Can You Control Your Appliances with Just a Bluetooth-Enabled Cell Phone?

AI Thread Summary
Controlling electric appliances directly with a Bluetooth-enabled cell phone is technically feasible, as Bluetooth is designed for wireless personal area networks (WPAN). However, most appliances lack built-in Bluetooth transceivers, making direct control challenging. Implementing Bluetooth technology in existing appliances would incur significant costs. The discussion highlights the limitations of current technology and the economic implications of retrofitting appliances. Overall, while possible, the practicality of this solution is questionable.

Is it possible to remote control electric appliances directly using a bluetooth enabled cell phone (without PC and laptops as intermediate)?
 
Engineering news on Phys.org
Bluetooth is WPAN, which is meant for PC based communications in general.
Such systems based on bluetooth have their own bluetooth controllers ( transceivers).
Implementing this system into general electrical appliances will prove to be expensive.
 
Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...
I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...
I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
