Wireless Data Acquisition System

The new coalesenses wireless data acquisition system enables easy forwarding of sensor data into the cloud. Available from mid 2014, it offers connectivity to a wide range of user sensors by providing a multitude of analog and digital interfaces.

Wireless Sensor Network: One or more user sensors are connected to each wireless device. The devices self-organize into a redundant wireless multi-hop mesh-network, forwarding data to the gateway. They use an innovative low power listening technology to keep up connectivity amongst each other while offering years of autonomous operation from standard batteries.

Gateway: The gateway connects the sensor network to the Internet via communication technologies such as GPRS or Ethernet. It allows data to flow from the sensor network to the cloud, and configuration information and commands from the cloud to the sensor devices.

Cloud: The cloud-based data storage and analysis application collects the data and stores it in a data base. It provides a convenient user interface to visualize sensor data, allows for device configuration and user notifications in case sensor data exceeds pre-defined thresholds.

Applications

The system targets all types of low data rate sensing, applications include but are not limited to Energy monitoring Object tracking Process automation and control Conditional maintenance Environmental monitoring Weather monitoring Structural heal monitoring Physical safety and perimeter monitoring Smart agriculture and irrigation control

Devices

The rugged sensor devices provide IP66 protection and offer different enclosure sizes to fit a wide range of sensing applications. Power supply choices include primary batteries, solar power, and 5..24V DC. An optional user interface (display and rotary controller) provides configuration and sensor data access right at the device. The devices feature a modular structure, where two expansion boards can be used to adopt between the interface of the internal or external sensor and the digital wireless devices. Like this, each device can integrate one or more user sensors into the wireless sensor network. Optionally, each expansion board can provide a switchable, user defined output voltage to power an external sensor exactly when needed. Currently, the following interface boards are available: RS232 RS485 4..20mA 0..5V Wheatstone Bridge SPI I2C Digital inputs and outputs
