Outdoor Sensor System (OSS)
Built for Tough Environments
Outdoor Sensor System (OSS) is a line of wireless sensor products.
Capitalizing on decades of our experience designing high-reliability electronics for demanding environments,
the OSS was engineered to withstand harsh weather conditions continuously.
Surface or Pole Mounting
Attach your OSS device to a flat surface using the included bracket.
This method is ideal for mounting OSS devices on internal and external walls, beams, and other flat surfaces.
Mount OSS devices on standard 5cm (2") pipes using the included metal lips.
This option is great for agricultural applications that require external sensors for soil measurements.

Onboard or External Sensors
Housed inside the Sensor Pod, onboard sensors facilitate monitoring of various environmental parameters, such as
temperature, humidity, CO2, PPM, and others.
Sensor Pods feature ventilation holes, enabling air to flow over the sensors.
An internal partition hermetically insulates the rest of the device from the sensor compartment.
The Modbus Pod connects your OSS device to external Modbus sensors.
This option facilitates the use of external probes to measure the parameters of
soil, water, air, wind, rainfall, or sunlight.
Modbus support makes OSS devices compatible with a myriad of industry-specific sensors.
The attached Modbus cable is rodent-resistant and enters the device through a watertight gland.

Flexible Powering Options
Battery Power
OSS devices are optimized for battery power and may provide up to three years of operation on a single battery.
When equipped with a battery and onboard sensors, an OSS device is fully self-contained and requires no external connections.
Line Power
Alternatively, power may be supplied externally through a rodent-resistant power cable connecting to the side of the device.
OSS may be ordered with an onboard battery, line power, or both.
Powering Modbus Sensors
OSS models with Modbus pods can power attached sensors.
The power is sent through the same "bottom" cable carrying the Modbus signals.
OSS conserves the battery by powering external sensors only when it's time to take the readings.
Powering From Modbus Sensors
In a reversal of the roles, OSS devices may be powered by an external Modbus sensor.
This is similar to using the side (line) power, except that the power to the OSS is supplied through the Modbus cable.

Auxiliary Power Port
What if an OSS unit requires management, but its internal battery is depleted,
and no other power source is available?
Bring the device back to life with a USB power bank!
The included USB power cable is equipped with a magnetic connector that attaches
to an auxiliary power socket on the side of an OSS device.
Maintenance-in-Place
The OSS has been designed to simplify the on-site device maintenance and repairs:
Remove the Sensor Pod.
Slide out the internal subassembly.
Replace the battery or the entire subassembly.
Slide the subassembly back in.
Reattach the Sensor Pod.
Done, all without dismantling the device or disconnecting external wires.

Cloud Uplink Options
OSS devices securely send collected sensor data to the cloud.
Initially compatible with Microsoft Azure IoT Hub,
OSS may be adapted to virtually any public or private cloud service.
The product supports two-way cloud communications, enabling data uploads and remote management of OSS devices,
including the over-the-air (OTA) firmware upgrades from the cloud.
Wi-Fi Only Version
Available immediately, Wi-Fi-only ("W") OSS models are great for installation inside and outside buildings,
greenhouses, grow rooms, and other facilities with Wi-Fi coverage.
Wi-Fi + LTE Version
Supporting Cat-M1 and NB-IoT LTE, Wi-Fi/4G ("W"+"C") devices can be installed virtually anywhere.
Great for deployments across vast urban areas, farm fields, and forests,
these models facilitate the creation of large-scale distributed sensor networks.
NFC and Bluetooth for On-Site Management
Physical security is paramount to any sensor deployed in an outdoor area.
OSS devices have no exposed buttons to prevent unauthorized access.
All close-range interactions with an OSS unit require NFC authentication using the
OSS Companion App.
The App:
- Provides NFC authentication and password management
- Enables device configuration via Bluetooth Low Energy (BLE)
- Supports on-site over-the-air (OTA) firmware updates via BLE
