Adeunis Modbus

The Adeunis LoRaWAN Modbus Master is a ready-to-use radio transmitter with a Modbus interface. This product meets the needs of users to communicate with one or several Modbus slaves and transmit the information via a LoRaWAN, Sigfox or Wireless M-Bus network.

  • Can handle up to 10 slaves with 15 registers by slave
  • Transmits the data from the slaves either periodically or in an event-related way based on high or low thresholds
  • The configuration of the transmitter is accessible by the user via a micro-USB port or remotely via the LoRaWAN network, allowing in particular a choice of modes of transmission, periodicity or triggering thresholds
  • Powered by an external power supply (not included)
  • Can provide and control the power supply for a slave

Elsys ELT

ELT-1 and ELT-2-HP are general LoRaWAN devices for measuring analogue or digital signals. ELT-1/ELT-2-HP can be used together with electricity meters, flow meters, analogue sensors, moisture sensors, temperature sensors, water leak cable or ultrasonic distance sensors. They are enclosed in an IP65 box and are designed to be outside. Inside the ELT-1/ELT-2-HP you will find three internal sensors: a temperature sensor, a humidity sensor and an accelerometer for orientation measurements.

Elsys ELT-1 Technical Specifications

Dual external connections. This makes it possible to do for example: External temperature + door switch
