This ATmega168-based project monitors household power usage and logs it to an SD card. Signals from voltage and current detectors amplified LMC6484AIN quad op-amp and then AVR microcontroller computes the power consumption using the formula P=VxI.
The aim of the project is to build PIC32-based bathroom utilities management system. It will control and monitoring water and electricity usage to help user save money on utility bills. The system will turn off lights when not in use and limit water usage. The PIR sensor is used to detect when someone enters [...]
The WatchDuck is an accelerometer-based low cost wireless pool alarm. It will give an alert when a child or an object fell into water. All operation in this project is controlled by PIC 18F23K20 microcontroller. The alarm is composed of two parts: the detector and the base station. The detector is using an accelerometer module [...]
This battery-powered water level monitoring uses PIC12F683 as main processor. The project works in the sleep mode to reduce power consumption. Each 2 second, the watchdog timer will wake-up the MCU and then check the sensor probes condition. If the sensor probes submersed in the water it will generate sound Beep and then go to [...]
