0seandogue 11 years ago The question is a bit lacking in details on the transceiver and the temperature sensor, so a detailed response is difficult. If the temp sensor is an analog output device, the first thing you'll need is signal conditioning at or nearby the sensor, to optimize its range and convert its output to a usable value by the transmitter. Of course, the specific circuit is dependent on the type of sensor, and the transmitter. I really can't say much more than that based on your post. The bare minimum details needed are the input interface for the transmitter, including range and format, and the sensor type and output characteristics.
