BackgroundOfTheStudyMicrocontrolled appliance Utilization, Motiondetecting and Humidity Adapting Device

Temperature and humidity sensors such as DHT11 are said to be an efficient and inexpensive temperature monitoring material which is commonly used for conducting a cost efficient and reliable research. Because of this, most devices that is somehow related to the change in environmental temperature are using this type of material.

Different types of motion sensors are widely available in the market, but the most reliable type that we can use in creating a motion dependent device is a PIR motion sensor which is also less expensive and efficient.

RecommendationMicrocontrolled appliance Utilization, Motiondetecting and Humidity Adapting Device

For improvement of the device, we could recommend to adjust the ampere capacity of the fuse used for the device to be able to handle high powered devices. We could also suggest to link the device to something that could be able to block unnecessary load being used by the adapter while it is on standby mode in that case it could eliminate all the phantom loads. Also, further studies could maximize the functions of the wireless data transfer. Add grounding to the outlet of the adapter for additional safety purpose also we could recommend to make the outlet design universal so that any device of different kind of plug can use it too.
