Air source heat pumps are becoming a popular method for heating and cooling a home. They can provide targeted heat or air conditioning to individual rooms, resulting in energy savings and therefore a lower energy bill. On the exterior of the house is the heat pump condenser, which circulates either hot or cold refrigerant depending on the mode you are using. Inside the condenser is a fan. If that fan were to stop working, or work sub-optimally, the heating and cooling efficiency of the heat pump would suffer (or not work!). Wouldn't it be cool (see what we did there?) to know if it were about to fail so you could have it serviced before it breaks? Well, with Edge Impulse and Arduino hardware, now you can!
