SensorNode LoRaWAN

Mechanical Features

Low-profile IP67 rugged housing

The IP67 rated housing is made of sturdy ABS/Polycarbonate plastic to survive bumps and knocks and to survive many years in the sun and weather. It is low-profile and caters for a number of cable glands to allow for waterproof cable entry to the housing. The housing screws together for easy assembly, and has convenient mounting tabs.

Operating temperature

-20°C to +60°C

For operation in extreme temperatures the device must be fitted with Lithium batteries

Dimensions (mm) L 135 x W 90 x H 35


I2C Interface

I2C (inter-IC communications) is an interface commonly used in sensor modules. This allows the SensorNode to talk to a wide range of sensors including: temperature, humidity, vibration, CO2 gas and many others. Contact Digital Matter about sensor support.

Digital Inputs

2 x digital inputs, 0-48V

Optimised for low power pulse counting

Analogue Inputs 2 x analogue inputs, 0-30V with auto-ranging



LoRaWAN, 868 and 915MHz

Antenna Tuned PCB antenna
Power The SensorNode is ultra-low power and is designed to run off a set of 3 x AA cell Alkaline batteries. The off-the- shelf batteries are low cost and readily available. It can also be powered by a USB 5V wall socket if permanently installed in a location with power.
Sleep Current


10µA (micro-amps)

3.3V Switched Power Used to control the 3.3V power to external sensors and peripherals. Load limited and short circuit protected.

Option to fit to PCB at manufacturing time.

GPS module allows the SensorNode to periodically

update its location and time.

Configuration Via USB cable for firmware updates and parameters Future firmware will cater for parameter updates over- the-air (OTA) via downlink messages
Test Button Conveniently test installation and wiring.
Status LED Visual feedback in the field for testing
