Ambient Temp Sensor (ETLW)
Visit the online store page
Requires the eGauge Sensor Hub and eGauge model EG4xxx (Pro or Core), not compatible with older model units.
Only use straight-through RJ-11 cables to connect powered sensors to the Sensor Hub. Telephone systems generally use "reverse" style RJ-11 cables which are incompatible with the Sensor Hub. See this article for more information on verifying the correct RJ-11 wiring. Every Sensor Hub compatible sensor sold by eGauge Systems comes with a straight-through RJ-11 cable.
The eGauge Ambient Temperature Sensor (ETLW) is used in conjunction with the Sensor Hub and an EG4xxx model meter (Core or Pro) to record temperature data from systems such as HVAC systems, cold storage, data centers and other controlled environments. For fluid temperature monitoring, see the Temperature Probe Sensor (ETN100).
