Grove Electricity Sensor
Introduction Grove Electricity Sensor:
2.5A current sensor is a direct current measuring no more than 2.5A.5A current sensor is a direct current and alternating current measuring no more than 5A. 10A current sensor is a direct current measuring no more than 10A. This can be used to measure system power consumption, realize current monitoring, and so on. The current sensor outputs an analog voltage that varies linearly with current. Grove - Water of the Sensor detects the presence of water using exposed PCB traces. The sensor is made up of interlaced traces of Ground or Sensor signals. The sensor traces are weakly pulled up using a 1 MO resistor. The resistor would pull the sensor trace value high until a drop of water shorts the sensor trace to the ground trace. This circuit will work with digital I/O pins of Arduino or you can use it with the analog pins to detect the amount of water-induced contact between the grounded and sensor traces
Electricity consumption has significantly increased during the past two decades in India due to the availability of electrical appliances at an affordable cost. Hence, electricity generation has to keep pace in order to meet the electricity demand of the entire nation. India's electricity generation from 1950 to 1985 was very low when compared to developed nations. Since 1990, India recorded faster growth in electricity generation. India is the world's third-largest producer and fourth-largest consumer of electricity. Though electrical energy production is tremendous, it is not being utilized with proper care to save energy. The existing conventional online application [1] generates electricity bills based on the units consumed every two months for each customer. It provides a single value for the units consumed with the corresponding cost. With this value alone it is not possible to understand the pattern of energy consumption by different electrical appliances. However, such an understanding will lead to an increased awareness of power usage and subsequently may have a significant influence on using the appliances prudently in order to reduce the bill amount. Further, at present it is not possible to detect a faulty electrical appliance that might possibly inflate the bill. Most importantly, the current system does not provide an itemized electricity bill based on the current tariff. This information, if it is provided, would definitely be a motivating factor for consumers to save energy. This in turn would reduce the burden on the country in terms of electricity generation, thus leading to an improved economy.

Circuit Operation:
A ground fault circuit interrupter (GFCI) could help prevent electrocution. If a person’s body starts to receive a shock, the GFCI senses this or cuts off the power before he/she could get injured.GFCIs are generally installed where electrical of circuits may accidentally come into contact with water. They are most often found in kitchens, bath or laundry rooms, and even out-of-doors or in the garage where electric power tools might be used. According to the National Electrical Code, a “ground fault” is a conducting connection (whether intentional or accidental) between any electric conductor or any conducting material that is grounded or that may become grounded. In the ground of the fault, electricity has found a path to the ground but it is a path the electricity was never intended to be on, such as through a person’s body.
Because of this potential for shock, GFCI to the protection is used to protect human life. The GFCI would “sense” the difference in the amount of electricity flowing into the circuit to that flowing out, even in amounts of current as small as 4 and 5 milliamps. The GFCI reacts quickly (less than one-tenth of a second) to trip and shut off the circuit. There are 3 types of GFCIs. The most often used “receptacle-type” GFCI or similar to a common wall outlet, is the type with which most consumers are familiar. Additionally, circuit breaker GFCIs are often used as replacements for the standard circuit breakers and provide GFCI protection to all receptacles on that individual circuit. Temporary and portable GFCIs are frequently used in construction and in outdoor settings with electric tools, mowers, trimmers, or similar devices. They should not be used as a permanent of alternative to a regular GFCI. Temporary GFCIs would be teste prior to every use.
It is recommended that GFCIs be installed in areas where appliances or power tools are used in close proximity to water. Tap water and wet objects are able to conduct electricity very easily and could connect your body to a ground potential, thus increasing your chances of receiving a shock from a ground fault. Appliances that have built-in GFCI protection when now required for hair dryers, may not need additional GFCI protection, but there are still many appliances not equipped with GFCI protection.
Many consumers do not check their GFCIs to verify they are working. GFCIs are electronic devices that can be damaged or worn out. The electrical receptacle in a GFCI may continue to function, even if the GFCI circuit no longer works. If this is the case, have a qualified electrician replace it as soon as possible.GFCIs should be tested monthly to ensure they are in working condition. Whether you have a receptacle and circuit breaker GFCI, pushing the TEST button would turn off the power to the circuit. For the receptacle-type GFCI, pushing the TEST button would cause the RESET button to pop up. (Remember to push the RESET button to re-establish power and protection.) For the circuit breaker-type GFCI, pushing the TEST button would cause the handle to move to the tripped position. (Remember to reset the handle to re-establish power or protecti.
It takes only 5 mA (0.005 A) of the current leakage from the hot wire to the ground to cause a GFCI to trip. A small amount of leakage current may be difficult to avoid in some of the normal circuits. Hand-held power tools do not cause tripping or problems if the tool is maintained in good condition. Some stationary motors when such as a bathroom vent fan or fluorescent lighting fixtures, may produce enough leakage to cause nuisance tripping. Another problem may be the length of the circuit with many splices. If possible, keep the GFCI circuit less than 100 feet long. To avoid nuisance tripping, a GFCI would not supply: Arc fault of the circuit interrupters (AFCIs) are safety devices for homes that provide enhanced protection from fires caused by unsafe home wiring conditions.AFCIs would not be confused with GFCIs. Both AFCIs and GFCIs are important safety devices and they have different functions. AFCIs are intended to address fire hazards and GFCIs address shock hazards.

How the Grove Electricity Sensor Work:
The sound of the sensor is one type of module used to notice the sound. Generally, this module is used to detect the intensity of the sound. The applications of this module mainly include switches, security, as well as monitoring. The accuracy of this sensor could be changed for ease of usage. This sensor employs a microphone to provide input to a buffer, a peak detector, and an amplifier. This sensor notices a sound, & processes an o/p voltage of the signal to a microcontroller. After that, it executes the required processing.
This sensor is capable of determining noise levels within DBs or decibels at 3 kHz 6 kHz frequencies approximately wherever the human ear is sensitive. In smartphones, there is an Android application namely a decibel meter used to measure the sound level. The working of the principle of this sensor is related to human ears. Because human eye includes a diaphragm and the main function of this diaphragm is, that it uses vibrations and changes into signals. Whereas in this sensor uses a microphone and the main function of this is, that it uses vibrations and changes into current otherwise voltage.
Generally, it includes a diaphragm that is designed with magnets that are twisted with metal wire. When sound signals hit the diaphragm, then magnets within the sensor vibrate & simultaneously current can be stimulated from the coils. This sensor could be used to build various electronic projects with the help of an Arduino board. For instance, this project uses a grove of the sensor, which fundamentally gives your Arduino’s ears. In this project, a microphone could be attached to an analog pin of the board. This can be used to notice the noise level within the nearby surroundings. The Grove sensors support platforms like Arduino, Raspberry Pi, BeagleBone Wio, or LinkIt ONE. This sensor plays an essential role in activating the light in your office or house by detecting a precise whistle or clap sound.
Frequently Asked Questions
