Internet connected fire/smoke alarm project

Martin Harizanov blogged about his cheap DIY IoT smoke detector:

This project is an upgrade to a previous project of mine – the DIY IoT smoke alarm. It is a more advanced version that uses dedicated hardware rather than the generic “Funky” project + external components. In essence, the module integrates into cheap smoke detectors and provides wireless event transmission plus periodic battery measurements to cloud infrastructure using BBoilRF as a gateway (over MQTT).

More details on Martin’s corner on the web blog. See part 1 here.
