CWL100 Wireless Data Logger

for monitoring humidity and temperature

CWL100 Cloud Wireless Data Logger is part of the Vaisala Jade Smart Cloud monitoring system. It is used to monitor humidity and temperature in a wide range of environments, such as warehouses, museums and other public buildings, production areas, cleanrooms, and laboratories. CWL100 is also suitable for construction moisture measurement.

LoRa™ wireless technology

CWL100 uses long range LoRa™ wireless technology. It connects wirelessly to the Vaisala Jade Smart Cloud service via the CA10 Cloud Access Point. Jade provides real-time data and trend graphs. The LoRa modulation technique provides a robust wireless signal that is extremely reliable over long distances and in complex, obstructed conditions.

CWL100 supports several probe types for humidity and temperature measurement in ambient and demanding applications. The probes use Vaisala HUMICAP humidity sensors and platinum temperature sensors for superior stability.  The probes are detachable, and easy to switch out for calibration. Jade Smart Cloud service detects the changed probe information automatically and maintains accurate and complete historical records.
