·Connect temperature and humidity sensors, water level, liquid level meter, etc.
·Connect analog signal sensors, current, voltage transmitters, etc.
·Remote control of water pumps, motors, power supplies, relays, etc.
·Connect human body sensor, smoke sensor, water sensor and other sensors
·Other instruments

 

Smart Meter Reading


Traditional manual meter reading is time-consuming and laborious, and accuracy and timeliness cannot be reliably guaranteed. This leads to the failure of relevant marketing and business management software to obtain sufficiently detailed and accurate original data; general manual meter reading is performed on a monthly basis It is feasible for user metering, but it is not enough for relevant supply departments to conduct deeper analysis and management decision-making. The actual demand of the industry has given birth to the continuous development of automatic meter reading system technology and application.
