Nanjing Shengyi Technology Co., Ltd. was established in 2007 and is located in Jiangning Development Zone, Nanjing City, Jiangsu Province. It is one of the few wireless sensor and networking product suppliers in China with independent wireless sensor networking protocols. Due to the advantages of long transmission distance and low power consumption (only one tenth of peers) of the company's wireless sensing products, they have been widely used in various aspects of food and drug production, transportation, storage, as well as fire protection, heating and other industries, providing product outsourcing services for dozens of domestic industry companies. Welcome friends from all walks of life to visit our company for inspection and negotiation of cooperation matters. Company History: In July 2007, Nanjing Shengyi Technology Co., Ltd. was established in Jiangning Development Zone, Nanjing. In December 2011, the company developed the first generation SWSN self-organizing network wireless sensing product, which increased the distance of wireless transmitters by 5 times compared to ZIGBEE and Wireless HART protocols at that time, while reducing power consumption to 50% of Wireless HART protocol products. In June 2015, the company developed the SWSN-R2 wireless router with proprietary protocol and intellectual property rights, which can achieve cellular expansion of wireless sensor networks with 3 hops, while retaining 99.5% transmission reliability. It has improved transmission reliability by 1-2 orders of magnitude compared to peers with more than 3 hops. In December 2016, the company developed wireless sensing products that are compatible with spread spectrum LORA technology and have a relay free distance of over 5 kilometers, as well as wireless measurement and control products that support NBIOT GPRS 4G networks. The products further enrich their product features? Does it have functions such as data display, wireless transmission, data recording (optional), and data supplementation (optional)? Ultra low power consumption, 5-second sampling interval battery life of 3 years (at room temperature), 1-minute sampling interval battery life of 8 years? Our proprietary network protocol with low-power long-distance features, with line of sight of 1000 meters, 5000 meters (optional), and no distance restrictions (NBIOT 2G 4G network)? Can wireless repeaters with proprietary intellectual property of the company achieve cellular network expansion? Wireless transmission network SWSN self-organizing network, 2G, 4G, NB optional
