Relative Humidity & Temperature Duct Sensor

This is a duct sensor with 2M cord for easy installation which provides relative humidity and temperasture readings via Modbus-RTU as well as analog outputs.  These are often used with dehumidification systems which are integrated into existing ductwork.  For example, An ECM blower and zone valve can be controlled based on indoor relative humidity coming back from an ERV exchaust duct reading.
