Mechanical Features

Low-profile IP67 rugged housing

The IP67 rated housing is made of sturdy ABS/Polycarbonate plastic to survive bumps and knocks and 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 183 x W 145 x H 40



This interface is commonly used in agricultural sensors and measurement devices for soil moisture probes, temperature, electrical conductivity (EC) of soils, water levels / pressures, other SDI-12 probes and sensors.

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

3 x digital inputs, 0-48V

2 provide low power pulse counting

Analogue Inputs

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

Built-in battery voltage monitoring



Sigfox (LPWAN)

Sigfox Zones RCZ1, RCZ2, RCZ4

External antenna External ISM band antenna provides for maximum link budget with the flexibility to install a high-gain antenna if needed. Especially important for long range in rural agriculture applications.
Power (4-6V) The SensorData is ultra-low power and is designed to run off a set of 4 x “C” cell Alkaline batteries for a full season. This includes powering the sensors and SDI-12 probes. These 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.

Switched Sensor Power

(6V or 12V)

Used to control the battery power to external sensors and peripherals. Load limited and short circuit protected. 12V capable boost is available to supply SDI-12 sensors, especially over long cable runs.
3.3V Switched Power Used to control the 3.3V power to external sensors and peripherals. Load limited and short circuit protected.
GPS The optional GPS module allows the SensorData to periodically update its location and time. Know the exact position of your sensors, and obtain an accurate time update.

Via USB cable for firmware updates.

Via over the air (OTA) downlinks for configuration

Test Button Convenient to test installation and wiring.
Status LED Visual feedback in the field for testing
