Self-organized networks with APC340(based on SX1278) for gas meter
Specification:
The communication coverage is large and the network is more robust. A few nodes are offline and do not affect other meters online;
High measurement accuracy and reliability; long service life and wide applicability;
High safety factor with configuration logic encryption card to prevent copying and decryption;
Low power consumption with micro-assembly design of the main control board that complies with ISO 7861-1/2/3 standards and maintains a current of less than 2.5uA when sleeping;
Electronic backpack design with built-in high-integration control board processed by three-proofing technology that effectively protects smart meters;
Reliable mechanical and electronic full-life design that requires no maintenance for ten years;
Multiple functions such as anti-magnetic interference, power-off protection, over-current protection and anti-theft gas.
