How it fits into the BarnTalk system:

The Bird Scale Platform should be used with the Wireless Bird Scale, if you do not already have an existing bird platform. 

The Bird Scale connects wirelessly to the BarnTalk Gateway. MUST be used in conjunction with MTech's SONAR platform. The Bird Scale Sensor should be placed within ~700 feet of the BarnTalk Gateway. On multi-barn sites, the Bird Scale Sensor’s range can often extend across multiple buildings depending on proximity. We recommend two scales for typical houses, and three scales for larger houses.
