CT101 – LoRaWAN RMS Current Sensor with NTC Probe – Milesight
 General Description
 Milesight 's CT101 is a smart RMS current sensor designed to measure power consumption using a greenhouse current sensor (CT Clamp). It also incorporates an NTC temperature probe for additional environmental readings. Thanks to LoRaWAN® connectivity, it enables reliable and accurate remote monitoring. Compact and easy to install, it is ideal for smart buildings, industrial installations, or electrical panels. Its measurement accuracy reaches ±1% for currents above 5 Arms.
