With the regional Bluetooth detection method, this study aims to fix the location of pet activities and thus perform temperature and humidity sensing and environmental adjustment, with the goal of achieving remote monitoring. The main body of the whole system is Arduino equipped with temperature and humidity sensors, which upload data collected to the cloud database via a wireless network communication module. The temperature and humidity values are displayed on the mobile APP, so does the location of the monitored object. When the monitored object is approaching, household appliances start running under the control of the relay according to the set temperature and humidity, thereby achieving the constancy of temperature and humidity.
