Introduction To monitor electricity consumption of a house I have proposed a light sensor to detect the flashing of the LED on the electricity meter that indicates energy is flowing. In previous blogs I have covered the selection of light sensor and its electrical connection to an Arduino Uno. Now it is time to look… Continue reading Arduino to monitor electricity usage

Sensors to detect LED output on electricity meters.
Many UK houses have electronic meters for measuring electricity consumption. Most of these have an LED that flashes when a given quantity of energy has been consumed. In the UK most meters have LED outputs which flash once for every 1Wh. They will flash 1000 times for each kilo-watt-hour (1 kWh). If a sensor is… Continue reading Sensors to detect LED output on electricity meters.
IOT Devices – to push or to pull?
Introduction There are two methods to collect data from an monitoring device. The device can be asked to provide the data or the device can be programmed to deliver the data without prompting. The situation is similar for control devices. Push or pull? When researching the devices connected to the Internet of Things (IOT) you… Continue reading IOT Devices – to push or to pull?
