Spinwave Systems, Westford, MA, offers wireless humidity sensors for commercial building control and industrial automation. The sensors are temperature compensated and factory calibrated, use the company's A3 wireless technology, and are available in room RH sensor models and combination temperature/RH sensor models. Accuracy is ±2% RH. You can interface the sensors to a building automation system by mapping a sensor's values to analog outputs on the company's Direct I/O interface board or map sensor data to preconfigured protocol objects, such as BACnet objects, LON SNVTs, or Modbus registers.
