Bluetooth temperature and humidity sensor is a smart home product designed by Shengrun Technology, which is mainly used for real-time detection and recording Environmental temperature and humidity, display current and historical data through the Magic Wisdom APP, and control other devices through network linkage Prepare.
Normally monitor the temperature and humidity data (5s / time) regularly, Bluetooth radio data (5s / time) regularly, the blue indicator light flashes slowly (10s / time), you can view the recorded temperature and humidity changes through the gateway.
When the temperature or humidity exceeds the set value, the red light flashes quickly (1s / time).
Press and hold the button for 2 seconds to enter the state of fast Bluetooth broadcasting, at this time you can connect, update the configuration or OAD upgrade.
