Product details: Wifi device for recording temperature and humidity
The EL-WiFi-TH is an environmental sensor designed to measure temperature and humidity with an accuracy of ±0.3°C for temperature and ±2.0% RH for humidity.
Data is transmitted wirelessly over any WiFi network and can be accessed on a computer using free software or via the EL-WiFi-Cloud™ platform.
During configuration, the device scans for available wireless networks while connected to a computer, allowing it to connect to any WiFi network within range.
If the device temporarily loses connection, it continues logging data internally and automatically uploads it once the connection is restored (up to 120 days of storage at a 10-second sampling interval).
