IDEAL home monitor
For the IDEAL research project on energy usage feedback I have developed a custom sensor platform for long-term wireless monitoring of temperature, humidity, light levels, pipe temperatures and gas and electricity consumption. The IDEAL sensor needs to operate for in excess of 3 years without change of battery. The sensor uses a custom ADC front-end for extremely low power electricity consumption using a split-core current transformer.
I have developed a custom ultra-lower-power radio protocol to enable regular readings of all the sensor quantities for the 3-year lifetime of the sensor, and a custom receiver connected to a Raspberry Pi to upload the collected data to the project's server.
