DataStream Wireless Landfill Gas Monitor

The DataStream Wireless Sensor Network System is an adaptable network architecture allowing rapid commissioning of wireless monitoring networks. The DataStream Wireless Landfill Gas Monitor provides an expandable system for ambient and perimeter ground gas monitoring.

With ‘out the box’ auto mesh wireless functionality and low power requirements, the DataStream Wireless Landfill Gas Monitor can be easily installed at a remote location and connected to multiple ground probe sampling tubes at different heights. The node wakes up to 4 times a day (programmable) and using an internal compressor to draw an air sample from each of the ground probes in sequence and takes a gas reading. The readings are sent over a mesh wireless system to an on-site DataStream Wireless Monitoring System Gateway where they are time stamped and logged. Data may be downloaded from the Gateway onsite (programmable) or continuously monitored in real time over a WAN connection such as a cellular modem. Users can log into the gateways internal server to view the data and set up email/sms alarms.
