Narrative:
Just after takeoff during the after takeoff checklist; I noticed that right outboard btms (brake temperature monitoring system) indicator was indicating 7. I monitored it briefly and it went up to 8. I elected to lower the landing gear to prevent any further temperature rise or a possible undetected fire. Just before I did so the indication spiked to 20 and hovered there between 17 and 20 (after deployment of the landing gear) though it slowly went down after approximately 10 minutes. Since I was unable to determine if it was an indication problem (as I suspected) I elected to declare an emergency and return to the field. We landed and had the emergency vehicles inspect us and get a brake temperature reading before we taxied back to the gate. It appears that it was a faulty brake temperature sensor on the outboard brake.
