I have two 900MHz wireless mesh XBee-Pro communications modules (XBP9B-DMST-002) and (XBP9B-DMUT-002). See order number 489035. One is on an XBee-to-Ethernet modem and the other is on a ProXR 1-channel relay.
Both XBee modules provide a temperature reading (I’m guessing on the XBee itself). When I deployed these in the field, the temperatures shot up to around 45-50 deg. C. (150degF). I just don’t believe this as the ambient temperature is around 80degF. When I had the devices in the shop for testing, the temperatures seemed reasonable. The specs for the XBee say it will work up to 80degC.
Today, when one of the XBee on the relay was reading 150degF, I touched it and it was barely warm. Its enclosure was open to the ambient air. Reading the temperature is interesting, but not critical to my operation, however, I’m wondering if this is “normal” or is there any way to calibrate the temperature?
Thanks.
