APPLICATIONS
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 |
Interfaces
|
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 |
Specifications
|
Network |
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 |
10 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. |
| GPS |
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 |
