Shenzhen Qianhai Lensen Technology Co., Ltd mainly designs and produces industrial wireless data communication products including RF module, radio modem, DI, DO, AI, AO module and kinds of RF based remote control, telemetry systems and IOT products.

Our products are widely used in oil, gas, water, power industry, wireless alarm and security systems, intelligent traffics and irrigation, industry automation and many other M2M applications. RF data modules just instead the RS232, RS485 cable between different equipments to transmit serial data. RDIO series are designed for industry ON-OFF control. They are widely used for pump, valve, tank, motor, light, alarm control. RAIO series are used to collect voltage (0-5V) or current (4-20mA) signal. They are widely used to collect kinds of sensors data and signal. The GPRS RTU is suitable for transferring data from device to internet, and transferring data from internet (Monitoring center or server) to device.

Lensen commits to provide our customers better products and service. Our engineers are experts with more than 10 years experience in this field, rising to the challenge of developing high tech and competitive products.
