, Acceleration, Natural Frequency, Light, Motion, Sound, Angular Rate and Water. In terms of applications it monitors doors opening and closing, can alert on room temperature, detects water leaks in sink, detects alarm from a smoke sensor and much more. Powered by coin cell batteries, these sensors are cordless and plugs in any space in your home. Notion apps are available for iOS and Android that can help in adding any tasks like assigning the sensor to monitor temperature, listen to your door bell, watch out for water leakage etc.. Apart from the sensors you need to have a Bridge that receives the signal from the sensor and sends them to your wi-fi router. Sensors can be about 175 Ft from this Hub/Bridge. Happy Learning.. ...

      In the near future, billions of pieces of equipment will be connected to one another – everything from the yogurt container that reminds you to eat its contents, to the smart city, where data is collected and analyzed in real time so that traffic flows better, water is supplied more efficiently, and resources are used more economically. By 2020, approximately 50 billion objects will be linked together in the internet. The Internet of Things ( IoT ) is the network of physical objects or "things" embedded with electronics, software, sensors and connectivity to enable it to achieve greater value and service by exchanging data with the manufacturer, operator and/or other connected devices. Each thing is uniquely identifiable through its embedded computing system but is able to interoperate within the existing Internet infrastructure. A thing , in the Internet of Things, can be a person with a heart monitor implant, a farm animal with a biochip transponder...

Circuit Breaker A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. Its basic function is to detect a fault condition and interrupt current flow.  Unlike a fuse, which operates once and then must be replaced, a circuit breaker can be reset (either manually or automatically) to resume normal operation.  Circuit breakers are made in varying sizes, from small devices that protect an individual household appliance up to large switchgear designed to protect high voltage circuits feeding an entire city.

What you know about DMMs and clamp meters can make a big difference to your bottom line How well you equip yourself to do your work plays a big role in your success. When it comes to electrical test equipment, are you sure you have the right tools for the job? Digital Multimeter Vs Clamp Meters We often think of a digital multimeter (DMM) as a direct contact instrument and a clamp meter as an inductive instrument. This leads to the erroneous conclusion that the only real difference is the input method. However, a clamp meter is not a DMM with a set of inductive jaws replacing the test leads. They are two distinctly different instruments, each with its own advantages. A DMM is essentially a voltage measuring tool with some current abilities, while a clamp meter is essentially a current-measuring tool with some voltage abilities. The DMM allows you to do electronic work because of its high resolution—it measures in milliunits (for example, millivolts, milliamps and milliohms). It...

Relays A relay is an electrically operated switch. Relays are used where it is necessary to control a circuit by a low-power signal (with complete electrical isolation between control and controlled circuits), or where several circuits must be controlled by one signal.   Many relays use an electromagnet to mechanically operate a switch, but other operating principles are also used, such as solid-state relays A type of relay that can handle the high power required to directly control an electric motor or other loads is called a contactor Solid-state relays control power circuits with no moving parts, instead using a semiconductor device to perform switching.

A contactor is an electrically controlled switch used for switching a power circuit, similar to a relay except with higher current ratings. A contactor is controlled by a circuit which has a much lower power level than the switched circuit. Contactors are used to control electric motors, lighting, heating, capacitor banks, thermal evaporators, and other electrical loads.
