Omega’s new WiFi Temperature and Relative Humidity Transmitter features a stand-alone, compact, battery powered design that transmits measurements back to a host receiver up to 90 m away. When activated the wireless transmitter will transmit readings continuously at pre set time interval that was programmed by the user during the initial setup. Each unit measures and transmits: Relative Humidity Reading, Ambient Temperature, RF Signal Strength and Battery Condition to the receiver and is displayed on your PC screen in real time using the provided software. When used with host receiver model UWTC-REC1 data from up to 48 wireless transmitters can be received and displayed. Each unit includes free software that converts your PC into a strip chart recorder or data logger so readings can be saved and later printed or exported to a spread sheet file. When used with host transceiver model UWTC-REC2 wireless data from one unit can be re-transmitted out of the receiver by a wired connection as a analogue voltage or current signal to interface with a controller, PLC or data acquisition board.

The UWTC-REC3 receiver will work with up to 32 transmitters and features an Ethernet interface. The unit serves it's own web pages displaying data in numeric or graphical format which can be read using a standard web browser over a local network or the internet.
