This project presents the implementation of a water meter based on ST microcontroller STM32F103. This project allows you to take into account the resources used and transfer data to the user's phone or website via the GPRS or Bluetooth channel. It is also possible to implement Bluetooth data exchange between the device and the user's smartphone and using the LoRa network for integration into the s...
A smart power saving in line power switch designed to remove mains power from a TV or other device in standby to reduce electric cost.
This design uses any infra-red controller with a 36 - 38kHz carrier. A long press of any IR button on the users remote controll will cut the mains power, a short press on any button will restore the mains power.
An override button is also on the power switch to s...
Uses 328PU to turn off light or turn on as needed, Using much software. But it has micro wave detection, pir detection, audio detection, and light detection.
