1.1.1 RF Performance

  • TX Power 14 dBm (25 mW)
  • RX Sensitivity -137 dBm
  • Approx. 10 km range
  • Integrated PCB antenna

1.1.2 Environment

  • Operating temperature -40°C to +85°C
  • Storage temperature 30°C recommended (to limit battery self-discharge)
  • Rel. humidity 0% to 95% (not condensing)

1.1.3 Options

  • External antenna
  • SDK for your SW development purposes
  • 10-30V external power supply
  • Compatible with the NEMEUS PicoGateway for private networks

1.2 Installation

By using the internal antenna, the position of the sensor is critical.

Install your product as high as possible, and prefer unobstructed area (concrete and metal are the worst materials).

If you cannot fulfill these conditions, it is still possible to use an optional external antenna.

2 Mechanics

  • Dimensions 60 x 95 x 85mm (109mm including fixing brackets)
  • 96mm spacing between brackets
  • IP 65
  • Solid ABS & PC material

3 Features

  • three modes: UART CMOS level, RS232 and RS485 bus.
  • Modbus slave device.
  • allows to connect a PLC to sigfox or LoRaWAN network.
