The smart sensor/alarm is a wifi, cloud-based temperature and relative humidity (RH) live viewer with an internal sensor. All settings can be set through the IOS or Andriod application and sends push notifications and text messages as soon as any parameter goes wrong. This model is appropriate for general applications from monitoring homes, retail store freezers, storage facilities or green houses. This device can be paired with our universal AC remote to say turn it on when a room reaches above or below a temperature.
