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.
L 183 x W 145 x H 40mm
-20°C to +65°C.
For operation in extreme temperatures, the device must be fitted with Lithium Batteries.
4.5 - 16V
4 x C Cell Battery holder fitted and screw terminals for line power.
Flexible options - from "off the shelf" Alkaline to LiSO2 and 12V options.
The Eagle is ultra-low power and can run off a set of batteries for many years, including powering sensors. External power can be used if available.
External Power Input
4.5V – 16V
The internal battery can be used as a backup to operate when external power fails or is not present.
Fit both 4 x C Cell batteries and connect to line power. If there is a power cut the batteries will power the device.
The innovative battery meter gives an accurate reading of the energy being used from the battery, allowing for superior battery life prediction and monitoring.
The Eagle is available in 2 versions.
2G: SARA-G350-02S-01: 850/900/1800/1900 MHz
4G LTE Cat-M1 and NB-IoT:
uBlox SARA-R410M Modem operates on all major global LTE-Cat-M1 and NB-IoT bands.
Supported LTE bands:
1*, 2, 3, 4, 5, 8, 12, 13, 18, 19, 20, 25, 26*, 28 (*roaming bands)
Hinged Micro-SIM Holder (3FF)
The Eagle has a U.FL connector on the PCB that connects to an internal cellular antenna by default. This offers the option of installing an external antenna if maximum range is required.
Firmware and parameters can be changed Over-The-Air (OTA) using Digital Matter’s device management platform “OEM Server”
- UBLOX EVA-M8Q GPS Module
- Low-noise amplifier (LNA)
The GPS design allows the Eagle to operate as a high performance tracking device or to obtain occasional position and time updates
High Performance internal patch antenna
Offline Assist GPS satellite data is downloaded via the cellular network and stored in flash memory – used to dramatically improve the TTFF (time to first fix) and performance of the GPS
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
Switched Sensor Power (Vout)
Used to control the battery power to external sensors and peripherals. Load limited and short circuit protected. Output voltage is the same as input voltage.
I2C (inter-IC communications) is an interface commonly used in sensor modules. This allows the Eagle to talk to a wide range of sensors including: temperature, humidity, vibration, CO2 gas and many others. (requires firmware support - contact Digital Matter about sensor support)
3.3V Switched Power
Used to control the 3.3V power to external sensors and peripherals. Load limited and short circuit protected.
3 x Digital Inputs
Configurable for Pull-up/Pull-Down
Wake-up from deep sleep
Can be used for low power pulse counting
Max input voltage 48V
Thresholds: ‘Low’ below 1.0V, ‘High’ above 2.6V (approx.)
2 x Analogue Inputs
Input range 0-30V with Auto Ranging
0-5V Range: 1.22mV precision
0-30V Range: 7.32mV precision
2 x Digital Outputs
The switched ground outputs can be used to control external devices and circuits, for example to turn a lighting tower on/off
2 x 4-20mA inputs
The 4-20mA inputs can be used to interface to current loop sensors. 0.025mA precision.
The RS-485 interface can be used to interface to devices that support this interface, including MODBUS.
This is catered for in hardware and will require specific firmware integration.
1-wire or "i-Button" can be used to read Dallas tags, or interface to sensors using the 1-wire interface.
The Bluetooth Low Energy v5 module can be used to interface to BLE sensors and peripherals, or can be used to scan for BLE tags. This is an exciting new option and adds massive flexibility to the device.
(may require specific firmware integration)
3D accelerometer to detect movement.
The flash memory is used to store non-volatile information like parameters and data records. The flash memory is large enough to store approx. 30,000 records.
Test Button & LED
Easy do do in-field testing.
