M2M Sensor Module for LoRa Networks

The EPM2M-NORAM Sensor Module is a wireless sensor for Semtech LoRa based wireless sensor networks.

Download the Datasheet

The EPM2M-NORAM includes sensors for GPS, pressure, accelerometer, humidity and temperature. By leveraging LoRa, Embedded Planet has created a complete wireless sensor solution which provides low power consumption and can be use in harsh and challenging RF environments.

The EPM2M-LR-NORAM uses the ARM Cortex M3 processor and LoRA module to minimize space and save power. The EPM2MSM- NORAM sensors connect seamlessly to the EPM2M-LORA Gateway to allow LoRaWAN access for a secure connection.
