ES311 is a 3G (W-CDMA) waterproof GPS tracker. It supports TCP/UDP and HTTP for reporting location and sensor information. Other than the basic feature of location report, it can be integrated with relay, camera, RFID reader, fuel sensor, humility sensor, flow meter and many other sensors with 5 IOs (factory configurable combinations of up to 3 digital inputs, 2 digital outputs, 3 analog inputs (A/D), 1 UART or 1 RS232C). It can work in humid environment because of its waterproof design.
