| UniTorq Wireless has come up with a solution for measuring temperature remotely in compost piles. UniTorq has designed a battery powered temperature sensor that will return temperature data through a wireless mesh network. The temperature sensor will use a thermocouple to acquire the temperature from the compost pile.
Wireless Mesh Network Defined
Unlike traditional wireless networks where each device must transmit to a hub, all devices in a mesh network act as both repeater and router, relaying traffic for any other device. The ability of the units to act as repeaters, gives us the ability to transport data using low power consumption.
The MESH network has the following features:
Auto-routing allows the individual radios to determine how they will route a packet to its ultimate destination without the path being preselected. The mesh network signals look for the most efficient way home, by this we mean using the least number of hops between radios.
Auto-pathing occurs when a message cannot find its intended receiver. At this point, the unit will automatically choose another path for the message.
Self-healing occurs when a previously out of commission unit comes back into the network. The reentry is accomplished by a broadcast message. The units that answer are put into the radio’s routing table along with their signal strength.
Gateway
The gateway connects the remote sensors to a wired Network or Host computer through a variety of communication devices such as Ethernet, Ethernet/IP, OPC, ModBus, TCP/IP, DLL and it also gives you the ability to get the information through the Web.
Enclosure
The enclosure is corrosion resistant and waterproof to NEMA 4 and 4X. There will be no external components; the wireless antenna will be inside the enclosure. |
