Exploring the use case for the product was really insightful and a lot of fun. Environmental / HVAC management is one of the biggest sales cases within IoT; intelligent thermostats are in heavy demand. But a thermostat, whether wall based or a TRV, cannot understand a room's full temperature. Thus, it might be hot near a radiator and frigid elsewhere. How do you solve that problem inexpensively? aërQ Temperature and Humidity Sensor. Sized the same as a coin cell battery and Z-Wave enabled, we engineered this to be able to fit just about anywhere (on anything, under anything), and be cheap enough that multiple measurements of a room's temperature, humidity, dew point, and mould potential (massive health issue) can be taken. Great work for which a co-invention patent was awarded today.
