Wireless Humidity Sensor


How it fits into the alarm platform: 

Connects wirelessly to the BarnTalk Gateway. For best results, we recommend one humidity sensor for every room or approximately every 100 feet in larger buildings with open air spaces. The humidity sensor should be placed within ~700 feet of the BarnTalk Gateway. On multi-barn sites, the humidity sensor’s range can often extend across multiple buildings depending on proximity.
