Wireless Temperature/Humidity

8.1 Introduction
This is our standard CTXL-TRH recorder, except that the temperature/humidity
probe is wireless. The wireless probe consists of a temperature/humidity
wireless transmitter and a wireless receiver.
The wireless transmitter has a built-in temperature/humidity sensor that
measures the air quality (Temperature & Humidity). It then transmits the data to
a wireless receiver thru an RF link. The transmitter is operated from one AA size
lithium battery and/or a DC adapter input. The transmitter also has two LED
indicators. One Green LED is for transmission indication. One Red LED is for
low battery indication as well as other wireless communication errors.
The wireless receiver plugs directly to the circular chart recorder where a
temperature/humidity probe is normally plugged into. The wireless receiver
acts as a probe, so the wireless RF link is totally transparent to the circular chart
recorder. The recorder thinks that it is directly connected to the probe. This
design allows us to offer the wireless probe as an option to all existing recorders
in the field. There is no internal upgrade required to make a standard circular
chart recorder wireless.
