Product Description
AVTECH Digital Active Power Sensor with Temperature – 10 ft RJ-11 Cable, Plug-and-Play for Room Alert Monitors
This used AVTECH Digital Active Power Sensor (model RMA-APS10-SEN) provides real-time monitoring of both power status and temperature for any AC-powered electrical device . The sensor simply straps onto an existing power cord, allowing you to monitor whether a device is drawing power without cutting cables or unplugging equipment .
The sensor detects active power when the connected device draws more than 100 Watts (up to 1800W) with an accuracy of ±2.5W . When power is detected, the sensor reports “Active” status; when power drops below this threshold, it reports “Inactive” . A built-in green LED provides quick visual confirmation of power status .
Additionally, this sensor includes a digital temperature sensor that measures ambient temperature from -40°F to 185°F (-40°C to 85°C) with ±2°C accuracy .
Condition Note: This unit is untested and sold as-is. This listing is for the sensor only; no Room Alert monitor is included.
