Dr Lucy Rogers<\/a> has taken inspiration from IBM’s IoT HQ and created an ambient air quality sensor that works using MQTT messages through the IBM Watson IoT Quickstart Platform<\/a>. Readings of the air are taken using a Raspberry Pi Zero and a Rehau USB stick ambient air sensor<\/a>\u00a0and then transmitted through Watson to a DIY GlowOrb made out of a Wemos D1 board. The orb glows green if the air quality is ‘good’ and red if the air quality is ‘bad’ (this is just based on the numerical value returned from the sensor). Instructions and code are available on IBM’s Internet of Things blog<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
