1.  Introduction

1.1 ​ What is POM01-NB NB-IoT Power Outage Monitoring Sensor

The POM01-NB integrates NB-IoT wireless module, which sends signals to the cloud platform when triggering alarms or timed reports, and is suitable for remote monitoring scenarios with wide coverage and low power consumption.

The POM01-NB adopts optocoupler isolation technology to detect whether the 220V power supply is normal or not, and can set the 180V low voltage trigger threshold to start the alarm logic immediately when the voltage drops abnormally.

The main power supply of POM01-NB is directly powered by 220V AC, and the backup power can be seamlessly switched after a power failure, guaranteeing continuous operation for 30 days.

POM01-NB has a wide temperature operating range, and the battery supports cyclic charging and discharging, adapting to complex industrial environments.

POM01-NB supports BLE configure and wireless OTA update which make user easy to use.

POM01-NB supports different uplink methods include TCP, MQTT, UDP, MQTTs or CoAP for different application requirement. and Support Uplinks to various IoT Servers.

POM01-NB has optional built-in SIM card and default IoT server connection version. Which makes it works with simple configuration.

1.5  Sleep mode and working mode

Deep Sleep Mode: Sensor doesn't have any NB-IoT activate. This mode is used for storage and shipping to save battery life.

Working Mode: In this mode, Sensor will work as NB-IoT Sensor to Join NB-IoT network and send out sensor data to server. Between each sampling/tx/rx periodically, sensor will be in IDLE mode), in IDLE mode, sensor has the same power consumption as Deep Sleep mode.

1.6  Button & LEDs

1.7  BLE connection

POM01-NB support BLE remote configure and firmware update.

BLE can be used to configure the parameter of sensor or see the console output from sensor. BLE will be only activate on below case:

• Press button to send an uplink
• Press button to active device.
• Device Power on or reset.

If there is no activity connection on BLE in 60 seconds, sensor will shut down BLE module to enter low power mode.

1.8  Pin Definitions , Switch & SIM Direction

1.8.1 Jumper JP2

Power on Device when put this jumper.

2.  Use POM01-NB to communicate with IoT Server

2.1  Send data to IoT server via NB-IoT network

There are two version: -GE and -1T version of POM01-NB.

GE Version: This version doesn't include SIM card or point to any IoT server. User needs to use AT Commands to configure below two steps to set POM01-NB send data to IoT server.

• Install NB-IoT SIM card and configure APN. See instruction of Attach Network.

• Set up sensor to point to IoT Server. See instruction of Configure to Connect Different Servers.  

Below shows result of different server as a glance.
