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

Connect light sensor (TSL251) to Arduino Uno
Introduction I wanted to monitor my electricity usage. The house has an electronic meter with a flashing LED so the task becomes one of detecting the flashes from the LED and counting them. The selection of sensor is explained in Sensors to detect LED output on electricity meters. Meter to Arduino The electricity meter and… Continue reading Connect light sensor (TSL251) to Arduino Uno
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?
